Subject: [PATCH 0001/1816] ocfs2: Always include ACL support
To become consistent with filesystems such as XFS or BTRFS, make posix
ACLs always available. This also reduces possibility of
misconfiguration on admin's side.

Subject: [PATCH 0002/1816] ocfs2: Make acl use the default
Change acl mount options handling to match the one of XFS and BTRFS and
hopefully it is also easier to use now. When admin does not specify any
acl mount option, acls are enabled if and only if the filesystem has
xattr feature enabled. If admin specifies 'acl' mount option, we fail
the mount if the filesystem does not have xattr feature and thus acls
cannot be enabled.

Subject: [PATCH 0004/1816] ocfs2/cluster: Make fence method configurable - v2
By default, o2cb fences the box by calling emergency_restart(). While this
scheme works well in production, it comes in the way during testing as it
does not let the tester take stack/core dumps for analysis.
This patch allows user to dynamically change the fence method to panic() by:
# echo "panic" > /sys/kernel/config/cluster/<clustername>/fence_method

Subject: [PATCH 0005/1816] ocfs2: return -EAGAIN instead of EAGAIN in dlm
We used to return positive EAGAIN to indicate a retry action
is needed in dlm_begin_reco_handler(). Now we return negative
-EAGAIN to erase the confusion caused by this error code.

Subject: [PATCH 0006/1816] cifs: NULL out tcon, pSesInfo, and srvTcp pointers
when chasing DFS referrals
The scenario is this:
The kernel gets EREMOTE and starts chasing a DFS referral at mount time.
The tcon reference is put, which puts the session reference too, but
neither pointer is zeroed out.
The mount gets retried (goto try_mount_again) with new mount info.
Session setup fails fails and rc ends up being non-zero. The code then
falls through to the end and tries to put the previously freed tcon
pointer again. Oops at: cifs_put_smb_ses+0x14/0xd0
Fix this by moving the initialization of the rc variable and the tcon,
pSesInfo and srvTcp pointers below the try_mount_again label. Also, add
a FreeXid() before the goto to prevent xid "leaks".

This is actually fine for two reasons: we call vmalloc at mount time
then it's not in the swapping out path. Also the reiserfs lock can be
acquired recursively, but since its implementation depends on a mutex,
it's hard and not necessary worth it to teach that to lockdep.
The lock is useless at mount time anyway, at least until we replay the
journal. But let's remove it from this path later as this needs
more thinking and is a sensible change.
For now we can just relax the lock around vmalloc,

Subject: [PATCH 0011/1816] reiserfs: Fix reiserfs lock and journal lock
inversion dependency
When we were using the bkl, we didn't care about dependencies against
other locks, but the mutex conversion created new ones, which is why
we have reiserfs_mutex_lock_safe(), which unlocks the reiserfs lock
before acquiring another mutex.
But this trick actually fails if we have acquired the reiserfs lock
recursively, as we try to unlock it to acquire the new mutex without
inverted dependency, but we eventually only decrease its depth.
This happens in the case of a nested inode creation/deletion.
Say we have no space left on the device, we create an inode
and tak the lock but fail to create its entry, then we release the
inode using iput(), which calls reiserfs_delete_inode() that takes
the reiserfs lock recursively. The path eventually ends up in
journal_begin() where we try to take the journal safely but we
fail because of the reiserfs lock recursion:

Subject: [PATCH 0015/1816] ext4: replace BUG() with return -EIO in
ext4_ext_get_blocks
This patch fixes the Kernel BZ #14286. When the address of an extent
corresponding to a valid block is corrupted, a -EIO should be reported
instead of a BUG(). This situation should not normally not occur
except in the case of a corrupted filesystem. If however it does,
then the system should not panic directly but depending on the mount
time options appropriate action should be taken. If the mount options
so permit, the I/O should be gracefully aborted by returning a -EIO.

Subject: [PATCH 0017/1816] drm/i915: fix order of fence release wrt flushing
i915_gem_object_unbind had the ordering wrong. The other user,
i915_gem_object_put_fence_reg already has the correct ordering.
Results was usually corrupted pixmaps, especially garbled font glyphs
after a suspend/resume (because this evicts everything).
I'm still waiting for the feedback from the bug-reporters, but
because this obviously fixes a bug (at least for me) I'm already
submitting it.

Subject: [PATCH 0018/1816] drm/i915: Don't check for lid presence when
detecting LVDS
Checking for the presence of a lid in order to validate whether or not
an LVDS display exists fails on some development platforms that implement
a lid device but allow the LVDS to be disabled. The VBT is correctly
updated, but Linux assumes that an LVDS is still present and lies to
userspace. Remove the lid check and trust the VBT.

One problem in i915 hibernate with current legacy pci pm ops is
that after we do freeze, we'll be forced to do resume once again,
which re-init some resources and do modesetting again, that is
unnecessary for hibernate. This patch trys to bypass that.
We can't resolve this within legacy pm framework, but can do it
easily with new pm ops. Suspend (S3) process has also been kept
without change.

Subject: [PATCH 0021/1816] tc1100-wmi - add error handling for device
registration
Any of the platform API functions can fail; driver should be prepared
to handle such failures. Also:
- changed to platform_driver_probe() since the device is created
right there with the driver;
- added __devexit annotation to remove method;
- fixed memory leak on module unload - named platform_device_del() is not
enough to free platform device, need platform_device_unregister().

Subject: [PATCH 0023/1816] fasync: split 'fasync_helper()' into separate
add/remove functions
Yes, the add and remove cases do share the same basic loop and the
locking, but the compiler can inline and then CSE some of the end result
anyway. And splitting it up makes the code way easier to follow,
and makes it clearer exactly what the semantics are.
In particular, we must make sure that the FASYNC flag in file->f_flags
exactly matches the state of "is this file on any fasync list", since
not only is that flag visible to user space (F_GETFL), but we also use
that flag to check whether we need to remove any fasync entries on file
close.
We got that wrong for the case of a mixed use of file locking (which
tries to remove any fasync entries for file leases) and fasync.
Splitting the function up also makes it possible to do some future
optimizations without making the function even messier. In particular,
since the FASYNC flag has to match the state of "is this on a list", we
can do the following future optimizations:
- on remove, we don't even need to get the locks and traverse the list
if FASYNC isn't set, since we can know a priori that there is no
point (this is effectively the same optimization that we already do
in __fput() wrt removing fasync on file close)
- on add, we can use the FASYNC flag to decide whether we are changing
an existing entry or need to allocate a new one.
but this is just the cleanup + fix for the FASYNC flag.

Subject: [PATCH 0027/1816] drm/i915: Update LVDS connector status when
receiving ACPI LID event
Dirk reports that nothing is displayed on LVDS when using ubuntu 9.1 after
close/reopen the LID. And I also reproduce this issue on another laptop.
After some tests and debug, it seems that it is related with that the
LVDS status is not updated in time in course of suspend/resume.
Now the LID state is used to check whether the LVDS is connected or
disconnected. And when the LID is closed, it means that the LVDS is
disconnected. When it is reopened, it means that the LVDS is connected.
At the same time on some distributions the LID event is also used to put
the system into suspend state. When the LID is closed, the system will enter
the suspend state. When the LID is reopened, the system will be resumed.
In such case when the LID is closed, user-space script will receive the LID
notification event and detect the LVDS as disconnected. Then the system will
enter the suspended state. When the LID is reopened, the system will be
resumed. As the LVDS status is not updated in course of resume, it will cause
that the LVDS connector is marked as unused and disabled. After the resume is
finished,user-space script will try to configure the display mode for LVDS.
But unfortunately as the LVDS status is not updated in time and it is still
marked as disconnected, the LVDS and its corresponding CRTC will be disabled
again in the function of drm_helper_disable_unused_functions after changing
mode for LVDS.
So we had better check and update the status of LVDS connector after receiving
the LID notication event. Then after the system is resumed from suspended
state, we can set the display mode for LVDS correctly.

Subject: [PATCH 0028/1816] PCI/PM: Propagate wake-up enable for PCIe devices
too
Having read the PM part of the PCIe 2.0 specification more carefully
I think that it was a mistake to restrict the wake-up enable
propagation to non-PCIe devices, because if we do not request
control of the root ports' PME registers via OSC, PCIe PME is
supposed to be handled by the platform, just like the non-PCIe PME.
Even if we do that, the wake-up propagation is done to allow the
devices to wake up the system from sleep states which involves the
platform anyway, so it won't hurt.

Subject: [PATCH 0029/1816] PCI: Handle case when no pci device can provide
cache line size hint
Prior to this patch, if pci_read_config_byte(dev, PCI_CACHE_LINE_SIZE, ...)
returns 0 for all dev, pci_cache_line_size ends up set to zero
(instead of pci_dfl_cache_line_size).
This patch ensures the pci_cache_line_size = pci_dfl_cache_line_size
setting in the above scenario.
This happens in case of a kvm-88 guest (where, consequently, the rtl8139
NIC failed to initialize).

Subject: [PATCH 0033/1816] PCI: fix section mismatch on update_res()
Remark update_res from __init to __devinit as it is called also
from __devinit functions.
This patch removes the following warning message:
WARNING: vmlinux.o(.devinit.text+0x774a): Section mismatch
in reference from the function pci_root_bus_res() to the
function .init.text:update_res()
The function __devinit pci_root_bus_res() references
a function __init update_res().
If update_res is only used by pci_root_bus_res then
annotate update_res with a matching annotation.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The old include/drm/drm_pciids.h used to be generated from the libdrm
git repo. We don't use that anymore so just use a local list in the
driver like everybody else.

Subject: [PATCH 0037/1816] drm/i915: Implement IS_* macros using static tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Instead of using the IS_I9XX etc macros that expand to a ton of
comparisons, use new struct intel_device_info to capture the
capabilities of the different chipsets. The drm_i915_private struct
will be initialized to point to the device info that correspond to
the actual device and this way, testing for a specific capability is
just a matter of checking a bit field.

Subject: [PATCH 0039/1816] drm/i915: only enable hotplug for detected outputs
This patch changes around our hotplug enable code a bit to only enable
it for ports we actually detect and initialize. This prevents problems
with stuck or spurious interrupts on outputs that aren't actually wired
up, and is generally more correct.
Fixes FDO bug #23183.

Subject: [PATCH 0040/1816] reiserfs: Fix reiserfs lock <-> inode mutex
dependency inversion
The reiserfs lock -> inode mutex dependency gets inverted when we
relax the lock while walking to the tree.
To fix this, use a specialized version of reiserfs_mutex_lock_safe
that takes care of mutex subclasses. Then we can grab the inode
mutex with I_MUTEX_XATTR subclass without any reiserfs lock
dependency.
This fixes the following report:
[ INFO: possible circular locking dependency detected ]
2.6.32-06793-gf405425-dirty #2

Subject: [PATCH 0041/1816] PCI/cardbus: Add a fixup hook and fix powerpc
The cardbus code creates PCI devices without ever going through the
necessary fixup bits and pieces that normal PCI devices go through.
There's in fact a commented out call to pcibios_fixup_bus() in there,
it's commented because ... it doesn't work.
I could make pcibios_fixup_bus() do the right thing on powerpc easily
but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus
for which a weak empty implementation is provided by the PCI core.
This fixes cardbus on powerbooks and probably all other PowerPC
platforms which was broken completely for ever on some platforms and
since 2.6.31 on others such as PowerBooks when we made the DMA ops
mandatory (since those are setup by the fixups).

Subject: [PATCH 0045/1816] sh: Fix up MAX_DMA_CHANNELS definition when DMA is
disabled.
MAX_DMA_CHANNELS is tested for the total number of channels in order to
populate an IRQ map. Stub this out completely when no DMA support is
enabled -- as used to be the default behaviour before this was
generalized for use by the dmaengine code.

Subject: [PATCH 0047/1816] sh: fix DMA driver's descriptor chaining and cookie
assignment
The SH DMA driver wrongly assigns negative cookies to transfer descriptors,
also, its chaining of partial descriptors is broken. The latter problem is
usually invisible, because maximum transfer size per chunk is 16M, but if you
artificially set this limit lower, the driver fails. Since cookies are also
used in chunk management, both these problems are fixed in one patch. As side
effects a possible memory leak, when descriptors are prepared, but not
submitted, and multiple races have also been fixed.

Subject: [PATCH 0049/1816] ioat3: fix p-disabled q-continuation
When continuing a pq calculation the driver needs 3 extra sources. The
driver can perform a 3 source calculation with a single descriptor, but
needs an extended descriptor to process up to 8 sources in one
operation. However, in the p-disabled case only one extra source is
needed. When continuing a p-disabled operation there are occasions
(i.e. 0 < src_cnt % 8 < 3) where the tail operation does not need an
extended descriptor. Properly account for this fact otherwise invalid
'dmacount' values will be written to hardware usually causing the
channel to halt with 'invalid descriptor' errors.

-Anticipatory IO scheduler
--------------------------
-Nick Piggin <piggin@cyberone.com.au> 13 Sep 2003
-
-Attention! Database servers, especially those using "TCQ" disks should
-investigate performance with the 'deadline' IO scheduler. Any system with high
-disk performance requirements should do so, in fact.
-
-If you see unusual performance characteristics of your disk systems, or you
-see big performance regressions versus the deadline scheduler, please email
-me. Database users don't bother unless you're willing to test a lot of patches
-from me ;) its a known issue.
-
-Also, users with hardware RAID controllers, doing striping, may find
-highly variable performance results with using the as-iosched. The
-as-iosched anticipatory implementation is based on the notion that a disk
-device has only one physical seeking head. A striped RAID controller
-actually has a head for each physical device in the logical RAID device.
-
-However, setting the antic_expire (see tunable parameters below) produces
-very similar behavior to the deadline IO scheduler.
-
-Selecting IO schedulers
------------------------
-Refer to Documentation/block/switching-sched.txt for information on
-selecting an io scheduler on a per-device basis.
-
-Anticipatory IO scheduler Policies
-----------------------------------
-The as-iosched implementation implements several layers of policies
-to determine when an IO request is dispatched to the disk controller.
-Here are the policies outlined, in order of application.
-
-1. one-way Elevator algorithm.
-
-The elevator algorithm is similar to that used in deadline scheduler, with
-the addition that it allows limited backward movement of the elevator
-(i.e. seeks backwards). A seek backwards can occur when choosing between
-two IO requests where one is behind the elevator's current position, and
-the other is in front of the elevator's position. If the seek distance to
-the request in back of the elevator is less than half the seek distance to
-the request in front of the elevator, then the request in back can be chosen.
-Backward seeks are also limited to a maximum of MAXBACK (1024*1024) sectors.
-This favors forward movement of the elevator, while allowing opportunistic
-"short" backward seeks.
-
-2. FIFO expiration times for reads and for writes.
-
-This is again very similar to the deadline IO scheduler. The expiration
-times for requests on these lists is tunable using the parameters read_expire
-and write_expire discussed below. When a read or a write expires in this way,
-the IO scheduler will interrupt its current elevator sweep or read anticipation
-to service the expired request.
-
-3. Read and write request batching
-
-A batch is a collection of read requests or a collection of write
-requests. The as scheduler alternates dispatching read and write batches
-to the driver. In the case a read batch, the scheduler submits read
-requests to the driver as long as there are read requests to submit, and
-the read batch time limit has not been exceeded (read_batch_expire).
-The read batch time limit begins counting down only when there are
-competing write requests pending.
-
-In the case of a write batch, the scheduler submits write requests to
-the driver as long as there are write requests available, and the
-write batch time limit has not been exceeded (write_batch_expire).
-However, the length of write batches will be gradually shortened
-when read batches frequently exceed their time limit.
-
-When changing between batch types, the scheduler waits for all requests
-from the previous batch to complete before scheduling requests for the
-next batch.
-
-The read and write fifo expiration times described in policy 2 above
-are checked only when in scheduling IO of a batch for the corresponding
-(read/write) type. So for example, the read FIFO timeout values are
-tested only during read batches. Likewise, the write FIFO timeout
-values are tested only during write batches. For this reason,
-it is generally not recommended for the read batch time
-to be longer than the write expiration time, nor for the write batch
-time to exceed the read expiration time (see tunable parameters below).
-
-When the IO scheduler changes from a read to a write batch,
-it begins the elevator from the request that is on the head of the
-write expiration FIFO. Likewise, when changing from a write batch to
-a read batch, scheduler begins the elevator from the first entry
-on the read expiration FIFO.
-
-4. Read anticipation.
-
-Read anticipation occurs only when scheduling a read batch.
-This implementation of read anticipation allows only one read request
-to be dispatched to the disk controller at a time. In
-contrast, many write requests may be dispatched to the disk controller
-at a time during a write batch. It is this characteristic that can make
-the anticipatory scheduler perform anomalously with controllers supporting
-TCQ, or with hardware striped RAID devices. Setting the antic_expire
-queue parameter (see below) to zero disables this behavior, and the
-anticipatory scheduler behaves essentially like the deadline scheduler.
-
-When read anticipation is enabled (antic_expire is not zero), reads
-are dispatched to the disk controller one at a time.
-At the end of each read request, the IO scheduler examines its next
-candidate read request from its sorted read list. If that next request
-is from the same process as the request that just completed,
-or if the next request in the queue is "very close" to the
-just completed request, it is dispatched immediately. Otherwise,
-statistics (average think time, average seek distance) on the process
-that submitted the just completed request are examined. If it seems
-likely that that process will submit another request soon, and that
-request is likely to be near the just completed request, then the IO
-scheduler will stop dispatching more read requests for up to (antic_expire)
-milliseconds, hoping that process will submit a new request near the one
-that just completed. If such a request is made, then it is dispatched
-immediately. If the antic_expire wait time expires, then the IO scheduler
-will dispatch the next read request from the sorted read queue.
-
-To decide whether an anticipatory wait is worthwhile, the scheduler
-maintains statistics for each process that can be used to compute
-mean "think time" (the time between read requests), and mean seek
-distance for that process. One observation is that these statistics
-are associated with each process, but those statistics are not associated
-with a specific IO device. So for example, if a process is doing IO
-on several file systems on separate devices, the statistics will be
-a combination of IO behavior from all those devices.
-
-
-Tuning the anticipatory IO scheduler
-------------------------------------
-When using 'as', the anticipatory IO scheduler there are 5 parameters under
-/sys/block/*/queue/iosched/. All are units of milliseconds.
-
-The parameters are:
-* read_expire
- Controls how long until a read request becomes "expired". It also controls the
- interval between which expired requests are served, so set to 50, a request
- might take anywhere < 100ms to be serviced _if_ it is the next on the
- expired list. Obviously request expiration strategies won't make the disk
- go faster. The result basically equates to the timeslice a single reader
- gets in the presence of other IO. 100*((seek time / read_expire) + 1) is
- very roughly the % streaming read efficiency your disk should get with
- multiple readers.
-
-* read_batch_expire
- Controls how much time a batch of reads is given before pending writes are
- served. A higher value is more efficient. This might be set below read_expire
- if writes are to be given higher priority than reads, but reads are to be
- as efficient as possible when there are no writes. Generally though, it
- should be some multiple of read_expire.
-
-* write_expire, and
-* write_batch_expire are equivalent to the above, for writes.
-
-* antic_expire
- Controls the maximum amount of time we can anticipate a good read (one
- with a short seek distance from the most recently completed request) before
- giving up. Many other factors may cause anticipation to be stopped early,
- or some processes will not be "anticipated" at all. Should be a bit higher
- for big seek time devices though not a linear correspondence - most
- processes have only a few ms thinktime.
-
-In addition to the tunables above there is a read-only file named est_time
-which, when read, will show:
-
- - The probability of a task exiting without a cooperating task
- submitting an anticipated IO.
-
- - The current mean think time.
-
- - The seek distance used to determine if an incoming IO is better.

a task in one cgroup and having a pointer to cfqq in other cgroup.
Well I guess in some situations it can happen and that is, when a random
IO queue has been moved into root cgroup for group_isolation=0. In
this case, tasks's cgroup/group is different from where actually cfqq is,
but this is intentional and in this case merging should be allowed.
The second situation is where due to close cooperator patches, multiple
processes can be sharing a cfqq. If everything implemented right, we should
not end up in a situation where tasks from different processes in different
groups are sharing the same cfqq as we allow merging of cooperating queues
only if they are in same group.

Subject: [PATCH 0061/1816] cfq-iosched: Remove prio_change logic for workload
selection
o CFQ now internally divides cfq queues in therr workload categories. sync-idle,
sync-noidle and async. Which workload to run depends primarily on rb_key
offset across three service trees. Which is a combination of mulitiple things
including what time queue got queued on the service tree.
There is one exception though. That is if we switched the prio class, say
we served some RT tasks and again started serving BE class, then with-in
BE class we always started with sync-noidle workload irrespective of rb_key
offset in service trees.
This can provide better latencies for sync-noidle workload in the presence
of RT tasks.
o This patch gets rid of that exception and which workload to run with-in
class always depends on lowest rb_key across service trees. The reason
being that now we have multiple BE class groups and if we always switch
to sync-noidle workload with-in group, we can potentially starve a sync-idle
workload with-in group. Same is true for async workload which will be in
root group. Also the workload-switching with-in group will become very
unpredictable as it now depends whether some RT workload was running in
the system or not.

Subject: [PATCH 0063/1816] ARM: Convert VFP/Crunch/XscaleCP thread_release()
to exit_thread()
This avoids races in the VFP code where the dead thread may have
state on another CPU. By moving this code to exit_thread(), we
will be running as the thread, and therefore be running on the
current CPU.
This means that we can ensure that the only local state is accessed
in the thread notifiers.

Subject: [PATCH 0065/1816] x86: Fix objdump version check in chkobjdump.awk
for different formats.
Different version of objdump says its version in different way;
GNU objdump 2.16.1
or
GNU objdump version 2.19.51.0.14-1.fc11 20090722
This patch uses the first argument which starts with a number
as version string.
Changes in v2:
- Remove unneeded increment.

Fixing this:
[acme@doppio linux-2.6-tip]$ perf diff --hell
Error: unknown option `hell'
usage: perf diff [<options>] [old_file] [new_file]
Segmentation fault
[acme@doppio linux-2.6-tip]$
Also go over the other such arrays to check if they all were OK,
they are, but there were some minor changes to do like making
one static and renaming another to match the command it refers
to.

Subject: [PATCH 0069/1816] sunrpc: on successful gss error pipe write, don't
return error
When handling the gssd downcall, the kernel should distinguish between a
successful downcall that contains an error code and a failed downcall
(i.e. where the parsing failed or some other sort of problem occurred).
In the former case, gss_pipe_downcall should be returning the number of
bytes written to the pipe instead of an error. In the event of other
errors, we generally want the initiating task to retry the upcall so
we set msg.errno to -EAGAIN. An unexpected error code here is a bug
however, so BUG() in that case.

Subject: [PATCH 0082/1816] dma-debug: Do not add notifier when dma debugging
is disabled.
If CONFIG_HAVE_DMA_API_DEBUG is defined and "dma_debug=off" is
specified on the kernel command line, when you detach a driver from a
device you can cause the following NULL pointer dereference:
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<c0580d35>] dma_debug_device_change+0x5d/0x117
The problem is that the dma_debug_device_change notifier function is
added to the bus notifier chain even though the dma_entry_hash array
was never initialized. If dma debugging is disabled, this patch both
prevents dma_debug_device_change notifiers from being added to the
chain, and additionally ensures that the dma_debug_device_change
notifier function is a no-op.

The assumption that acpi_table_parse passes the return value
of the hanlder function to the caller proved wrong
recently. The return value of the handler function is
totally ignored. This makes the initialization code for AMD
IOMMU buggy in a way that could cause a kernel panic on
initialization. This patch fixes the issue in the AMD IOMMU

Subject: [PATCH 0085/1816] HWPOISON: Add PROC_FS dependency to hwpoison
injector v2
The injector filter requires stable_page_flags() which is supplied
by procfs. So make it dependent on that.
Also add ifdefs around the filter code in memory-failure.c so that
when the filter is disabled due to missing dependencies the whole
code still builds.

Subject: [PATCH 0086/1816] tracing: Fix setting tracer specific options
The function __set_tracer_option() takes as its last parameter a
"neg" value. If set it should negate the value of the option.
The trace_options_write() passed the value written to the file
which is what the new value needs to be set as. But since this
is not the negative, it never sets the value.

Subject: [PATCH 0087/1816] ACPI: disable _OSI(Windows 2009) on Asus K50IJ
Fix a win7 compability issue on Asus K50IJ.
Here is the _BCM method of this laptop:
Method (_BCM, 1, NotSerialized)
{
If (LGreaterEqual (OSFG, OSVT))
{
If (LNotEqual (OSFG, OSW7))
{
Store (One, BCMD)
Store (GCBL (Arg0), Local0)
Subtract (0x0F, Local0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
Else
{
DBGR (0x0B, Zero, Zero, Arg0)
Store (Arg0, LBTN)
^^^SBRG.EC0.STBR ()
...
}
}
}
LBTN is used to store the index of the brightness level in the _BCL.
GCBL is a method that convert the percentage value to the index value.
If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage
value which is surely beyond the end of _BCL package.

Subject: [PATCH 0092/1816] ACPI: processor: call _PDC early
We discovered that at least one machine (HP Envy), methods in the DSDT
attempt to call external methods defined in a dynamically loaded SSDT.
Unfortunately, the DSDT methods we are trying to call are part of the
EC initialization, which happens very early, and the the dynamic SSDT
is only loaded when a processor _PDC method runs much later.
This results in namespace lookup errors for the (as of yet) undefined
methods.
Since Windows doesn't have any issues with this machine, we take it
as a hint that they must be evaluating _PDC much earlier than we are.
Thus, the proper thing for Linux to do should be to match the Windows
implementation more closely.
Provide a mechanism to call _PDC before we enable the EC. Doing so loads
the dynamic tables, and allows the EC to be enabled correctly.
The ACPI processor driver will still evaluate _PDC in its .add() method
to cover the hotplug case.

Subject: [PATCH 0093/1816] ACPI: processor: introduce arch_has_acpi_pdc
arch dependent helper function that tells us if we should attempt to
evaluate _PDC on this machine or not.
The x86 implementation assumes that the CPUs in the machine must be
homogeneous, and that you cannot mix CPUs of different vendors.

Subject: [PATCH 0094/1816] ACPI: processor: unify arch_acpi_processor_init_pdc
The x86 and ia64 implementations of arch_acpi_processor_init_pdc()
are almost exactly the same. The only difference is in what bits
they set in obj_list buffer.
Combine the boilerplate memory management code, and leave the
arch-specific bit twiddling in separate implementations.

Subject: [PATCH 0096/1816] ACPI: processor: finish unifying
arch_acpi_processor_init_pdc()
The only thing arch-specific about calling _PDC is what bits get
set in the input obj_list buffer.
There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

Subject: [PATCH 0097/1816] ACPI: processor: unify
arch_acpi_processor_cleanup_pdc
The x86 and ia64 implementations of the function in $subject are
exactly the same.
Also, since the arch-specific implementations of setting _PDC have
been completely hollowed out, remove the empty shells.

Subject: [PATCH 0098/1816] ACPI: processor: introduce
acpi_processor_alloc_pdc()
acpi_processor_init_pdc() isn't really doing anything interesting
with the struct acpi_processor * parameter. Its real job is to allocate
the buffer for the _PDC bits.
So rename the function to acpi_processor_alloc_pdc(), and just return
the struct acpi_object_list * it's supposed to allocate.

Subject: [PATCH 0101/1816] ACPI: processor: change acpi_processor_set_pdc()
interface
When calling _PDC, we really only need the handle to the processor
to call the method; we don't look at any other parts of the
struct acpi_processor * given to us.
In the early path, when we walk the namespace, we are given the
handle directly, so just pass it through to acpi_processor_set_pdc()
without stuffing it into a wasteful struct acpi_processor allocated
on the stack each time
This saves 2834 bytes of stack.
Update the interface accordingly.

Subject: [PATCH 0104/1816] ARM: 5849/1: ARMv7: fix Oprofile events count
On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.
The PMNC_D bit should not be set, this patch fixes it.

Subject: [PATCH 0109/1816] arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.c: avoid
cross-CPU interrupts by using smp_call_function_any()
Presently acpi-cpufreq will perform the MSR read on the first CPU in the
mask. That's inefficient if that CPU differs from the current CPU.
Because we have to perform a cross-CPU call, but we could have run the
rdmsr on the current CPU.
So switch to using the new smp_call_function_any(), which will perform the
call on the current CPU if that CPU is present in the mask (it is).

Subject: [PATCH 0115/1816] ext4, jbd2: Add barriers for file systems with
exernal journals
This is a bit complicated because we are trying to optimize when we
send barriers to the fs data disk. We could just throw in an extra
barrier to the data disk whenever we send a barrier to the journal
disk, but that's not always strictly necessary.
We only need to send a barrier during a commit when there are data
blocks which are must be written out due to an inode written in
ordered mode, or if fsync() depends on the commit to force data blocks
to disk. Finally, before we drop transactions from the beginning of
the journal during a checkpoint operation, we need to guarantee that
any blocks that were flushed out to the data disk are firmly on the
rust platter before we drop the transaction from the journal.
Thanks to Oleg Drokin for pointing out this flaw in ext3/ext4.

Subject: [PATCH 0117/1816] ext4: Eliminate potential double free on error path
b_entry_name and buffer are initially NULL, are initialized within a loop
to the result of calling kmalloc, and are freed at the bottom of this loop.
The loop contains gotos to cleanup, which also frees b_entry_name and
buffer. Some of these gotos are before the reinitializations of
b_entry_name and buffer. To maintain the invariant that b_entry_name and
buffer are NULL at the top of the loop, and thus acceptable arguments to
kfree, these variables are now set to NULL after the kfrees.
This seems to be the simplest solution. A more complicated solution
would be to introduce more labels in the error handling code at the end of
the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>

Subject: [PATCH 0118/1816] fs-writeback: Add helper function to start
writeback if idle
ext4, at least, would like to start pushing on writeback if it starts
to get close to ENOSPC when reserving worst-case blocks for delalloc
writes. Writing out delalloc data will convert those worst-case
predictions into usually smaller actual usage, freeing up space
before we hit ENOSPC based on this speculation.
Thanks to Jens for the suggestion for the helper function,
& the naming help.
I've made the helper return status on whether writeback was
started even though I don't plan to use it in the ext4 patch;
it seems like it would be potentially useful to test this
in some cases.

Subject: [PATCH 0119/1816] ext4: flush delalloc blocks when space is low
Creating many small files in rapid succession on a small
filesystem can lead to spurious ENOSPC; on a 104MB filesystem:
for i in `seq 1 22500`; do
echo -n > $SCRATCH_MNT/$i
echo XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX > $SCRATCH_MNT/$i
done
leads to ENOSPC even though after a sync, 40% of the fs is free
again.
This is because we reserve worst-case metadata for delalloc writes,
and when data is allocated that worst-case reservation is not
usually needed.
When freespace is low, kicking off an async writeback will start
converting that worst-case space usage into something more realistic,
almost always freeing up space to continue.
This resolves the testcase for me, and survives all 4 generic
ENOSPC tests in xfstests.
We'll still need a hard synchronous sync to squeeze out the last bit,
but this fixes things up to a large degree.

Subject: [PATCH 0128/1816] SYSCTL: Print binary sysctl warnings (nearly) only
once
When printing legacy sysctls print the warning message
for each of them only once. This way there is a guarantee
the syslog won't be flooded for any sane program.
The original attempt at this made the tables non const and stored
the flag inline.
Linus suggested using a separate hash table for this, this is based on a
code snippet from him.
The hash implies this is not exact and can sometimes not print a
new sysctl due to a hash collision, but in practice this should not
be a problem
I used a FNV32 hash over the binary string with a 32byte bitmap. This
gives relatively little collisions when all the predefined binary sysctls
are hashed:
size 256
bucket
length number
0: [25]
1: [67]
2: [88]
3: [47]
4: [22]
5: [6]
6: [1]
The worst case is a single collision of 6 hash values.

Subject: [PATCH 0129/1816] SYSCTL: Add a mutex to the page_alloc zone order
sysctl
The zone list code clearly cannot tolerate concurrent writers (I couldn't
find any locks for that), so simply add a global mutex. No need for RCU
in this case.

Executing _OSC returns a buffer, which has an acpi object in it.
Don't directly returns the buffer, instead, we return the acpi object's
buffer. This fixes a regression since caller of acpi_run_osc expects
an acpi object's buffer returned.

Subject: [PATCH 0132/1816] Revert "x86, ucode-amd: Ensure ucode update on
suspend/resume after CPU off/online cycle"
This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425. It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.
As Rafael says:
"... it causes microcode_init_cpu() to be called during resume even for
CPUs for which there's no microcode to apply. That, in turn, results
in executing request_firmware() (on Intel CPUs at least) which doesn't
work at this stage of resume (we have device interrupts disabled, I/O
devices are still suspended and so on).
If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
known to us" , so before commit 9f15226e755 microcode_resume_cpu() was
called for all CPUs already in the system during suspend, which was
the right thing to do. The commit changed it so that the CPUs without
microcode to apply are now treated as "unknown", which is not quite
right.
The problem this commit attempted to solve has to be handled
differently."

Subject: [PATCH 0134/1816] i2c-omap: Don't write IE state in unidle if 0
Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer
to support off-mode) introduced a change which make the dev->iestate
contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle
is called. Previously, the state was only written if it wasn't equal
to zero.
In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),
in which case dev->iestate has not yet been initialized and will be set
to zero. Having this value written to the registers causes deadlock
while booting.
As such, this change restores the original functionality.

Subject: [PATCH 0135/1816] i2c-omap: OMAP3: Fix I2C lockup during
timeout/error cases
Current OMAP3 I2C driver code does not follow the correct sequence for soft
reset. Due to this, lock up issues are reported during timeout/error cases.
This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM
for soft reset. As per TRM, I2C controller needs to be disabled as a first
step during soft reset.
Here is correct soft reset sequence:
a. Ensure that the module is disabled
(clear the I2Ci.I2C_CON[15] I2C_EN bit to 0).
b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1.
c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1.
d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to
indicate the software reset is complete.
Tested on Zoom2, Zoom3, 3430SDP and 3630SDP

From ff3b00a0fcaab89ff885e9f0f4ad83c4ced788f4 Mon Sep 17 00:00:00 2001
From: Steve Hodgson <shodgson@solarflare.com>
Date: Wed, 23 Dec 2009 13:46:36 +0000
Subject: [PATCH 0139/1816] sfc: Move PHY software state initialisation from
init() into probe()
This prevents efx->link_advertising from being blatted during
a reset.
The phy_short_reach sysfs node is now destroyed later in the
port shutdown process, so check for STATE_RUNNING after
acquiring the rtnl_lock (just like in set_phy_flash_cfg).

From a355020af415947c7dee7e00a91360d11b6a9b47 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Wed, 23 Dec 2009 13:46:47 +0000
Subject: [PATCH 0140/1816] sfc: Include XGXS in XMAC link status check except
in XGMII loopback
The XGXS block may not get a link immediately in XGXS or XAUI loopback
modes, so we still need to check it. Split falcon_xaui_link_ok() into
falcon_xgxs_link_ok(), which checks only the Falcon XGXS block, and
falcon_xmac_link_ok(), which checks one or both sides of the link as
appropriate. Also rename falcon_check_xaui_link() to
falcon_xmac_link_ok_retry().

which usually unsticks it.

Subject: [PATCH 0143/1816] sfc: QT2025C: Switch into self-configure mode when
not in loopback
The PHY boots in a mode which is not necessarily optimal. This change
switches it to self-configure mode (except when in loopback, which
won't work in that mode if an SFP+ module is not present) by rebooting
the PHY's microcontroller, and replicating the sequence of configuration
writes from the boot EEPROM with the appropriate changes.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SN06 makes sure we get back a longer buffer which seems to be necessary
going forward as the SNC devices describes more and more devices (or
features more precisely). Moreover SN06 should be called with only the
descriptor offset to make sure we hit the rfkill controlling function
(F124 or F135) with a 0 argument to get a full list of features.

This change resolves an issue seen in some configurations where the link
may drop to 100Mb/s even though the link itself supports 1000Mb/s. The
issue was root caused to the fact that we were only trying the link once.
Now instead we will try up to 5 attempts on a faulty cable before
downshifting to 100Mb/s.

Subject: [PATCH 0157/1816] ACPI: do not select ACPI_DOCK from ATA_ACPI
In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.
However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43
("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.
This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

Subject: [PATCH 0160/1816] acerhdf: limit modalias matching to supported
BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T). This is not
fatal but worries users that see this message. Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.

Subject: [PATCH 0163/1816] ixgbe: fix Need to call pci_save_state after
pci_restore_state
This patch adds a pci_save_state() call in ixgbe_resume() after
pci_restore_state(). A similar change was made in ixgbe_io_slot_reset()
that accommodates pci_restore_state() new behavior. This change makes
pci_restore_state() clear the saved_state flag This is necessary due
to a resent kernel change to pci_restore_state() so that it now clears
the saved_state flag of the device right after the device.s standard
configuration registers have been poplulated with the previously saved
values.

API that accomplishes the same thing. As such, this converts the
remaining sh-sci straggles over, which enables the driver to be wired up
for ARM SH-Mobile CPUs as well.

Subject: [PATCH 0169/1816] net/via-rhine: Fix scheduling while atomic bugs
There are BUGs "scheduling while atomic" triggered by the timer
rhine_tx_timeout(). They are caused by calling napi_disable() (with
msleep()). This patch fixes it by moving most of the timer content to
the workqueue function (similarly to other drivers, like tg3), with
spin_lock() changed to BH version.
Additionally, there is spin_lock_irq() moved in rhine_close() to
exclude napi_disable() etc., also tg3's way.

Subject: [PATCH 0172/1816] pktgen: ndo_start_xmit can return NET_XMIT_xxx
values
This updates pktgen so that it does not decrement skb->users
when it receives valid NET_XMIT_xxx values. These are now
valid return values from ndo_start_xmit in net-next-2.6.
They also indicate the skb has been consumed.
This fixes pktgen to work correctly with vlan devices.

Subject: [PATCH 0173/1816] sh: Ensure all PG_dcache_dirty pages are written
back.
With some of the cache rework an address aliasing optimization was added,
but this managed to fail on certain mappings resulting in pages with
PG_dcache_dirty set never writing back their dcache lines. This patch
reverts to the earlier behaviour of simply always writing back when the
dirty bit is set.

Subject: [PATCH 0175/1816] amd64_edac: fix K8 chip select reporting
Fix the case when amd64_debug_display_dimm_sizes() reports only half the
amount of DRAM on it because it doesn't account for when the single DCT
operates in 128-bit mode and merges chip selects from different DIMMs.

Subject: [PATCH 0177/1816] amd64_edac: make driver loading more robust
Currently, the module does not initialize fully when the DIMMs aren't
ECC but remains still loaded. Propagate the error when no instance of
the driver is properly initialized and prevent further loading.
Reorganize and polish error handling in amd64_edac_init() while at it.

From 382b4480ff832e472d76c99f3f75fffb30e118c0 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Thu, 24 Dec 2009 12:52:44 +0000
Subject: [PATCH 0184/1816] ARM: footbridge: trim down old ISA rtc setup
This fixes a "start_kernel(): bug: interrupts were enabled early".
rtc_cmos now takes care of initializing the ISA RTC and reading the
current time and date from it; there's no need to repeat that here,
thereby causing interrupts to be enabled too early.

We used to make kseriod freezable to prevent unnecessary attempts at
resuming keyboard and mouse before taking hibernation image when suspend
and hibernation were sharing PM operations. Now that they are separated
and we don't risk resuming during 'thaw' we don't need to freeze kseriod
anymore. This will allow us to start resetting mouse and keyboard a bit
earlier, before rest of the userspace comes back up.

Subject: [PATCH 0195/1816] Input: ff-memless - another fix for signed to
unsigned overflow
The commit 9e68177ef93b2f34eee5a1e1707bceef4b9ba69c changed 'gain' from
signed to unsigned to fix an issue with rumble effect calculation, however
it introduced problems when calculating constant effects. Having 'gain'
being unsigned int was an unfortunate choice since it dominates all
implicit type conversions causing everything to be treated as unsigned
int.
Let's change it back to signed int and simply add proper casts to rumble
effect calculations.

Subject: [PATCH 0198/1816] Input: matrix-keypad - handle cases when GPIOs
can't be wakeup sources
On certain boards not all GPIOs may be used as wakeup sources, in which
case some of enable_irq_wake() calls will fail. On resume calling
disable_irq_wake() will warn about unbalanced IRQ wake disable.
Solve this by checking whether enable_irq_wake() succeeded or not and
no not call disable_irq_wake() for these GPIOs/IRQs that have not been
enabled.

Subject: [PATCH 0200/1816] ALSA: hda - HDMI sticky stream tag support
When we run the following commands in turn (with
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),
speaker-test -Dhw:0,3 -c2 -twav # HDMI
speaker-test -Dhw:0,0 -c2 -twav # Analog
The second command will produce sound in the analog lineout _as well as_
HDMI sink. The root cause is, device 0 "reuses" the same stream tag that
was used by device 3, and the "intelhdmi - sticky stream id" patch leaves
the HDMI codec in a functional state. So the HDMI codec happily accepts
the audio samples which reuse its stream tag.
The proposed solution is to remember the last device each azx_dev was
assigned to, and prefer to
1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used
2) or assign a never-used azx_dev for HDMI
With this patch and the above two speaker-test commands,
HDMI codec will use stream tag 8 and Analog codec will use 5.
The stream tag used by HDMI codec won't be reused by others, as long
as we don't run out of the 4 playback azx_dev's. The legacy Analog
codec will continue to use stream tag 5 because its device id is 0
(this is a bit tricky).

When ext4_da_writepages increases the nr_to_write in writeback_control
then it must always re-base the return value. Originally there was a
(misguided) attempt prevent wbc.nr_to_write from going negative. In
fact, it's necessary to allow nr_to_write to be negative so that
wb_writeback() can correctly calculate how many pages were actually
written.

Subject: [PATCH 0202/1816] ALSA: hda - Disable tigger at pin-sensing on AD
codecs
Analog Device codecs seem to have problems with the triggering of
pin-sensing although their pincaps give the trigger requirements.
Some reported that constant CPU load on HP laptops with AD codecs.
For avoiding this regression, add a flag to codec struct to notify
explicitly that the codec doesn't suppot the trigger at pin-sensing.

Subject: [PATCH 0204/1816] x86, compress: Force i386 instructions for the
decompressor
Recently, some distros have started shipping versions of gcc which
default to -march=i686. This breaks building kernels for pre-i686
machines, even if they have been selected in Kconfig, due to the
generation of CMOV instructions.
There isn't enough benefit to try to preserve the generation of these
instructions even when selected, so simply force -march=i386 for the
decompressor when building a 32-bit kernel.

Subject: [PATCH 0206/1816] net: restore ip source validation
when using policy routing and the skb mark:
there are cases where a back path validation requires us
to use a different routing table for src ip validation than
the one used for mapping ingress dst ip.
One such a case is transparent proxying where we pretend to be
the destination system and therefore the local table
is used for incoming packets but possibly a main table would
be used on outbound.
Make the default behavior to allow the above and if users
need to turn on the symmetry via sysctl src_valid_mark

ALSA: AACI: factor common hw_params logic into aaci_pcm_hw_params [1]
by adding/moving the aaci struct to the right position.
The patch mentioned above merged common source parts into one function,
but unfortunately left out the aaci struct and consequently caused a
build failure e.g. for arm versatile_config [2]

Subject: [PATCH 0212/1816] thinkpad-acpi: make volume subdriver optional
Allow the user to choose through Kconfig if the Console Audio Control
interface (aka "volume subdriver") should be available or not.
This not only saves some memory, but also allows the thinkpad-acpi
driver to be built-in even if ALSA is modular when the console audio
control interface is not wanted.
This change fixes a build problem that is causing some annoyances, in
a way that doesn't disable the entire driver on kernels without ALSA
support.

-mute/unmute control. The available commands are:
+
+About the ThinkPad Console Audio control:
+
+ThinkPads have a built-in amplifier and muting circuit that drives the
+console headphone and speakers. This circuit is after the main AC97
+or HDA mixer in the audio path, and under exclusive control of the
+firmware.
+
+ThinkPads have three special hotkeys to interact with the console
+audio control: volume up, volume down and mute.
+
+It is worth noting that the normal way the mute function works (on
+ThinkPads that do not have a "mute LED") is:
+
+1. Press mute to mute. It will *always* mute, you can press it as
+ many times as you want, and the sound will remain mute.
+
+2. Press either volume key to unmute the ThinkPad (it will _not_
+ change the volume, it will just unmute).
+
+This is a very superior design when compared to the cheap software-only
+mute-toggle solution found on normal consumer laptops: you can be
+absolutely sure the ThinkPad will not make noise if you press the mute
+button, no matter the previous state.
+
+The IBM ThinkPads, and the earlier Lenovo ThinkPads have variable-gain
+amplifiers driving the speakers and headphone output, and the firmware
+also handles volume control for the headphone and speakers on these
+ThinkPads without any help from the operating system (this volume
+control stage exists after the main AC97 or HDA mixer in the audio
+path).
+
+The newer Lenovo models only have firmware mute control, and depend on
+the main HDA mixer to do volume control (which is done by the operating
+system). In this case, the volume keys are filtered out for unmute
+key press (there are some firmware bugs in this area) and delivered as
+normal key presses to the operating system (thinkpad-acpi is not
+involved).
+
+
+The ThinkPad-ACPI volume control:
+
+The preferred way to interact with the Console Audio control is the
+ALSA interface.
+
+The legacy procfs interface allows one to read the current state,
+and if volume control is enabled, accepts the following commands:

This is because ucc_geth_tx() tries to process an empty queue when
queues are logically stopped. Stopping the queues doesn't disable
polling, and since nowadays ucc_geth_tx() is actually called from
the polling routine, the oops above might pop up.
Fix this by removing 'netif_queue_stopped() == 0' check.

If PHY doesn't have an IRQ, phylib would poll for link changes, and
would call adjust_link() every second. In that case we disable and
enable the controller every second.
Let's better check if there is actually anything changed, and, if so,
change the MAC settings.

The gfar_select_queue() function was used to set queue mapping
only for forwarding/bridging applications and the condition
for locally generated packets was completely ignored.
The solution is to remove the gfar_select_queue() function and
use skb_record_rx_queue to set queue mapping for
forwarding/bridging applications. This will ensure that in case of
forwarding/bridging applications txq = rxq will be selected and
skb_tx_hash will be used to pick up a txq for locally generated packets.

Subject: [PATCH 0225/1816] KVM: MMU: remove prefault from invlpg handler
The invlpg prefault optimization breaks Windows 2008 R2 occasionally.
The visible effect is that the invlpg handler instantiates a pte which
is, microseconds later, written with a different gfn by another vcpu.
The OS could have other mechanisms to prevent a present translation from
being used, which the hypervisor is unaware of.
While the documentation states that the cpu is at liberty to prefetch tlb
entries, it looks like this is not heeded, so remove tlb prefetch from
invlpg.

The other one is in kvm_vm_ioctl_assign_device(), which take kvm->slots_lock
first, then kvm->lock.
Update the comment of lock order as well.
Observe it due to kernel locking debug warnings.

arch/ia64/kvm/vmm.c:70: error: 'spinlock_t' has no member named 'raw_lock'
KVM has it's own spinlock routines. It should not depend on the base kernel
spinlock_t type (which changed when ia64 switched to ticket locks). Define
its own vmm_spinlock_t type.

Subject: [PATCH 0230/1816] KVM: powerpc: Fix mtsrin in book3s_64 mmu
We were shifting the Ks/Kp/N bits one bit too far on mtsrin. It took
me some time to figure that out, so I also put in some debugging and a
comment explaining the conversion.
This fixes current OpenBIOS boot on PPC64 KVM.

Subject: [PATCH 0235/1816] x86: Use KERN_DEFAULT log-level in __show_regs()
Andrew Morton reported a strange looking kmemcheck warning:
WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88004fba6c20)
0000000000000000310000000000000000000000000000002413000000c9ffff

[<ffffffff81003074>] kernel_thread_helper+0x4/0x10
[<ffffffffffffffff>] 0xffffffffffffffff
The above printout is missing register dump completely. The
problem here is that the output comes from syslog which doesn't
show KERN_INFO log-level messages. We didn't see this before
because both of us were testing on 32-bit kernels which use the
_default_ log-level.
Fix that up by explicitly using KERN_DEFAULT log-level for
__show_regs() printks.

Subject: [PATCH 0236/1816] kprobes: Fix distinct type warning
Every time I see this:
kernel/kprobes.c: In function 'register_kretprobe':
kernel/kprobes.c:1038: warning: comparison of distinct pointer types lacks a cast
I'm wondering if something changed in common code and we need to
do something for s390. Apparently that's not the case.
Let's get rid of this annoying warning.

Subject: [PATCH 0244/1816] SLAB: Fix lockdep annotation breakage
Commit ce79ddc8e2376a9a93c7d42daf89bfcbb9187e62 ("SLAB: Fix lockdep annotations
for CPU hotplug") broke init_node_lock_keys() off-slab logic which causes
lockdep false positives.
Fix that up by reverting the logic back to original while keeping CPU hotplug
fixes intact.

Subject: [PATCH 0245/1816] sh: Only provide a PCLK definition for legacy CPG
CPUs.
As CPUs are migrated over to more fully-featured clock frameworks of
their own and off of the legacy CPG code, they no longer have any real
need for defining the PCLK value. The PCLK define in itself is already
fairly misleading, as many boards get their input clocks from different
sources, making this value fairly arbitrary anyways.
Outside of the legacy CPG clock framework, the only place where this
value is used is for deriving CLOCK_TICK_RATE, which we set back to the
legacy PIT value that it was before the PCLK definitions were added in
the first place.

Subject: [PATCH 0246/1816] x86: SGI UV: Fix writes to led registers on remote
uv hubs
The wrong address was being used to write the SCIR led regs on
remote hubs. Also, there was an inconsistency between how BIOS
and the kernel indexed these regs. Standardize on using the
lower 6 bits of the APIC ID as the index.
This patch fixes the problem of writing to an errant address to
a cpu # >= 64.

Subject: [PATCH 0257/1816] block: Fix incorrect alignment offset reporting and
update documentation
queue_sector_alignment_offset returned the wrong value which caused
partitions to report an incorrect alignment_offset. Since offset
alignment calculation is needed several places it has been split into a
separate helper function. The topology stacking function has been
updated accordingly.
Furthermore, comments have been added to clarify how the stacking
function works.

Subject: [PATCH 0262/1816] firewire: fix use of multiple AV/C devices, allow
multiple FCP listeners
Control of more than one AV/C device at once --- e.g. camcorders, tape
decks, audio devices, TV tuners --- failed or worked only unreliably,
depending on driver implementation. This affected kernelspace and
userspace drivers alike and was caused by firewire-core's inability to
accept multiple registrations of FCP listeners.
The fix allows multiple address handlers to be registered for the FCP
command and response registers. When a request for these registers is
received, all handlers are invoked, and the Firewire response is
generated by the core and not by any handler.
The cdev API does not change, i.e., userspace is still expected to send
a response for FCP requests; this response is silently ignored.

Subject: [PATCH 0264/1816] firewire: ohci: always use packet-per-buffer mode
for isochronous reception
This is a minimal change meant for the short term: Never set the
ohci->use_dualbuffer flag to true.
There are two reasons to do so:
- Packet-per-buffer mode and dual-buffer mode do not behave the same
under certain circumstances, notably if several packets are covered
by a single fw_cdev_iso_packet descriptor.
http://marc.info/?l=linux1394-devel&m=124965653718313
Therefore the driver stack should not silently choose one or the
other mode but should leave the choice to the high-level driver
(regardless if kernel driver or userspace driver). Or simply always
only offer packet-per-buffer mode, since a considerable number of
controllers, even current ones, does not offer dual-buffer support.
- Even under circumstances where packet-per-buffer mode and
dual-buffer mode behave exactly the same --- notably when used
through libraw1394, libdc1394, as well as the current two kernel
drivers which use isochronous reception (firewire-net and firedtv)
--- we are still faced with the problem that several OHCI 1.1
controllers have bugs in dual-buffer mode. Although it looks like
we have identified most of those buggy controllers by now, we
cannot be quite sure about that.
So, use packet-per-buffer by default from now on. This change should
be followed up by a more complete solution: Either extend the
in-kernel API and the userspace ABI by a choice between the two IR modes
or remove all dual-buffer related code from firewire-ohci.

Linux 1394 project is http://ieee1394.wiki.kernel.org/.
The classic drivers/ieee1394/ stack is now obsolete from the development
point of view, though still a useful alternative in productive use. But
nobody should attempt to submit style cleanup patches for it or to
develop new drivers on top of this stack, hence mark its MAINTAINERS
entry as Obsolete.
drivers/ieee1394/raw1394*, like the rest of the old stack, does not
receive bigger code changes anymore, hence shrink the MAINTAINERS
database a bit by dropping raw1394's special entry. If something
important and urgent is going to come up for raw1394, I will make sure
that Dan will be notified of it besides via linux1394-devel.

Subject: [PATCH 0266/1816] firewire, ieee1394: update Kconfig help
Update the Kconfig help texts of both stacks to encourage a general move
from the older to the newer drivers. However, do not label ieee1394 as
"Obsolete" yet, as the newer drivers have not been deployed as default
stack in the majority of Linux distributions yet, and those who start
doing so now may still want to install the old drivers as fallback for
unforeseen issues.
Since Linux 2.6.32, FireWire audio devices can be driven by the newer
firewire driver stack too, hence remove an outdated comment about audio
devices. Also remove comments about library versions since the 2nd
generation of libraw1394 and libdc1394 is now in common use; details on
library versions can be read at the wiki link from the help texts.

Commit 500f5a0bf5f0624dae34307010e240ec090e4cde
(reiserfs: Fix possible recursive lock) fixed a vmalloc under reiserfs
lock that triggered a lockdep warning because of a
IN-FS-RECLAIM <-> RECLAIM-FS-ON locking dependency inversion.
But this patch has ommitted another vmalloc call in the same path
that allocates the journal. Relax the lock for this one too.

Subject: [PATCH 0268/1816] md: Fix unfortunate interaction with evms
evms configures md arrays by:
open device
send ioctl
close device
for each different ioctl needed.
Since 2.6.29, the device can disappear after the 'close'
unless a significant configuration has happened to the device.
The change made by "SET_ARRAY_INFO" can too minor to stop the device
from disappearing, but important enough that losing the change is bad.
So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device
active as long as ctime is non-zero (it gets zeroed with lots of other
things when the array is stopped).
This is suitable for -stable kernels since 2.6.29.

Subject: [PATCH 0269/1816] md: fix small irregularity with start_ro module
parameter
The start_ro modules parameter can be used to force arrays to be
started in 'auto-readonly' in which they are read-only until the first
write. This ensures that no resync/recovery happens until something
else writes to the device. This is important for resume-from-disk
off an md array.
However if an array is started 'readonly' (by writing 'readonly' to
the 'array_state' sysfs attribute) we want it to be really 'readonly',
not 'auto-readonly'.
So strengthen the condition to only set auto-readonly if the
array is not already read-only.

Subject: [PATCH 0272/1816] md: allow a resync that is waiting for other resync
to complete, to be aborted.
If two arrays share a device, then they will not both resync at the
same time. One will wait for the other to complete.
While waiting, the MD_RECOVERY_INTR flag is not checked so a device
failure, which would make the resync pointless, does not cause the
resync to abort, so the failed device cannot be removed (as it cannot
be remove while a resync is happening).
So add a test for MD_RECOVERY_INTR.

Subject: [PATCH 0273/1816] ext4: Ensure zeroout blocks have no dirty metadata
This fixes a bug (found by Curt Wohlgemuth) in which new blocks
returned from an extent created with ext4_ext_zeroout() can have dirty
metadata still associated with them.

Subject: [PATCH 0274/1816] ACPI: fix ACPI=n allmodconfig build
Today's -tip failed to build because commit
9e368fa011d4e0aa050db348d69514900520e40b ("ipmi: add PNP discovery (ACPI
namespace via PNPACPI)") from today's upstream kernel causes the following
build failure on x86, for CONFIG_ACPI=n && CONFIG_IPMI_SI=y:
drivers/char/ipmi/ipmi_si_intf.c:3208: error: 'ipmi_pnp_driver' undeclared (first use in this function)
drivers/char/ipmi/ipmi_si_intf.c:3208: error: (Each undeclared identifier is reported only once
drivers/char/ipmi/ipmi_si_intf.c:3208: error: for each function it appears in.)
drivers/char/ipmi/ipmi_si_intf.c:3334: error: 'ipmi_pnp_driver' undeclared (first use in this function)
The reason is that the ipmi_pnp_driver depends on ACPI facilities and is only
made available under ACPI - while the registration and unregistration is made
dependent on CONFIG_PNP:
#ifdef CONFIG_PNP
pnp_register_driver(&ipmi_pnp_driver);
#endif
The solution is to only register this driver under ACPI. (Also, the CONFIG_PNP
dependency is not needed because pnp_register_driver() is stubbed out in the
!CONFIG_PNP case.)

wmi_get_event_data() return value
When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.
The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It would appear that in BIOS's with nVidia hooks, the GUID
05901221-D566-11D1-B2F0-00A0C9062910 is duplicated. For now, the simplest
solution is to just ignore any duplicate GUIDs. These particular hooks are not
currently supported/ used in the kernel, so whoever does that can figure out
what the 'right' solution should be (if there's a better one).

Subject: [PATCH 0293/1816] x86/agp: Fix agp_amd64_init() initialization with
CONFIG_GART_IOMMU enabled
with CONFIG_GART_IOMMU enabled drivers/char/agp/amd64-agp.c has:
#ifndef CONFIG_GART_IOMMU
module_init(agp_amd64_init);
module_exit(agp_amd64_cleanup);
#endif
agp_amd64_init() was called via gart_iommu_init with
CONFIG_GART_IOMMU=y agp_amd64_init() was called via module_init
with CONFIG_GART_IOMMU=n
The commit 75f1cdf1dda92cae037ec848ae63690d91913eac changes the
x86 dma initialization routine: gart_iommu_init() is called only
when GART IOMMU is detected. So when GART IOMMU isn't detected,
agp_amd64_init isn't called.
Marin Mitov reported this issue:
http://marc.info/?l=linux-kernel&m=126192729110083&w=2
With this patch, agp_amd64_init() is always called via
module_init (the above ifndef is removed). If agp_amd64_init()
is called via gart_iommu_init() earlier, agp_amd64_init()
finishes without doing anything (when it is called via
module_init).

Subject: [PATCH 0294/1816] tracing/kprobe: Show sign of fields in trace_kprobe
format files
The format files of trace_kprobe do not show the sign of the fields.
The other format files show the field signed type of the fields and
this patch makes the trace_kprobe formats consistent with the others.

Subject: [PATCH 0295/1816] tracing/syscalls: Fix typo in SYSCALL_DEFINE0
The struct syscall_metadata variable name in SYSCALL_DEFINE0
should be __syscall_meta__##sname instead of __syscall_meta_##sname
to match the name that is in SYSCALL_DEFINE1/2/3/4/5/6.
This error causes event_enter_##sname->data to point to the wrong
location, which causes syscalls which are defined by SYSCALL_DEFINE0()
not to be traced.

Subject: [PATCH 0298/1816] [SCSI] qla2xxx: Get the link data rate explicitly
during device resync.
When the hba port gets logged out of the fabric, or other
such transitional state when the physical link is still present,
the driver doesn't receive a loop up asyn event (where the link
data rate currently gets set). Hence send a explicit mailbox command
to get the link rate in such conditions.

Subject: [PATCH 0303/1816] [SCSI] pmcraid: fix to avoid twice scsi_dma_unmap
for a command
For a particular driver error condition, driver was doing double
scsi_dma_unmaps. Driver was calling scsi_dma_unmap in
pmcraid_error_handler and return 0. This pmcraid_error_handler is called
by pmcraid_io_done which will do scsi_dma_unmap again when it has
return 0 from pmcraid_error_handler.

Subject: [PATCH 0304/1816] ext4: Patch up how we claim metadata blocks for
quota purposes
As reported in Kernel Bugzilla #14936, commit d21cd8f triggered a BUG
in the function ext4_da_update_reserve_space() found in
fs/ext4/inode.c. The root cause of this BUG() was caused by the fact
that ext4_calc_metadata_amount() can severely over-estimate how many
metadata blocks will be needed, especially when using direct
block-mapped files.
In addition, it can also badly *under* estimate how much space is
needed, since ext4_calc_metadata_amount() assumes that the blocks are
contiguous, and this is not always true. If the application is
writing blocks to a sparse file, the number of metadata blocks
necessary can be severly underestimated by the functions
ext4_da_reserve_space(), ext4_da_update_reserve_space() and
ext4_da_release_space(). This was the cause of the dq_claim_space
reports found on kerneloops.org.
Unfortunately, doing this right means that we need to massively
over-estimate the amount of free space needed. So in some cases we
may need to force the inode to be written to disk asynchronously in
to avoid spurious quota failures.

Subject: [PATCH 0306/1816] libsrp: fix compile failure
commit 45465487897a1c6d508b14b904dc5777f7ec7e04 ("kfifo: move struct
kfifo in place") caused a compile failure in ibmvscsitgt.c because it
changed a pointer to kfifo in the libsrp.h structure to a direct
inclusion without including <linux/kfifo.h>.
The fix is simple, just add the include, but how did this happen? This
change, introduced at -rc2, hardly looks like a bug fix, and it clearly
didn't go through linux-next, which would have picked up this compile
failure (it only occurs on ppc because of the ibm virtual scsi target).
[ Apparently all of -mm wasn't in linux-next.. ]

Subject: [PATCH 0307/1816] mm: move sys_mmap_pgoff from util.c
Move sys_mmap_pgoff() from mm/util.c to mm/mmap.c and mm/nommu.c,
where we'd expect to find such code: especially now that it contains
the MAP_HUGETLB handling. Revert mm/util.c to how it was in 2.6.32.
This patch just ignores MAP_HUGETLB in the nommu case, as in 2.6.32,
whereas 2.6.33-rc2 reported -ENOSYS. Perhaps validate_mmap_request()
should reject it with -EINVAL? Add that later if necessary.

Subject: [PATCH 0308/1816] x86_64 SGI UV: Fix writes to led registers on
remote uv hubs.
The wrong address was being used to write the SCIR led regs on remote
hubs. Also, there was an inconsistency between how BIOS and the kernel
indexed these regs. Standardize on using the lower 6 bits of the APIC
ID as the index.
This patch fixes the problem of writing to an errant address to a
cpu # >= 64.

From: "Serge E. Hallyn" <serue@us.ibm.com>
Date: Tue, 29 Dec 2009 14:50:19 -0600
Subject: [PATCH 0309/1816] generic_permission: MAY_OPEN is not write access
generic_permission was refusing CAP_DAC_READ_SEARCH-enabled
processes from opening DAC-protected files read-only, because
do_filp_open adds MAY_OPEN to the open mask.
Ignore MAY_OPEN. After this patch, CAP_DAC_READ_SEARCH is
again sufficient to open(fname, O_RDONLY) on a file to which
DAC otherwise refuses us read permission.

Subject: [PATCH 0311/1816] dell-wmi: sys_init_module: 'dell_wmi'->init
suspiciously returned 21, it should follow 0/-E convention
wmi_install_notify_handler() returns an acpi_error,
but dell_wmi_init() needs return a -errno style error.

Subject: [PATCH 0314/1816] powerpc: Use scripts/mkuboot.sh instead of
'mkimage'
mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using
mkuboot.sh provides clearer error reporting and allows a toolchain to
use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage.
Additionally, this brings PowerPC in line with other architectures
which already call mkimage via mkuboot.sh.

Subject: [PATCH 0315/1816] ACPI: introduce kernel parameter
acpi_sleep=sci_force_enable
Introduce kernel parameter acpi_sleep=sci_force_enable
some laptop requires SCI_EN being set directly on resume,
or else they hung somewhere in the resume code path.
We already have a blacklist for these laptops but we still need
this option, especially when debugging some suspend/resume problems,
in case there are systems that need this workaround and are not yet
in the blacklist.

2. the return value of function acpi_pad_idle_cpus is useless.
3. enhance the process of create_power_saving_task/destroy_power_saving_task
4. Add more error checks when evaluating _PUR object.

Subject: [PATCH 0317/1816] ACPI video: Prune dupe video devices, unless
"video.allow_duplicates"
Some buggy BIOS exports multiple ACPI video bus devices for the same
VGA controller, and multiple backlight control methods as well.
This messes up the ACPI video backlight control.
http://bugzilla.kernel.org/show_bug.cgi?id=13577
With this patch applied, only the FIRST ACPI video bus device
under a PCI device node is bind to ACPI video driver by default.
If the first ACPI video bus device doesn't work well, we can use
video.allow_duplicates=1 to go back to the old behavior.

[...]
Here is why.
On suspend:
- PM core starts suspending devices, ucc_geth_suspend gets called;
- ucc_geth calls phy_stop() on suspend. Note that phy_stop() is
mostly asynchronous so it doesn't block ucc_geth's suspend routine,
it just sets PHY_HALTED state and disables PHY's interrupts;
- Suddenly the state machine gets scheduled, it grabs the phydev->lock
mutex and tries to process the PHY_HALTED state, so it calls
phydev->adjust_link(phydev->attached_dev). In ucc_geth case
adjust_link() calls msleep(), which reschedules the code flow back to
PM core, which now finishes suspend and so we end up sleeping with
phydev->lock mutex held.
On resume:
- PM core starts resuming devices (notice that nobody rescheduled
the state machine yet, so the mutex is still held), the core calls
ucc_geth's resume routine;
- ucc_geth_resume restarts the PHY with phy_stop()/phy_start()
sequence, and the phy_*() calls are trying to grab the phydev->lock
mutex. Here comes the deadlock.
This patch fixes the issue by stopping the state machine on suspend
and starting it again on resume.

Subject: [PATCH 0320/1816] phylib: Properly reinitialize PHYs after
hibernation
Since hibernation assumes power loss, we should fully reinitialize
PHYs (including platform fixups), as if PHYs were just attached.
This patch factors phy_init_hw() out of phy_attach_direct(), then
converts mdio_bus to dev_pm_ops and adds an appropriate restore()
callback.

We use a rather complicated logic to support eTSEC and eTSEC2.0
registers maps in a single driver. Currently, the code tries to
unmap 'regs', but for non-eTSEC2.0 controllers 'regs' doesn't
point to a mapping start, and this might cause badness on probe
failure or module removal:

Subject: [PATCH 0324/1816] perf: Pass appropriate frame pointer to
dump_trace()
Pass the frame pointer from the regs of the interrupted path
to dump_trace() while processing the stack trace.
Currently, dump_trace() takes the current bp and starts the
callchain from dump_trace() itself. This is wasteful because
we need to walk through the entire NMI/DEBUG stack before
retrieving the interrupted point.
We can fix that by just using the frame pointer from the
captured regs. It points exactly where we want to start.

Subject: [PATCH 0325/1816] perf: Fix NULL deref in inheritance code
Liming found a NULL deref when a task has a perf context but no
counters when it forks.
This can occur in two cases, a race during construction where
the fork hits after installing the context but before the first
counter gets inserted, or more reproducably, a fork after the
last counter is closed (which leaves the context around).

Stephen Rothwell reported the following build warning:
lib/dma-debug.c: In function 'dma_debug_device_change':
lib/dma-debug.c:680: warning: 'return' with no value, in function returning non-void
Introduced by commit f797d9881b62c2ddb1d2e7bd80d87141949c84aa
("dma-debug: Do not add notifier when dma debugging is disabled").
Return 0 [notify-done] when disabled. (this is standard bus notifier behavior.)

Subject: [PATCH 0327/1816] PCI: Fix build if quirks are not enabled
After commit b9c3b266411d27f1a6466c19d146d08db576bfea ("PCI: support
device-specific reset methods") the kernel build is broken if
CONFIG_PCI_QUIRKS is unset.
Fix this by moving pci_dev_specific_reset() to drivers/pci/quirks.c and
providing an empty replacement for !CONFIG_PCI_QUIRKS builds.

Introduced by commit 5b889bf23 ("PCI: Fix build if quirks are not

'const', but didn't then change the code to match, and use a const
pointer when moving it to quirks.c.
Trivially fixed by just adding the required 'const' to the iterator
variable.

Subject: [PATCH 0331/1816] ext4: Calculate metadata requirements more
accurately
In the past, ext4_calc_metadata_amount(), and its sub-functions
ext4_ext_calc_metadata_amount() and ext4_indirect_calc_metadata_amount()
badly over-estimated the number of metadata blocks that might be
required for delayed allocation blocks. This didn't matter as much
when functions which managed the reserved metadata blocks were more
aggressive about dropping reserved metadata blocks as delayed
allocation blocks were written, but unfortunately they were too
aggressive. This was fixed in commit 0637c6f, but as a result the
over-estimation by ext4_calc_metadata_amount() would lead to reserving
2-3 times the number of pending delayed allocation blocks as
potentially required metadata blocks. So if there are 1 megabytes of
blocks which have been not yet been allocation, up to 3 megabytes of
space would get reserved out of the user's quota and from the file
system free space pool until all of the inode's data blocks have been
allocated.
This commit addresses this problem by much more accurately estimating
the number of metadata blocks that will be required. It will still
somewhat over-estimate the number of blocks needed, since it must make
a worst case estimate not knowing which physical blocks will be
needed, but it is much more accurate than before.

Subject: [PATCH 0332/1816] [ARM] pxa: do not enable L2 after MMU is enabled
Outer cache checked whether L2 is enabled or not. If L2 isn't enabled in XSC3,
it would enable L2. This operation is evil that would make system hang.
In XSC3 core document, these words are mentioned in below.
"Following reset, the L2 Unified Cache Enable bit is cleared. To enable the L2
Cache, software may set the bit to a '1' before or at the same time as enabling
the MMU. Enabling the L2 Cache after the MMU has been enabled or disabling the
L2 Cache after the L2 Cache has been enabled, may result in unpredictable
behavior of the processor."
When outer cache is initialized, the MMU is already enabled. We couldn't enable
L2 after MMU enabled.

Subject: [PATCH 0335/1816] reiserfs: Fix reiserfs lock <-> i_xattr_sem
dependency inversion
i_xattr_sem depends on the reiserfs lock. But after we grab
i_xattr_sem, we may relax/relock the reiserfs lock while waiting
on a freezed filesystem, creating a dependency inversion between
the two locks.
In order to avoid the i_xattr_sem -> reiserfs lock dependency, let's
create a reiserfs_down_read_safe() that acts like
reiserfs_mutex_lock_safe(): relax the reiserfs lock while grabbing
another lock to avoid undesired dependencies induced by the
heivyweight reiserfs lock.
This fixes the following warning:

Subject: [PATCH 0336/1816] reiserfs: Warn on lock relax if taken recursively
When we relax the reiserfs lock to avoid creating unwanted
dependencies against others locks while grabbing these,
we want to ensure it has not been taken recursively, otherwise
the lock won't be really relaxed. Only its depth will be decreased.
The unwanted dependency would then actually happen.
To prevent from that, add a reiserfs_lock_check_recursive() call
in the places that need it.

Subject: [PATCH 0337/1816] reiserfs: Fix reiserfs lock <-> i_mutex dependency
inversion on xattr
While deleting the xattrs of an inode, we hold the reiserfs lock
and grab the inode->i_mutex of the targeted inode and the root
private xattr directory.
Later on, we may relax the reiserfs lock for various reasons, this
creates inverted dependencies.
We can remove the reiserfs lock -> i_mutex dependency by relaxing
the former before calling open_xa_dir(). This is fine because the
lookup and creation of xattr private directories done in
open_xa_dir() are covered by the targeted inode mutexes. And deeper
operations in the tree are still done under the write lock.
This fixes the following lockdep report:

Subject: [PATCH 0338/1816] reiserfs: Relax reiserfs lock while freeing the
journal
Keeping the reiserfs lock while freeing the journal on
umount path triggers a lock inversion between bdev->bd_mutex
and the reiserfs lock.
We don't need the reiserfs lock at this stage. The filesystem
is not usable anymore, and there are no more pending commits,
everything got flushed (even this operation was done in parallel
and didn't required the reiserfs lock from the current process).
This fixes the following lockdep report:

Subject: [PATCH 0339/1816] reiserfs: Relax lock before open xattr dir in
reiserfs_xattr_set_handle()
We call xattr_lookup() from reiserfs_xattr_get(). We then hold
the reiserfs lock when we grab the i_mutex. But later, we may
relax the reiserfs lock, creating dependency inversion between
both locks.
The lookups and creation jobs ar already protected by the
inode mutex, so we can safely relax the reiserfs lock, dropping
the unwanted reiserfs lock -> i_mutex dependency, as shown
in the following lockdep report:

Subject: [PATCH 0340/1816] reiserfs: Fix unwanted recursive reiserfs lock in
reiserfs_unlink()
reiserfs_unlink() may or may not be called under the reiserfs
lock.
But it also takes the reiserfs lock and can then acquire it
recursively which leads to do_journal_begin_r() that fails to
relax the reiserfs lock before grabbing the journal mutex,
creating an unexpected lock inversion.
We need to ensure reiserfs_unlink() won't get the reiserfs lock
recursively using reiserfs_write_lock_once().
This fixes the following warning that precedes a lock inversion
report (reiserfs lock <-> journal mutex).

this changes in the future for newer subtypes, this will have to be made
more fine-grained.

Subject: [PATCH 0354/1816] via-velocity: Give RX descriptors to the NIC later
on open or MTU change
velocity_open() calls velocity_give_many_rx_descs(), which gives RX
descriptors to the NIC, before installing an interrupt handler or
calling velocity_init_registers(). I think this is very unsafe and it
appears to explain the bug report <http://bugs.debian.org/508527>.
On MTU change, velocity_give_many_rx_descs() is again called before
velocity_init_registers(). I'm not sure whether this is unsafe but
it does look wrong.
Therefore, move the calls to velocity_give_many_rx_descs() after
request_irq() and velocity_init_registers().

Subject: [PATCH 0355/1816] rose_loopback_timer sets VC number <=
ROSE_DEFAULT_MAXVC
cat /proc/net/rose displayed a rose sockets abnormal lci value, i.e.
greater than maximum number of VCs per neighbour allowed.
This number prevents further test of lci value during rose operations.
Example (lines shortened) :
[bernard]# cat /proc/net/rose
dest_addr dest_call src_addr src_call dev lci neigh st vs vr va
* * 2080175520 F6BVP-1 rose0 000 00000 0 0 0 0
2080175520 FPAD-0 2080175520 WP-0 rose0 FFE 00001 3 0 0 0
Here are the default parameters :
linux/include/net/rose.h:#define ROSE_DEFAULT_MAXVC 50 /* Maximum number of VCs per neighbour */
linux/net/rose/af_rose.c:int sysctl_rose_maximum_vcs = ROSE_DEFAULT_MAXVC;
With the following patch, rose_loopback_timer() attributes a VC number
within limits.

Subject: [PATCH 0373/1816] [S390] qdio: convert global statistics to
per-device stats
Revamp the qdio performance statistics and move them from procfs to
debugfs using the seq_file interface. Since the statistics are not
intended for the general user the removal of /proc/qdio_perf should
not surprise anyone.
The per device statistics are disabled by default, writing 1 to
/<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the
statistics for the given device.

Subject: [PATCH 0376/1816] SECURITY: selinux, fix update_rlimit_cpu parameter
Don't pass current RLIMIT_RTTIME to update_rlimit_cpu() in
selinux_bprm_committing_creds, since update_rlimit_cpu expects
RLIMIT_CPU limit.
Use proper rlim[RLIMIT_CPU].rlim_cur instead to fix that.

Subject: [PATCH 0378/1816] resource: add helpers for fetching rlimits
We want to be sure that compiler fetches the limit variable only
once, so add helpers for fetching current and maximal resource
limits which do that.
Add them to sched.h (instead of resource.h) due to circular dependency
sched.h->resource.h->task_struct
Alternative would be to create a separate res_access.h or similar.

Subject: [PATCH 0386/1816] ARM: MX3: make CPU revision number detection work
on all boards
Commit 52939c03 (ARM: MX3: fix CPU revision number detection) started
using the CPU's SREV register for revision number detection. This
makes it mandatory to have a valid SPBA0 mapping. Add this to the
global map_io code instead of adding multiple copies for each board.

Subject: [PATCH 0388/1816] ipvs: Add boundary check on ioctl arguments
The ipvs code has a nifty system for doing the size of ioctl command
copies; it defines an array with values into which it indexes the cmd
to find the right length.
Unfortunately, the ipvs code forgot to check if the cmd was in the
range that the array provides, allowing for an index outside of the
array, which then gives a "garbage" result into the length, which
then gets used for copying into a stack buffer.
Fix this by adding sanity checks on these as well as the copy size.

Subject: [PATCH 0391/1816] [SCSI] stex: fix scan of nonexistent lun
During a manual scan, a user can send command to a nonexistent
lun, precisely at the point of max_lun. Normally it's possible
(but not required) that the firmware has the knowledge that it
is an invalid lun. In the particular case when max_lun is 256,
however, the nonexistent lun 256 will be confused with lun 0,
because the lun member in a request message is only u8, and 256
will become 0. So we need to fix the problem, at least, at the
driver level.

Subject: [PATCH 0399/1816] sony_pi: Remove the BKL from open and ioctl
The BKL is in this function because of the BKL pushdown (see commit
f8f2c79d594463427f7114cedb1555110d547d89)
It is not needed here because the mutex_lock sonypi_device.lock provides
the necessary locking.
sonypi_misc_ioctl can be converted to unlocked ioctls since it relies on
its own locking (the mutex sonypi_device.lock) and not the bkl
Document that llseek is not needed by explictly setting it to no_llseek

Subject: [PATCH 0403/1816] sysfs: Add lockdep annotations for the sysfs active
reference
Holding locks over device_del -> kobject_del -> sysfs_deactivate can
cause deadlocks if those same locks are grabbed in sysfs show or store
methods.
The I model s_active count + completion as a sleeping read/write lock.
I describe to lockdep sysfs_get_active as a read_trylock,
sysfs_put_active as a read_unlock, and sysfs_deactivate as a
write_lock and write_unlock pair. This seems to capture the essence
for purposes of finding deadlocks, and in my testing gives finds real
issues and ignores non-issues.
This brings us back to holding locks over kobject_del is a problem
that ideally we should find a way of addressing, but at least lockdep
can tell us about the problems instead of requiring developers to debug
rare strange system deadlocks, that happen when sysfs files are removed
while being written to.

was done after the last possible loop.
Then timeout==0 regardless of (val & OCP_READY_MASK) or
!(val & OCP_READY_MASK), leading to possible false timeout...
Simple correction could be decreasing timeout after checking
for !(val & OCP_READY_MASK), not before
(Manually converted from email to an actual patch by me. -- JWL)

Subject: [PATCH 0411/1816] ath5k: Fix eeprom checksum check for custom sized
eeproms
Commit 8bf3d79bc401ca417ccf9fc076d3295d1a71dbf5 enabled EEPROM
checksum checks to avoid bogus bug reports but failed to address
updating the code to consider devices with custom EEPROM sizes.
Devices with custom sized EEPROMs have the upper limit size stuffed
in the EEPROM. Use this as the upper limit instead of the static
default size. In case of a checksum error also provide back the
max size and whether or not this was the default size or a custom
one. If the EEPROM is busted we add a failsafe check to ensure
we don't loop forever or try to read bogus areas of hardware.
This closes bug 14874

Commit e0cd516 "PCI: derive nearby CPUs from device's instead of bus'
NUMA information" causes an null pointer dereference when reading from
the sysfs attributes local_cpu* on Intel machines with no ACPI NUMA
proximity info, since dev->numa_node gets set to -1 for all PCI devices,
which then gets passed to cpumask_of_node.
Add a check to prevent this.

Subject: [PATCH 0417/1816] bbc_envctrl: Clean up properly if kthread_run()
fails.
In bbc_envctrl_init() we have to unlink the fan and temp instances
from the lists because our caller is going to free up the 'bp' object
if we return an error.
We can't rely upon bbc_envctrl_cleanup() to do this work for us in
this case.

Subject: [PATCH 0419/1816] PCI/PM: Use per-device D3 delays
It turns out that some PCI devices require extra delays when changing
power state from D3 to D0 (and the other way around). Although this
is against the PCI specification, we can handle it quite easily by
allowing drivers to define arbitrary D3 delays for devices known to
require extra time for switching power states.
Introduce additional field d3_delay in struct pci_dev and use it to
store the value of the device's D0->D3 delay, in miliseconds. Make
the PCI PM core code use the per-device d3_delay unless
pci_pm_d3_delay is greater (in which case the latter is used).
[This also allows the driver to specify d3_delay shorter than the
10 ms required by the PCI standard if the device is known to be able
to handle that.]
Make the sky2 driver set d3_delay to 150 for devices handled by it.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14730 which is a
listed regression from 2.6.30.

This reverts commit ae1b22f6e46c03cede7cea234d0bf2253b4261cf.
As Linus said in 982d007a6ee: "There was something really messy about
cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it
carefully."
This breaks lguest for those configs, but we can fix that by emulating
if we have to.

Subject: [PATCH 0422/1816] reiserfs: Fix recursive lock on lchown
On chown, reiserfs will call reiserfs_setattr() to change the owner
of the given inode, but it may also recursively call
reiserfs_setattr() to propagate the owner change to the private xattr
files for this inode.
Hence, the reiserfs lock may be acquired twice which is not wanted
as reiserfs_setattr() calls journal_begin() that is going to try to
relax the lock in order to safely acquire the journal mutex.
Using reiserfs_write_lock_once() from reiserfs_setattr() solves
the problem.
This fixes the following warning, that precedes a lockdep report.

Subject: [PATCH 0423/1816] reiserfs: Relax the lock before truncating pages
While truncating a file, reiserfs_setattr() calls inode_setattr()
that will truncate the mapping for the given inode, but for that
it needs the pages locks.
In order to release these, the owners need the reiserfs lock to
complete their jobs. But they can't, as we don't release it before
calling inode_setattr().
We need to do that to fix the following softlockups:

Subject: [PATCH 0424/1816] reiserfs: Relax lock on xattr removing
When we remove an xattr, we call lookup_and_delete_xattr()
that takes some private xattr inodes mutexes. But we hold
the reiserfs lock at this time, which leads to dependency
inversions.
We can safely call lookup_and_delete_xattr() without the
reiserfs lock, where xattr inodes lookups only need the
xattr inodes mutexes.

Subject: [PATCH 0425/1816] exofs: fix pnfs_osd re-definitions in pre-pnfs
trees
Some on disk exofs constants and types are defined in the pnfs_osd_xdr.h
file. Since we needed these types before the pnfs-objects code was
accepted to mainline we duplicated the minimal needed definitions into
an exofs local header. The definitions where conditionally included
depending on !CONFIG_PNFS defined. So if PNFS was present in the tree
definitions are taken from there and if not they are defined locally.
That was all good but, the CONFIG_PNFS is planed to be included upstream
before the pnfs-objects is also included. (The first pnfs batch might be
pnfs-files only)
So condition exofs local definitions on the absence of pnfs_osd_xdr.h
inclusion (__PNFS_OSD_XDR_H__ not defined). User code must make sure
that in future pnfs_osd_xdr.h will be included before fs/exofs/pnfs.h,
which happens to be so in current code.
Once pnfs-objects hits mainline, exofs's local header will be removed.

Subject: [PATCH 0426/1816] exofs: simple_write_end does not mark_inode_dirty
exofs uses simple_write_end() for it's .write_end handler. But
it is not enough because simple_write_end() does not call
mark_inode_dirty() when it extends i_size. So even if we do
call mark_inode_dirty at beginning of write out, with a very
long IO and a saturated system we might get the .write_inode()
called while still extend-writing to file and miss out on the last
i_size updates.
So override .write_end, call simple_write_end(), and afterwords if
i_size was changed call mark_inode_dirty().
It stands to logic that since simple_write_end() was the one extending
i_size it should also call mark_inode_dirty(). But it looks like all
users of simple_write_end() are memory-bound pseudo filesystems, who
could careless about mark_inode_dirty(). I might submit a
warning-comment patch to simple_write_end() in future.

Use rt2x00dev->ops->extra_tx_headroom, not rt2x00dev->hw->extra_tx_headroom
in the tx code, as the later may include other headroom not to be used in

Subject: [PATCH 0433/1816] rt2x00: Fix LED configuration setting for rt2800.
rt2800_blink_set uses an illegal value to set the LED_CFG_G_LED_MODE
field of the LED_CFG register. This field is only 2 bits large, so
should be initialized with value that fits. Use default value from
the vendor driver.

Subject: [PATCH 0434/1816] mac80211: fix skb buffering issue
Since I removed the master netdev, we've been
keeping internal queues only, and even before
that we never told the networking stack above
the virtual interfaces about congestion. This
means that packets are queued in mac80211 and
the upper layers never know, possibly leading
to memory exhaustion and other problems.
This patch makes all interfaces multiqueue and
uses ndo_select_queue to put the packets into
queues per AC. Additionally, when the driver
stops a queue, we now stop all corresponding
queues for the virtual interfaces as well.
The injection case will use VO by default for
non-data frames, and BE for data frames, but
downgrade any data frames according to ACM. It
needs to be fleshed out in the future to allow
chosing the queue/AC in radiotap.

Subject: [PATCH 0435/1816] rt2x00: Properly request tx headroom for alignment
operations.
Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too
small" error message when a frame needs to be properly aligned before
transmitting it.
This is because the space needed to ensure proper alignment isn't
requested from mac80211.
Fix this by adding sufficient amount of alignment space to the amount
of headroom requested for TX frames.

Subject: [PATCH 0436/1816] x86: copy_from_user() should not return -EFAULT
Callers of copy_from_user() expect it to return the number of bytes
it could not copy. In no case it is supposed to return -EFAULT.
In case of a detected buffer overflow just return the requested
length. In addition one could think of a memset that would clear
the size of the target object.
[ hpa: code is not in .32 so not needed for -stable ]

Subject: [PATCH 0437/1816] iwlwifi: remove linux/utsrelease.h dependency
Commit 250cce26d5d03337aec4ff8405121f026adb4a89 uses UTS_RELEASE
as the the in-tree iwlwifi driver version. However the inclusion
of generated/utsrelease.h makes it a unpleasant behaviour to
recompile the driver everytime when utsrelease.h is updated. In
fact, the driver module is already built with the UTS_RELEASE
information via vermagic of modinfo. Mark the in-tree driver
with the version string "in-tree" to distinguish with those old
out-of-tree drivers.

Fix it by casting the pointers to unsigned long instead. This makes the
compiler happy again.

Subject: [PATCH 0440/1816] mac80211: fix ieee80211_change_mac() to use struct
sockaddr
Setting the mac address from user space was buggy. For example, when
executing this command:
ip link set wlan0 address 00:1f:df:88:cd:55
mac80211 used the address 01:00:00:1f:df:88 instead. It was shifted two
bytes.
The reason was that the addr (type of void *) provided to
ieee80211_change_mac() is actually of type struct sockaddr, not just the
mac address array. Also the call to eth_mac_addr() expects the address to
be struct sockaddr.

Subject: [PATCH 0447/1816] mwl8k: handle station database update for AP's sta
entry via ->sta_notify()
Inserting and removing a hardware station database entry for the AP
when we are in managed mode is currently done in ->bss_info_changed().
To prepare for adding AP mode support, implement the ->sta_notify()
driver method, and let that handle inserting and removing the hardware
station database entry for our AP instead.

Subject: [PATCH 0449/1816] mwl8k: move ->peer_id from mwl8k_vif to mwl8k_sta
For STA firmware, move the per-peer hardware station ID to the
driver-private part of struct ieee80211_sta, where it belongs.
(Since issuing a hardware station database maintenance command sleeps,
we can't hold a reference to the ieee80211_sta * across the command,
and since we won't know the station ID until after the command
completes, we need to re-lookup the sta when the command is done to
write the returned station ID back to its driver-private part.)

Subject: [PATCH 0450/1816] mwl8k: honor peer rate set
When calling SET_RATE, SET_AID, or when creating a station database
entry for our AP, pass in the AP's rate set instead of just blindly
enabling all legacy rates, so as to end up doing the right thing when
talking to 11b-only APs.

Subject: [PATCH 0451/1816] mwl8k: fix changed flags handling in
mwl8k_bss_info_changed()
Previously, mwl8k_bss_info_changed() would refuse to do anything if
the 'changed' argument indicated that the association status hadn't
changed. Fix this up so that it will allow changing things like the
preamble type, the slot time and the CTS-to-self protection method
without having to reassociate.

Subject: [PATCH 0457/1816] mac80211: fix ampdu_action tx_start ssn
The start_seq_num is taken from the station's tid_seq[tid].
This is fine, except tid_seq sequence counter is shifted
by 4 bits to accommodate for frame fragmentation.
Both (iwlagn & ath9k) were unaffected by this minor glitch,
because they don't read the *ssn for the AMPDU_TX_START action.

Subject: [PATCH 0459/1816] Revert "x86: Side-step lguest problem by only
building cmpxchg8b_emu for pre-Pentium"
This reverts commit ae1b22f6e46c03cede7cea234d0bf2253b4261cf.
As Linus said in 982d007a6ee: "There was something really messy about
cmpxchg8b and clone CPU's, so if you enable it on other CPUs later, do it
carefully."
This breaks lguest for those configs, but we can fix that by emulating
if we have to.

Subject: [PATCH 0464/1816] Input: serio - fix potential deadlock when
unbinding drivers
sysfs_remove_group() waits for sysfs attributes to be removed, therefore
we do not need to worry about driver-specific attributes being accessed
after driver has been detached from the device. In fact, attempts to take
serio->drv_mutex in attribute methods may lead to the following deadlock:
sysfs_read_file()
fill_read_buffer()
sysfs_get_active_two()
psmouse_attr_show_helper()
serio_pin_driver()
serio_disconnect_driver()
mutex_lock(&serio->drv_mutex);
<--------> mutex_lock(&serio_drv_mutex);
psmouse_disconnect()
sysfs_remove_group(... psmouse_attr_group);
....
sysfs_deactivate();
wait_for_completion();
Fix this by removing calls to serio_[un]pin_driver() and functions themselves
and using driver-private mutexes to serialize access to attribute's set()
methods that may change device state.

We need to first unregister input device and only then cancel event work
since events can arrive (and cause event work to get scheduled again)
until input_unregister_device() returns.

Subject: [PATCH 0466/1816] Input: evdev - be less aggressive about sending
SIGIO notifies
When using realtime signals, we'll enqueue one signal for every event.
This is unfortunate, because (for example) keyboard presses are three
events: key, msc scancode, and syn. They'll be enqueued fast enough in
kernel space that all three events will be ready to read by the time
userspace runs, so the first invocation of the signal handler will read
all three events, but then the second two invocations still have to run
to do no work.
Instead, only send the SIGIO notification on syn events. This is a
slight abuse of SIGIO semantics, in principle it ought to fire as soon
as any events are readable. But it matches evdev semantics, which is
more important since SIGIO is rather vaguely defined to begin with.

Subject: [PATCH 0469/1816] modules: Skip empty sections when exporting section
notes
Commit 35dead4 "modules: don't export section names of empty sections
via sysfs" changed the set of sections that have attributes, but did
not change the iteration over these attributes in add_notes_attrs().
This can lead to add_notes_attrs() creating attributes with the wrong
names or with null name pointers.
Introduce a sect_empty() function and use it in both add_sect_attrs()
and add_notes_attrs().

Subject: [PATCH 0472/1816] davinci: cp_intc: provide set_wake function
There is nothing special to be done for interrupts
which can wakeup the device from sleep on CP-INTC,
but not having a set_wake implemented prevents use
of common drivers which expect this function to be
implemented for all wakeup interrupt sources.
This patch fixes the issue encountered when using the
omap-rtc driver on DA850. On DA850 the RTC alarm
interrupt is used to wake up the SoC from deep sleep
mode. Without this patch, the disable_irq_wake throws
an unbalanced wake disable warning while resuming
because the previous enable call fails for lack of
set_wake implementation.

Subject: [PATCH 0473/1816] davinci: da8xx/omap-l1: mark RTC as a wakeup source
On da850, RTC alarm is a wakeup source from deep sleep.
Mark it as a wakeup source after the rtc platform device
is registered.
Without this patch, the rtc-omap driver suspends the RTC
during the suspend sequence and hence it cannot wakeup the
SoC.

Subject: [PATCH 0474/1816] davinci: enable ARCH_HAS_HOLES_MEMORYMODEL for
DaVinci
All DaVinci platforms include a DSP or co-processor for
audio/video acceleration.
While creating memory for the DSP/co-processor, system
integrator can end up creating a hole in the memory map
of the sort:
<kernel memory> <hole (memory for DSP)> <kernel memory>
This sort of configuration needs ARCH_HAS_HOLES_MEMORYMODEL
enabled. See further details see this discussion on ARM
linux mailing list:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg15262.html
The patch is boot tested on OMAP-L138, DM6446 and DM355 EVMs

From 76446cac68568fc7f5168a27deaf803ed22a4360 Mon Sep 17 00:00:00 2001
From: Jesse Barnes <jbarnes@virtuousgeek.org>
Date: Thu, 17 Dec 2009 22:05:42 -0500
Subject: [PATCH 0476/1816] drm/i915: execbuf2 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds a new execbuf ioctl, execbuf2, for use by clients that
want to control fence register allocation more finely. The buffer
passed in to the new ioctl includes a new relocation type to indicate
whether a given object needs a fence register assigned for the command
buffer in question.
Compatibility with the existing execbuf ioctl is implemented in terms
of the new code, preserving the assumption that fence registers are
required for pre-965 rendering commands.

Subject: [PATCH 0477/1816] drm/i915: Fix RC6 suspend/resume
We restored RC6 twice on resume, even with modesetting off. Instead,
only restore it once and skip RC6 initialization entirely in non-KMS mode.

Subject: [PATCH 0478/1816] drm/i915: remove render reclock support
This code generally fails to adjust the render clock, and when it does,
it conflicts with some other register settings and can cause problems.
So remove this code altogether. I'm reworking it now to do the right
thing, but the only bit it will share is the VBT check for whether
reclocking is supported, so I'm leaving that bit.
Reverts most of 652c393a3368af84359da37c45afc35a91144960 ("add dynamic
clock frequency control"), though for many the regressions showed up
in the later 181a5336d6cc836f05507410d66988c483ad0154 ("Fix render
reclock availability detection").

Partly this is because gcc isn't smart enough. But `ll_base' does get used
uninitialised in the DRM_DEBUG() call.

It is in fact slightly more insiduous that first appears since we are
attempting to not just free the object without the lock, but are trying
to do the whole bo manipulation without holding the lock.

Subject: [PATCH 0486/1816] drm/i915: Add DP dpll limit on ironlake and use
existing DPLL search function
For some clocks, the old Ironlake DPLL calculator wold give m/n/p
combinations that didn't match the spreadsheet of what HW validation
tests. Instead, use the G4X DPLL calculator, which does a better job
at it.
So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS
on ironlake. At the same time to consider the dpll setting for display port, we
add the display port DPLL limit on ironlake, which will directly use the
function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

This one reverts 9e3a6d155ed0a7636b926a798dd7221ea107b274.
As reported by http://bugzilla.kernel.org/show_bug.cgi?id=14485,
this dump will cause hang problem on some machine. If something
really needs this kind of full registers dump, that could be done
within intel-gpu-tools.

Subject: [PATCH 0488/1816] x86, irq: Check move_in_progress before freeing the
vector mapping
With the recent irq migration fixes (post 2.6.32), Gary Hade has noticed
"No IRQ handler for vector" messages during the 2.6.33-rc1 kernel boot on IBM
AMD platforms and root caused the issue to this commit:
> commit 23359a88e7eca3c4f402562b102f23014db3c2aa
> Author: Suresh Siddha <suresh.b.siddha@intel.com>
> Date: Mon Oct 26 14:24:33 2009 -0800
>
> x86: Remove move_cleanup_count from irq_cfg
As part of this patch, we have removed the move_cleanup_count check
in smp_irq_move_cleanup_interrupt(). With this change, we can run into a
situation where an irq cleanup interrupt on a cpu can cleanup the vector
mappings associated with multiple irqs, of which one of the irq's migration
might be still in progress. As such when that irq hits the old cpu, we get
the "No IRQ handler" messages.
Fix this by checking for the irq_cfg's move_in_progress and if the move
is still in progress delay the vector cleanup to another irq cleanup
interrupt request (which will happen when the irq starts arriving at the
new cpu destination).

Subject: [PATCH 0498/1816] sunrpc: fix peername failed on closed listener
There're some warnings of "nfsd: peername failed (err 107)!"
socket error -107 means Transport endpoint is not connected.
This warning message was outputed by svc_tcp_accept() [net/sunrpc/svcsock.c],
when kernel_getpeername returns -107. This means socket might be CLOSED.
And svc_tcp_accept was called by svc_recv() [net/sunrpc/svc_xprt.c]
if (test_bit(XPT_LISTENER, &xprt->xpt_flags)) {
<snip>
newxpt = xprt->xpt_ops->xpo_accept(xprt);
<snip>
So this might happen when xprt->xpt_flags has both XPT_LISTENER and XPT_CLOSE.
Let's take a look at commit b0401d72, this commit has moved the close
processing after do recvfrom method, but this commit also introduces this
warnings, if the xpt_flags has both XPT_LISTENER and XPT_CLOSED, we should
close it, not accpet then close.

Subject: [PATCH 0499/1816] [IA64] cpumask_of_node() should handle -1 as a node
pcibus_to_node can return -1 if we cannot determine which node a pci bus
is on. If passed -1, cpumask_of_node will negatively index the lookup array
and pull in random data:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus

# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist

Change cpumask_of_node to check for -1 and return cpu_all_mask in this
case:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
ffffffff,ffffffff,ffffffff,ffffffff

Subject: [PATCH 0503/1816] ring-buffer: Wrap a list.next reference with
rb_list_head()
This reference at the end of rb_get_reader_page() was causing off-by-one
writes to the prev pointer of the page after the reader page when that
page is the head page, and therefore the reader page has the RB_PAGE_HEAD
flag in its list.next pointer. This eventually results in a GPF in a
subsequent call to rb_set_head_page() (usually from rb_get_reader_page())
when that prev pointer is dereferenced. The dereferenced register would
characteristically have an address that appears shifted left by one byte
(eg, ffxxxxxxxxxxxxyy instead of ffffxxxxxxxxxxxx) due to being written at
an address one byte too high.

Subject: [PATCH 0504/1816] ring-buffer: Add rb_list_head() wrapper around new
reader page next field
If the very unlikely case happens where the writer moves the head by one
between where the head page is read and where the new reader page
is assigned _and_ the writer then writes and wraps the entire ring buffer
so that the head page is back to what was originally read as the head page,
the page to be swapped will have a corrupted next pointer.
Simple solution is to wrap the assignment of the next pointer with a
rb_list_head().

Subject: [PATCH 0505/1816] FDPIC: Respect PT_GNU_STACK exec protection
markings when creating NOMMU stack
The current code will load the stack size and protection markings, but
then only use the markings in the MMU code path. The NOMMU code path
always passes PROT_EXEC to the mmap() call. While this doesn't matter
to most people whilst the code is running, it will cause a pointless
icache flush when starting every FDPIC application. Typically this
icache flush will be of a region on the order of 128KB in size, or may
be the entire icache, depending on the facilities available on the CPU.
In the case where the arch default behaviour seems to be desired
(EXSTACK_DEFAULT), we probe VM_STACK_FLAGS for VM_EXEC to determine
whether we should be setting PROT_EXEC or not.
For arches that support an MPU (Memory Protection Unit - an MMU without
the virtual mapping capability), setting PROT_EXEC or not will make an
important difference.
It should be noted that this change also affects the executability of
the brk region, since ELF-FDPIC has that share with the stack. However,
this is probably irrelevant as NOMMU programs aren't likely to use the
brk region, preferring instead allocation via mmap().

Subject: [PATCH 0506/1816] NOMMU: Avoiding duplicate icache flushes of shared
maps
When working with FDPIC, there are many shared mappings of read-only
code regions between applications (the C library, applet packages like
busybox, etc.), but the current do_mmap_pgoff() function will issue an
icache flush whenever a VMA is added to an MM instead of only doing it
when the map is initially created.
The flush can instead be done when a region is first mmapped PROT_EXEC.
Note that we may not rely on the first mapping of a region being
executable - it's possible for it to be PROT_READ only, so we have to
remember whether we've flushed the region or not, and then flush the
entire region when a bit of it is made executable.
However, this also affects the brk area. That will no longer be
executable. We can mprotect() it to PROT_EXEC on MPU-mode kernels, but
for NOMMU mode kernels, when it increases the brk allocation, making
sys_brk() flush the extra from the icache should suffice. The brk area
probably isn't used by NOMMU programs since the brk area can only use up
the leavings from the stack allocation, where the stack allocation is
larger than requested.

Subject: [PATCH 0507/1816] NOMMU: Use copy_*_user_page() in
access_process_vm()
The MMU code uses the copy_*_user_page() variants in access_process_vm()
rather than copy_*_user() as the former includes an icache flush. This
is important when doing things like setting software breakpoints with
gdb. So switch the NOMMU code over to do the same.
This patch makes the reasonable assumption that copy_from_user_page()
won't fail - which is probably fine, as we've checked the VMA from which
we're copying is usable, and the copy is not allowed to cross VMAs. The
one case where it might go wrong is if the VMA is a device rather than
RAM, and that device returns an error which - in which case rubbish will
be returned rather than EIO.

Subject: [PATCH 0508/1816] ARM: S3C64XX: Fix possible clock look in EPLL and
MPLL clock chains
There is a possibility of a loop happening in the PLL output clock
chain on the S3C64XX series. clk_mpll's parent was set to be
clk_mout_mpll, but this is fed from clk_fout_epll (which is also
clk_mpll).
clk_mpll is meant to be the output from the MPLL, and clk_mout_mpll
is a seperate clock derived from the mux of clk_mpll and clk_fin_mpll
and thus should be considered a seperate clock.
Anything using clk_mpll directly really should not be relying on this
being the clock that is eventually routed to a peripheral, so remove the
loop and ensure that the clocks accurately represent the clock chain
in the device.
The clk_mpll is not being used outside of the s3c6400-clock.c code, so
this change should not break anything else.
Do the same for the EPLL.

Subject: [PATCH 0509/1816] drm: remove address mask param for drm_pci_alloc()
drm_pci_alloc() has input of address mask for setting pci dma
mask on the device, which should be properly setup by drm driver.
And leave it as a param for drm_pci_alloc() would cause confusion
or mistake would corrupt the correct dma mask setting, as seen on
intel hw which set wrong dma mask for hw status page. So remove
it from drm_pci_alloc() function.

Subject: [PATCH 0520/1816] sky2: Lock transmit queue while disabling device
netif_device_detach() does not take the tx_lock, so it's possible that
a call to sky2_xmit_frame is still in progress after
netif_device_detach() is complete.
Take netif_tx_lock() to make sure all transmits have stopped while
we're disabling the devices and that no other CPU is still
transmitting a frame after we've disabling the device.
Proposed fix for "sky2 panic under load" reported by Berck E. Nash.

Subject: [PATCH 0521/1816] qlge: Turn on RX header split based on platform.
Using 4-byte aligned headers is problematic for some architectures.
Since qlge uses 4-byte aligned rx buffers we split headers for these
architectures into a separate buffer and then recopy to align on 2-byte boundary.

Subject: [PATCH 0524/1816] ucc_geth: Fix the wrong the Rx/Tx FIFO size
current the Rx/Tx FIFO size settings cause problem
when four UEC ethernets work simultaneously.
eg: GETH1, UEM-J15, GETH2, UEC-J5 on 8569MDS board
$ ifconfig eth0 10.193.20.166
$ ifconfig eth1 10.193.20.167
$ ifconfig eth2 10.193.20.168
then
$ ifconfig eth3 10.193.20.169
The fourth ethernet will cause all of interface broken,
you cann't ping successfully any more.
The patch fix this issue for MPC8569 Rev1.0 and Rev2.0

SMSC Ethernet Transceivers (LAN88710, LAN8710, LAN8720, LAN8187,
LAN8700, LAN83C185) provide a mechanism to conserve power when
the device is not connected to an active link partner
(Energy Detect Mode).
So this patch enables the Energy Detect power-down mode
for these Transceivers.

Subject: [PATCH 0526/1816] ip: fix mc_loop checks for tunnels with multicast
outer addresses
When we have L3 tunnels with different inner/outer families
(i.e. IPV4/IPV6) which use a multicast address as the outer tunnel
destination address, multicast packets will be loopbacked back to the
sending socket even if IP*_MULTICAST_LOOP is set to disabled.
The mc_loop flag is present in the family specific part of the socket
(e.g. the IPv4 or IPv4 specific part). setsockopt sets the inner
family mc_loop flag. When the packet is pushed through the L3 tunnel
it will eventually be processed by the outer family which if different
will check the flag in a different part of the socket then it was set.

Don't send flow control settings to any port other than the modem port.
Older firmware ignored this request but did sent a reply. Newer firmware just
ignores it without reply and causes a 5 second timeout every time a port
(except for the modem port) is opened or if tiocm settings are changed.

This patch fixes up a problem with found with commit
1f3c8804acba841b5573b953f5560d2683d2db0d. The original change
overloaded null_or_orig, but doing that prevented any packet handlers
that were not tied to a specific device (i.e. ptype->dev == NULL) from
ever receiving any frames.
The null_or_orig variable cannot be overloaded, and must be kept as NULL
to prevent the frame from being ignored by packet handlers designed to
accept frames on any interface.

Subject: [PATCH 0545/1816] net: RFC3069, private VLAN proxy arp support
This is to be used together with switch technologies, like RFC3069,
that where the individual ports are not allowed to communicate with
each other, but they are allowed to talk to the upstream router. As
described in RFC 3069, it is possible to allow these hosts to
communicate through the upstream router by proxy_arp'ing.
This patch basically allow proxy arp replies back to the same
interface (from which the ARP request/solicitation was received).
Tunable per device via proc "proxy_arp_pvlan":
/proc/sys/net/ipv4/conf/*/proxy_arp_pvlan
This switch technology is known by different vendor names:
- In RFC 3069 it is called VLAN Aggregation.
- Cisco and Allied Telesyn call it Private VLAN.
- Hewlett-Packard call it Source-Port filtering or port-isolation.
- Ericsson call it MAC-Forced Forwarding (RFC Draft).

Subject: [PATCH 0546/1816] net: Make it easier to parse /proc/net/dev
contents.
The contents of /proc/net/dev is annoying to parse, because
it changes whether there is a space after the "ethX:" or not.
It depends upon the size of the "Receive bytes" counter,
if the number is below 7 digits, then there is whitespaces
else if the number is 8 digits or above there is no space
between the ":" and the number.
This patch changes the output to assure there is always a space
between the ":" and the number. Given that all existing userspace
application already need to handle the whitespaces, I see
no breakage of existing tools.

Subject: [PATCH 0550/1816] mv643xx_eth: don't include cache padding in rx desc
buffer size
If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth
allocates a couple of extra bytes at the start of each receive buffer
to make the data payload end up on a cache line boundary.
These extra bytes are skb_reserve()'d before DMA mapping, so they
should not be included in the DMA map byte count (as the mapping is
done starting at skb->data), nor should they be included in the
receive descriptor buffer size field, or the hardware can end up
DMAing beyond the end of the buffer, which can happen if someone
sends us a larger-than-MTU sized packet.
This problem was introduced in commit 7fd96ce47ff ("mv643xx_eth:
rework receive skb cache alignment", May 6 2009), but hasn't appeared
to be problematic so far, probably as the main users of mv643xx_eth
all have NET_SKB_PAD == L1_CACHE_BYTES.

Subject: [PATCH 0554/1816] drivers/firmware/iscsi_ibft.c: use %pM to show MAC
address
Use the %pM kernel extension to display the MAC address.
Also, remove the 'mac' variable and use nic->mac directly.

Subject: [PATCH 0564/1816] drivers/infiniband/hw/cxgb3/iwch_cm.c: use %pM to
show MAC address
Use the %pM kernel extension to display the MAC address.
The only difference in the output is that the MAC address is
shown in the usual colon-separated hex notation.

Subject: [PATCH 0566/1816] Input: psmouse - fix Synaptics detection when
protocol is disabled
For configurations where Synaptics hardware is present but the Synaptics
extensions support is not compiled in, the mouse is reprobed and a new
device is allocated on every suspend/resume.
During probe, psmouse_switch_protocol() calls psmouse_extensions() with
set_properties=1. This calls the dummy synaptics_init() which returns an
error code, instructing us not to use the synaptics extensions.
During resume, psmouse_reconnect() calls psmouse_extensions() with
set_properties=0, in which case call to synaptics_init() is bypassed and
PSMOUSE_SYNAPTICS is returned. Since the result is different from previous
attempt psmouse_reconnect() fails and full re-probe happens.
Fix this by tweaking the set_properties=0 codepath in psmouse_extensions()
to be more careful about offering PSMOUSE_SYNAPTICS extensions.

Subject: [PATCH 0567/1816] reiserfs: Don't call reiserfs_get_acl() with the
reiserfs lock
reiserfs_get_acl is usually not called under the reiserfs lock,
as it doesn't need it. But it happens when it is called by
reiserfs_acl_chmod(), which creates a dependency inversion against
the private xattr inodes mutexes for the given inode.
We need to call it without the reiserfs lock, especially since
it's unnecessary.

Subject: [PATCH 0574/1816] blackfin,kgdb,probe_kernel: Cleanup
probe_kernel_read/write
Blackfin needs it own arch specific probe_kernel_read() and
probe_kernel_write().
This was moved out of the kgdb code and into the
arch/blackfin/maccess.c, because it is a generic kernel api.
The arch specific kgdb.c for blackfin was cleaned of all functions
which exist in the kgdb core that do the same thing after resolving
the probe_kernel_read() and probe_kernel_write(). This also
eliminated the need for most of the #include's.

In blackfin, kgdb is running in delayed exception IRQ5 other than in
exception IRQ3 directly. Register reti other than retx in pt_regs is
the kgdb return address. So, don't put PC in gdb_regs into retx.

Subject: [PATCH 0579/1816] drm/i915: Use find_pll function to calculate DPLL
setting for LVDS downclock
For any given clock we can use the find_pll to get the corresponding DPLL
setting. It is unnecessary to use the find_reduce_pll callback function
to calculate the DPLL parameter for LVDS downclock in order to get the same
divider factor(P) for the normal and downclock.
In theory when the LVDS downclock is supported by LVDS panel, we should get the
same DPLL divider factor(P) for the normal clock and reduced downclock.
If we get the diferent divider factor(P) for normal clock and reduced downclock,
it means that the found downclock is incorrect and should be discarded.
So we should use find_pll callback to calculate the DPLL parameter for the
LVDS reduced downclock as for the normal clock. Then we can do the cleanup
about find_reduced_pll.

Subject: [PATCH 0581/1816] [IA64] __per_cpu_idtrs[] is a memory hog
__per_cpu_idtrs is statically allocated ... on CONFIG_NR_CPUS=4096
systems it hogs 16MB of memory. This is way too much for a quite
probably unused facility (only KVM uses dynamic TR registers).
Change to an array of pointers, and allocate entries as needed on
a per cpu basis. Change the name too as the __per_cpu_ prefix is
confusing (this isn't a classic <linux/percpu.h> type object).

Subject: [PATCH 0586/1816] stmmac: convert unicast addr list to list_head
This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr.
Note: this patch also removes a debug printk used for displaying the
mac addresses. Indeed, it's is possible to dump the registers with
ethtool.

This patch fixes the fix_mac_speed invocation
that cannot be done if it is a NULL pointer.

Subject: [PATCH 0591/1816] stmmac: reorganise class operations.
This patch reorganises the internal stmmac ops structure.
The stmmac_ops has been splitted into other three structures named:
stmmac_ops
stmmac_dma_ops
stmmac_desc_ops
This makes the code more clear and also helps the next work to
make the driver more generic.

From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 6 Jan 2010 23:07:18 +0000
Subject: [PATCH 0592/1816] stmmac: move the dma out from the main
This patch moves the dma related functions (interrupt, start, stop etc.)
out from the main driver code. This will help to support new DMA
engines.

From 7e848ae113ca7442ba6b44168fa2238224f37e8a Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 6 Jan 2010 23:07:19 +0000
Subject: [PATCH 0593/1816] stmmac: rename mac100 as dwmac100 and fix spare
coding style
This patch renames the mac100.[ch] as dwmac100.[ch]; this
looks more specific and appropriate for these chip series.
The patch also fixes some spare coding style issues.

From 21d437cc66dcfd0119a4905214fbbe19f3e276dc Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 6 Jan 2010 23:07:20 +0000
Subject: [PATCH 0594/1816] stmmac: rename the gmac as dwmac1000 and split core
and dma parts
Use dwmac1000 naming instead of gmac.
The patch also splits the gmac.c file in two new ones:
dwmac1000_core.c and dwmac1000_dma.c.
This could actually help on some architectures where different
DMA engines are used.

Subject: [PATCH 0599/1816] dmfe/tulip: Let dmfe handle DM910x except for SPARC
on-board chips
The Davicom DM9100 and DM9102 chips are used on the motherboards of
some SPARC systems (supported by the tulip driver) and also in PCI
expansion cards (supported by the dmfe driver). There is no
difference in the PCI device ids for the two different configurations,
so these drivers both claim the device ids. However, it is possible
to distinguish the two configurations by the presence of Open Firmware
properties for them, so we do that.

Subject: [PATCH 0600/1816] TI DaVinci EMAC: Handle emac module clock
correctly.
In the driver probe function the emac module clock needs to
be enabled before calling register_netdev(). As soon as the
device is registered the driver get_stats function can be invoked
by the core - the module clock must be switched on to be able to
read from stats registers. Also explicitly call matching clk_disable
for failure conditions in probe function.

Subject: [PATCH 0605/1816] drm: Add eDP connector type
Add a new connector type for eDP (embedded displayport)
eDP is more or less the same as DP but there are some
cases when you might want to handle it separately.

Subject: [PATCH 0608/1816] drm/radeon/kms: detect sideport memory on IGP chips
This detects if the sideport memory is enabled and
if it is VRAM is evicted on suspend/resume.
This should fix s/r issues on some IGPs.

Subject: [PATCH 0609/1816] drm/radeon/kms: Workaround RV410/R420 CP errata
(V3)
Long story short, this fixes sporadic hardlocks with my rv410 during
times of intense 2D acceleration (Flash on Fx3).
V2: Fix indentation and move errata_fini to suspend function so we
don't leak scratch register over suspend/resume cycle.
V3: Move scratch_reg to asic specific structure (aim is to slowly
move stuff to asic specific structure and avoid poluting
radeon_device struct with asic specific variables)

Subject: [PATCH 0610/1816] drm/radeon/kms: Schedule host path read cache flush
through the ring V2
R300 family will hard lockup if host path read cache flush is
done through MMIO to HOST_PATH_CNTL. But scheduling same flush
through ring seems harmless. This patch remove the hdp_flush
callback and add a flush after each fence emission which means
a flush after each IB schedule. Thus we should have same behavior
without the hard lockup.
Tested on R100,R200,R300,R400,R500,R600,R700 family.
V2: Adjust fence counts in r600_blit_prepare_copy()

setsockopt(s, SOL_SOCKET, SO_TIMESTAMP, 1); -> netstamp_needed = 1
bind(s, ...);
listen(s, ...);
s2 = accept(s, ...); -> netstamp_needed = 1
close(s2); -> netstamp_needed = 0
close(s); -> netstamp_needed = -1

The problem is that in the original code sound_nblocks could go up to 1024
which would be an array overflow.
This was found with a static checker and has been compile tested only.

Adaptive IFS which involves writing to the Adaptive IFS Throttle register
was being done for all devices supported by the driver even though it is
not supported (i.e. the register doesn't even exist) on some devices. The
feature is supported on 8257x/82583 and ICH/PCH based devices, but not
on ESB2.

Subject: [PATCH 0628/1816] e1000e: fix and commonize code for setting the
receive address registers
Fix e1000e_rar_set() to flush consecutive register writes to avoid write
combining which some parts cannot handle. Update e1000e_init_rx_addrs()
to call the fixed e1000e_rar_set() instead of duplicating code.
Also change e1000e_rar_set() to _not_ set the Address Valid bit if the MAC
address is all zeros.

Subject: [PATCH 0629/1816] bnx2: Flush the register writes which setup the
MSI-X table
The MSI-X table size needs to be properly set before pci_enable_msix()
is called. But on certain machines, the writes are delayed and the
MSI-X table size is incorrectly read. By reading the
BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now
ensure that the MSI-X table is set correctly before MSI-X
is enable on the device.

Subject: [PATCH 0630/1816] ep93xx_eth.c general cleanup
General cleanup of the ep93xx_eth driver.
1) Use pr_fmt() to prefix the module name and __func__ to the error
messages.
2) <linux/io.h> instead of <asm/io.h>
3) <mach/hardware.h> instead of <mach/ep93xx-regs.h> and <mach/platform.h>
4) Move the ep93xx_mdio_read (and ep93xx_mdio_write) function to eliminate
the function prototype.
5) Change all the printk(<level> messages to pr_<level> and remove the
__func__ argument.
6) Use platform_get_{resource/irq} to get the platform resources and add
an error check.
7) Use resource_size() for request_mem_region() and ioremap().
8) Use %pM to print the MAC address at the end of the probe.
9) Use dev->dev_addr not data->dev_addr for the MAC argument because a
random address could be used if the platform does not supply one.
The message at the end of the probe is left as a printk since it displays
cleaner without the function name that would be displayed with pr_info().

start_xmit function
The start_xmit function of the MSCAN Driver did return improperly if
the CAN dlc check failed (skb not freed and invalid return code). This
patch adds a proper check of the frame lenght and data size and returns
now correctly. The invalid skb packets are dropped silently as suggested
by David Miller in the thread "[RFC] ndo_validate_skb: Let the netdev
check a valid skb content" on the netdev mailing list.
Furthermore, a typo has been fixed.

Subject: [PATCH 0633/1816] can: mscan-mpc5xxx: add support for the MPC512x
processor
The main differences compared to the MSCAN on the MPC5200 are:
- More flexibility in choosing the CAN source clock and frequency:
Three different clock sources can be selected: "ip", "ref" or "sys".
For the latter two, a clock divider can be defined as well. If the
clock source is not specified by the device tree, we first try to
find an optimal CAN source clock based on the system clock. If that
is not possible, the reference clock will be used.
- The behavior of bus-off recovery is configurable:
To comply with the usual handling of Socket-CAN bus-off recovery,
"recovery on request" is selected (instead of automatic recovery).
Note that only MPC5121 Rev. 2 and later is supported.

Subject: [PATCH 0634/1816] powerpc/mpc5xxx: add OF platform binding doc for
FSL MSCAN devices
This patch adds documentation for the MSCAN OF device bindings for
the MPC512x and moves the one for the MPC5200 to the new common file
"Documentation/powerpc/dts-bindings/fsl/can.txt".

+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source shall be used for the controller:
+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+ are: "ip" for ip bus clock
+ "ref" for reference clock (XTAL)
+ "ref" is default in case this property is not
+ present.
+
+fsl,mpc5121-mscan nodes
+-----------------------
+In addition to the required compatible-, reg- and interrupt-properties, you can
+also specify which clock source and divider shall be used for the controller:
+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+ are: "ip" for ip bus clock
+ "ref" for reference clock
+ "sys" for system clock
+ If this property is not present, an optimal CAN
+ clock source and frequency based on the system
+ clock will be selected. If this is not possible,
+ the reference clock will be used.
+
+- fsl,mscan-clock-divider: for the reference and system clock, an additional
+ clock divider can be specified. By default, a
+ value of 1 is used.
+
+Note that the MPC5121 Rev. 1 processor is not supported.
+
+Examples:
+ can@1300 {
+ compatible = "fsl,mpc5121-mscan";
+ interrupts = <12 0x8>;
+ interrupt-parent = <&ipic>;
+ reg = <0x1300 0x80>;

Subject: [PATCH 0640/1816] GFS2: Ensure uptodate inode size when using
O_APPEND
The VFS reads the inode size during generic_file_aio_write() but
with no locking around it. In order to get the expected result
from O_APPEND opens, this patch updated the inode size before
calling generic_file_aio_write()
There is of course still a race here, in that there is nothing to
prevent another node coming in and extending the file in the
mean time. On the other hand, when used with file locking this
will ensure that the expected results are obtained.

Subject: [PATCH 0641/1816] GFS2: Fix locking bug in rename
The rename code was taking a resource group lock in cases where
it wasn't actually needed, this caused problems if the rename
was resulting in an inode being unlinked. The patch ensures that
we only take the rgrp lock early if it is really needed.

Subject: [PATCH 0649/1816] omap: gpio: Simultaneously requested rising and
falling edge
Some chips, namely any OMAP1 chips using METHOD_MPUIO,
OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO
interrupts in both rising and falling edge directions -- they can
only respond to one direction or the other, depending on how the
ICR is configured.
Additionally, current code forces rising edge detection if both
flags are specified:
if (trigger & IRQ_TYPE_EDGE_RISING)
l |= 1 << gpio;
else if (trigger & IRQ_TYPE_EDGE_FALLING)
l &= ~(1 << gpio);
else
goto bad;
This change implements a toggle function that will modify the ICR
to flip the direction of interrupt for IRQs that are requested with
both rising and falling flags. The toggle function is not called
for chips and GPIOs it does not apply to through the use of a flip_mask
that's added on a per-bank basis. The mask is only set for those
GPIOs where a toggle is necessary. Edge detection starts out the
same as above with FALLING mode first.
The toggle happens on EACH interrupt; without it, we have the
following sequence of actions on GPIO transition:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt
0x1 1 -> 0 (falling) No interrupt
(set ICR to 0x0 manually)
0x0 0 -> 1 (rising) No interrupt
0x0 1 -> 0 (falling) Interrupt
That is, with the ICR set to 1 for a gpio, only rising edge interrupts
are caught, and with it set to 0, only falling edge interrupts are
caught. If we add in the toggle, we get this:
ICR GPIO Result
0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0)
0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1)
0x1 0 -> 1 ...
so, both rising and falling are caught, per the request for both
(IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

Subject: [PATCH 0653/1816] omap1: Fix compile for omap1_bl.c
Commit 9905a43b made struct backlight_ops const. Omap was
setting check_fb dynamically, which caused the following
compile error:
drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe':
drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops'
Turns out pdata->check_fb is not being used, so just remove
it to fix the compile.

Commit f62349ee9788b1d94c55eb6c291d74a1f69bdd9e makes it possible to
have some other than first uart port as ttyS0, which breaks the workaround
serial_in_override() function which will try to address the first uart
port (for ttyS0) and not the one that was initialized.

Subject: [PATCH 0655/1816] omap2/3: ZOOM: Correcting key mapping for few keys
Keys: 'right arrow', 'up arrow' and 'select' were mapped
wrongly. This patch corrects them.
This patch also adds one missing key present in the board,
currently I added it as 'unknown' key, as I am not able to
find proper description for this key.
One key entry (r: 7, c: 5) is present in the keymap, which
is really not present in the board, removing it.

Commit 'mac80211: fix skb buffering issue' added an ->ndo_select_queue()
for monitor interfaces which can end up dereferencing ieee802_1d_to_ac[]
beyond the end of the array for injected data packets (as skb->priority
isn't guaranteed to be zero or within [0:7]), which then triggers the
WARN_ON in net/core/dev.c:dev_cap_txqueue(). Fix this by always setting
the priority to zero on injected data frames.

Various missing sanity checks caused rejected action frames to be

connectivity. This patch ensures that only spectrum management action

Subject: [PATCH 0665/1816] iwlwifi: fix iwl_queue_used bug when read_ptr ==
write_ptr
When txq read_ptr equals to write_ptr, iwl_queue_used should
always return false. Because there is no used TFD in this case.
This is a complementary fix to the fix already included in commit "iwl3945:
fix panic in iwl3945 driver". Both fixes are needed to address the panic
below.
This problem was discussed on linux-wireless in
http://thread.gmane.org/gmane.linux.kernel.wireless.general/43568

Subject: [PATCH 0666/1816] iwlwifi: disable tx on beacon update notification
On beacon change update notification from mac we are not disabling
the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when
station leaves IBSS. Driver should indicate uCode to not to send
anything on receiving this notification.
Functionality to indicate uCode is duplicated across
two notifications so created a common function called iwl_set_no_assoc.
Fix the issue at
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2133.

Subject: [PATCH 0668/1816] ARM: OMAP3: PM: Fix the Invalid CM_CLKSTCTRL reg
access.
In OMAP2/3 some of the clock-domains which did not have control
facility were being falsely written to and read using the CM_CLKSTCTRL
register though it did not exist for them. One check is added to remove
this flaw.

Subject: [PATCH 0669/1816] OMAP2xxx IO mapping: mark DSP mappings as being
2420-only
Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430,
we only map the IVA on OMAP2420. The memory mapping is not shared between
OMAP2420 and OMAP2430, so it is inappropriate to label those macros as
'24XX'; this patch changes them to '2420'.

address out of vmalloc space
Commit 10db25fea4c11661070b97832b8cc3d2af495092 causes the following
kernel messages during N800 boot (and presumably all other 2420
boards):
[ 0.000000] BUG: mapping for 0x58000000 at 0xe0000000 overlaps vmalloc space
[ 0.000000] BUG: mapping for 0x59000000 at 0xe1000000 overlaps vmalloc space
[ 0.000000] BUG: mapping for 0x5a000000 at 0xe2000000 overlaps vmalloc space
Fix by remapping the IVA memory areas somewhere outside vmalloc space.

The only symbols that should be exported are symbols that are to be
called from loadable kernel modules, e.g., device drivers. In the
context of plat-omap/clock.c, these should only be the Linux clock
interface symbols as defined by include/linux/clk.h. Core code
doesn't need these symbols to be exported. Also, clean up an old

Subject: [PATCH 0675/1816] OMAP1 clock: Add missing clocks for OMAP 7xx
This change adds in some missing clocks that were needed as a result
of 526505... (OMAP1 clock: convert mach-omap1/clock.h to
mach-omap1/clock_data.c). Prior to this, it was just assumed that
these clocks existed for all devices, and it was used directly instead
of calling it out with a clock_get call or similar. So, not having
the CK_7XX meant these clocks weren't being used anymore for omap 7xx
devices, which broke things badly.

Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da added an __initdata
decoration to the structure containing the clk_enable and clk_disable
functions. Once init data was freed, these pointers went to null, and
the next enable or disable call caused the kernel to crash. This
change removes this decoration.

Subject: [PATCH 0677/1816] OMAP2xxx clock: clk2xxx.c doesn't compile if
CPUFREQ is enabled
if we enable CPUFREQ we can't build omap2 for two reasons,
one of them is fixed by the patch below.
It's failing because the __must_be_array() check in
ARRAY_SIZE() is failing and printing the following message:
arch/arm/mach-omap2/clock2xxx.c:453: error: negative width in bit-field '<anonymous>'

Subject: [PATCH 0679/1816] OMAP clock/CPUFreq: add clk_exit_cpufreq_table()
A subsequent patch adds code on OMAP2xxx to dynamically allocate the
CPUFreq frequency table in clk_init_cpufreq_table(), so for it to
avoid a leak, it will need a corresponding function to free the
memory. This patch adds clk_exit_cpufreq_table() with generic
code to call a chip-specific variant inside the clockfw_lock spinlock via
struct clk_functions.

Subject: [PATCH 0680/1816] OMAP2 clock: dynamically allocate CPUFreq frequency
table
Dynamically allocate the CPUFreq frequency table on OMAP2xxx chips.
This fixes some compilation problems, since the kernel may not know
what chip it is running on until boot-time. This also reduces the size
of the CPUFreq frequency table.
Problem originally reported by Felipe Balbi <felipe.balbi@nokia.com>.
Thanks also for comments on the patch from Felipe and Kevin.

Subject: [PATCH 0681/1816] DRM / i915: Fix resume regression on MSI Wind U100
w/o KMS
Commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement
new pm ops for i915), among other things, removed the .suspend and
.resume pointers from the struct drm_driver object in i915_drv.c,
which broke resume without KMS on my MSI Wind U100.
Fix this by reverting that part of commit cbda12d77ea59.
[ The DRM layer will not use the class-specific suspend/resume functions
if the driver is marked MODESET-aware, and conversely it will not
register the PCI device if the drievr isn't so marked, so you always
end up with _either_ the drm-class suspend/resume _or_ the PCI layer
PM functionality, never both. - Linus ]

Subject: [PATCH 0682/1816] ARM: 5870/1: arch/arm: Fix build failure for
defconfigs without CONFIG_ISA_DMA_API set
A lot of ARM-defconfigs (those without CONFIG_ISA_DMA_API set) fail to
build [1][2][3] due to the changes of the patch
[PATCH] PCI: Clean up build for CONFIG_PCI_QUIRKS unset
by Rafael J. Wysocki (Sat, 2 Jan 2010 22:57:24 +0100) [4]
as the referenced variable 'isa_dma_bridge_buggy' in asm/dma.h is
enclosed by the CONFIG_ISA_DMA_API conditional all configs without this
setting fail to build.
I'm not sure wether moving the condition is the right way to solve the
issue, but atleast it fixes the issue :)

Subject: [PATCH 0686/1816] ARM: 5872/1: ARM: include needed linux/cpu.h in
asm/cpu.h
The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to
meet its dependency. Otherwise when using "struct cpuinfo_arm" and
including just 'asm/cpu.h' throws below error -
arch/arm/include/asm/cpu.h:16: error: field 'cpu' has incomplete type
To fix this otherway, one can also include both linux/cpu.h and
asm/cpu.h but it shoudn't be that way. So this patch fixes this by
including the linux/cpu.h in asm/cpu.h, so that including alone
asm/cpu.h is enough.

Subject: [PATCH 0689/1816] xfs: use DECLARE_EVENT_CLASS
Using DECLARE_EVENT_CLASS allows us to to use trace event code
instead of duplicating it in the binary. This was not available
before 2.6.33 so it had to be done as a separate step once the
prerequisite was merged.
This only requires changes to xfs_trace.h and the results are
rather impressive:

From d6d59bada372bcf8bd36c3bbc71c485c29dd2a4b Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@infradead.org>
Date: Wed, 23 Dec 2009 16:09:13 +0000
Subject: [PATCH 0690/1816] xfs: fix timestamp handling in xfs_setattr
We currently have some rather odd code in xfs_setattr for
updating the a/c/mtime timestamps:
- first we do a non-transaction update if all three are updated
together
- second we implicitly update the ctime for various changes
instead of relying on the ATTR_CTIME flag
- third we set the timestamps to the current time instead of the
arguments in the iattr structure in many cases.
This patch makes sure we update it in a consistent way:
- always transactional
- ctime is only updated if ATTR_CTIME is set or we do a size
update, which is a special case
- always to the times passed in from the caller instead of the
current time
The only non-size caller of xfs_setattr that doesn't come from
the VFS is updated to set ATTR_CTIME and pass in a valid ctime
value.

Subject: [PATCH 0691/1816] xfs: Don't flush stale inodes
Because inodes remain in cache much longer than inode buffers do
under memory pressure, we can get the situation where we have
stale, dirty inodes being reclaimed but the backing storage has
been freed. Hence we should never, ever flush XFS_ISTALE inodes
to disk as there is no guarantee that the backing buffer is in
cache and still marked stale when the flush occurs.

Subject: [PATCH 0692/1816] xfs: Ensure we force all busy extents in range to
disk
When we search for and find a busy extent during allocation we
force the log out to ensure the extent free transaction is on
disk before the allocation transaction. The current implementation
has a subtle bug in it--it does not handle multiple overlapping
ranges.
That is, if we free lots of little extents into a single
contiguous extent, then allocate the contiguous extent, the busy
search code stops searching at the first extent it finds that
overlaps the allocated range. It then uses the commit LSN of the
transaction to force the log out to.
Unfortunately, the other busy ranges might have more recent
commit LSNs than the first busy extent that is found, and this
results in xfs_alloc_search_busy() returning before all the
extent free transactions are on disk for the range being
allocated. This can lead to potential metadata corruption or
stale data exposure after a crash because log replay won't replay
all the extent free transactions that cover the allocation range.

(Dropped the "found" argument from the xfs_alloc_busysearch trace
event.)

Subject: [PATCH 0695/1816] hwmon: (asus_atk0110) Add debugfs interface
Expose the raw GGRP/GITM interface via debugfs. The hwmon interface is
reverse engineered and the driver tends to break on newer boards...
Using this interface it's possible to poke directly at the ACPI methods
without the need to recompile, reducing the guesswork and the round trips
needed to support a new revision of the interface.

processors
The latest version of the Revision Guide for AMD Family 10h Processors
lists two more processor revisions which may be affected by erratum 319.
Change the blacklisting code to correctly detect those processors, by
implementing AMD's recommended algorithm.

This driver permits reading of the internal temperature sensor of AMD
Family 10h and 11h processors.

+the sensor may return inconsistent values (erratum 319). The driver
+will refuse to load on these revisions unless you specify the "force=1"

+
+Due to technical reasons, the driver can detect only the mainboard's

+are using an AM3 processor on an AM2+ mainboard, you can safely use the
+"force=1" parameter.
There is one temperature measurement value, available as temp1_input in
sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.

CPUs
The max junction temperature of Atom N450/D410/D510 CPUs is 100 degrees
Celsius. Since these CPUs are always coupled with Intel NM10 chipset in
one package, the best way to verify whether an Atom CPU is N450/D410/D510
is to check the host bridge device.

From cbf698dbba25741ee1b2e734a6dd4f3070a1706f Mon Sep 17 00:00:00 2001
From: Greg Rose <gregory.v.rose@intel.com>
Date: Sat, 9 Jan 2010 02:23:50 +0000
Subject: [PATCH 0703/1816] ixgbevf: Mailbox communication
The 82599 virtual function device and the master 82599 physical function
device implement a mailbox utility for communication between the devices
using some SRAM scratch memory and a doorbell/answering mechanism enabled
via interrupt and/or polling. This C module and accompanying header
file implement the base functions for use of this feature.

+Linux* Base Driver for Intel(R) Network Connection
+==================================================
+
+November 24, 2009
+
+Contents
+========

+- In This Release
+- Identifying Your Adapter
+- Known Issues/Troubleshooting
+- Support
+
+In This Release
+===============
+
+This file describes the ixgbevf Linux* Base Driver for Intel Network
+Connection.
+
+The ixgbevf driver supports 82599-based virtual function devices that can only
+be activated on kernels with CONFIG_PCI_IOV enabled.
+
+The ixgbevf driver supports virtual functions generated by the ixgbe driver
+with a max_vfs value of 1 or greater.
+
+The guest OS loading the ixgbevf driver must support MSI-X interrupts.
+
+VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs.
+
+Identifying Your Adapter
+========================
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+ http://support.intel.com/support/network/sb/CS-008441.htm
+
+Known Issues/Troubleshooting
+============================
+
+ Unloading Physical Function (PF) Driver Causes System Reboots When VM is
+ Running and VF is Loaded on the VM
+ ------------------------------------------------------------------------
+ Do not unload the PF driver (ixgbe) while VFs are assigned to guests.
+
+Support
+=======
+
+For general information, go to the Intel support website at:
+
+ http://support.intel.com
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+ http://sourceforge.net/projects/e1000
+
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sf.net

From 10ca132c41ecc1b55bc22667493ab75c4f6eec0d Mon Sep 17 00:00:00 2001
From: Greg Rose <gregory.v.rose@intel.com>
Date: Sat, 9 Jan 2010 02:25:10 +0000
Subject: [PATCH 0707/1816] ixgbe: Mailbox header and code module
The 82599 virtual function device and the master 82599 physical function
device implement a mailbox utility for communication between the devices
using some SRAM scratch memory and a doorbell/answering mechanism enabled
via interrupt and/or polling. This C module and accompanying header
file implement the base functions for use of this feature.

Subject: [PATCH 0712/1816] ixgbe: Add SR-IOV features to main module
Adds SR-IOV features supported by the 82599 controller to the main driver
module. If the CONFIG_PCI_IOV kernel option is selected then the SR-IOV
features are enabled. Use the max_vfs module option to allocate up to 63
virtual functions per physical port.

From 89347bb8ef2d0af1ae8d847b7df91e9f04eccf2a Mon Sep 17 00:00:00 2001
From: David John <davidjon@xenontk.org>

Subject: [PATCH 0716/1816] drm: Keep disabled outputs disabled after suspend /
resume
With the current DRM code, an output that has been powered off
from userspace will automatically power back on when resuming
from suspend. This patch fixes this behaviour.
Tested only with the Intel i915 driver on an Intel GM45 Express
chipset.

Subject: [PATCH 0717/1816] drm/kms/fb: check for depth changes from userspace
for resizing.
If userspace (plymouth in this case) asks for a deeper depth,
refuse it as well due to lack of resizing.
This fixes an issue since < 32MB cards went to 8bpp and plymouth
crashes on startup.

Subject: [PATCH 0722/1816] drm/i2c/ch7006: Drop build time dependency to
nouveau.
This partially reverts e4b41066, as this driver is intended to be
useful with any KMS driver for suitable hardware. The missing build
dependency that commit workarounded was DRM_KMS_HELPER.

Date: Sat, 26 Dec 2009 02:42:45 +0100
Subject: [PATCH 0733/1816] drm/nouveau: Allocate a per-channel instance of
NV_SW.
It will be useful for various synchronization purposes, mostly stolen
from "[PATCH] drm/nv50: synchronize user channel after buffer object
move on kernel channel" by Maarten Maathuis.

Subject: [PATCH 0734/1816] drm/nouveau: Use the software object for fencing.
This should avoid a race condition on nv0x, if we're doing it with
actual PGRAPH objects and a there's a fence within the FIFO DMA fetch
area when a context switch kicks in.
In that case we get an ILLEGAL_MTHD interrupt as expected, but the
values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're
almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive
channel, with a wrong offset/data pair).

Subject: [PATCH 0736/1816] drm/nouveau: fix handling of fbcon colours in 8bpp
Depending on the visual, the colours handed to us in fillrect() can either be
an actual colour, or an index into the pseudo-palette.

Subject: [PATCH 0741/1816] drm/nv50: prevent a possible ctxprog hang
The below is mainly an educated guess at what's going on, docs would
sure be handy... NVIDIA? :P
It appears it's possible for a ctxprog to run even while a GPU exception
is pending. The GF8 and up ctxprogs appear to have a small snippet of
code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:
if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}
I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us). This patch causes the driver to
clear the flag during the PGRAPH IRQ handler.

Subject: [PATCH 0742/1816] drm/nouveau: Fix null deref in nouveau_fence_emit
due to deleted fence
Currently Nouveau will unvalidate all buffers if it is forced to wait on
one, and then start revalidating from the beginning. While doing so, it
destroys the operation fence, causing nouveau_fence_emit to crash.
This patch fixes this bug by taking the fence object out of validate_op
and creating it just before emit. The fence pointer is initialized to 0
and unref'ed unconditionally.
In addition to fixing the bug, this prevents its reintroduction and
simplifies the code.

While investigating a kmemleak detected leak, I encountered the
agp_add_bridge function. It appears to be responsible for freeing
the agp_bridge_data in the case of a failure, but it is only doing
so for some errors.
Fix it to always free the bridge data if a failure condition is
encountered.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 15b8dd53f5ffa changed the string in info->hardware_id from a static
array to a pointer and added a length field. But instead of changing
"sizeof(array)" to "length", we changed it to "sizeof(length)" (== 4),
which corrupts the string we're trying to null-terminate.
We no longer even need to null-terminate the string, but we *do* need to
check whether we found a HID. If there's no HID, we used to have an empty
array, but now we have a null pointer.
The combination of these defects causes this oops:
Unable to handle kernel NULL pointer dereference (address 0000000000000003)

Bail out if we don't find an enclosing IOC. Previously, if we didn't
find one, we tried to set things up using garbage for the SBA/IOC register
address, which causes a crash.
This crash only happens if firmware supplies a defective ACPI namespace, so
it doesn't fix any problems in the field.

Subject: [PATCH 0757/1816] quota: Fix dquot_transfer for filesystems different
from ext4
Commit fd8fbfc1 modified the way we find amount of reserved space
belonging to an inode. The amount of reserved space is checked
from dquot_transfer and thus inode_reserved_space gets called
even for filesystems that don't provide get_reserved_space callback
which results in a BUG.
Fix the problem by checking get_reserved_space callback and return 0 if
the filesystem does not provide it.

Subject: [PATCH 0763/1816] block: Correct handling of bottom device
misaligment
The top device misalignment flag would not be set if the added bottom
device was already misaligned as opposed to causing a stacking failure.
Also massage the reporting so that an error is only returned if adding
the bottom device caused the misalignment. I.e. don't return an error
if the top is already flagged as misaligned.

Subject: [PATCH 0772/1816] ARM: 5874/1: serial21285: fix
disable_irq-from-interrupt-handler deadlock
The console hangs during bootup when disable_irq is called from the
transmit interrupt handler (it will wait forever for it's "own"
interrupt in synchronize_irq). Fix by using disable_irq_nosync()
instead.

Subject: [PATCH 0775/1816] kmemcheck: make bitfield annotations truly no-ops
when disabled
It turns out that even zero-sized struct members (int foo[0];) will affect
the struct layout, causing us in particular to lose 4 bytes in struct
sock.
This patch fixes the regression in CONFIG_KMEMCHECK=n case.

Subject: [PATCH 0777/1816] kmod: fix resource leak in
call_usermodehelper_pipe()
Fix resource (write-pipe file) leak in call_usermodehelper_pipe().
When call_usermodehelper_exec() fails, write-pipe file is opened and
call_usermodehelper_pipe() just returns an error. Since it is hard for
caller to determine whether the error occured when opening the pipe or
executing the helper, the caller cannot close the pipe by themselves.
I've found this resoruce leak when testing coredump. You can check how
the resource leaks as below;
$ echo "|nocommand" > /proc/sys/kernel/core_pattern
$ ulimit -c unlimited
$ while [ 1 ]; do ./segv; done &> /dev/null &
$ cat /proc/meminfo (<- repeat it)
where segv.c is;
//-----
int main () {
char *p = 0;
*p = 1;
}
//-----
This patch closes write-pipe file if call_usermodehelper_exec() failed.

Subject: [PATCH 0779/1816] zlib: optimize inffast when copying direct from
output
JFFS2 uses lesser compression ratio and inflate always ends up in "copy
direct from output" case.
This patch tries to optimize the direct copy procedure. Uses
get_unaligned() but only in one place.
The copy loop just above this one can also use this optimization, but I
havn't done so as I have not tested if it is a win there too.
On my MPC8321 this is about 17% faster on my JFFS2 root FS than the
original.

Subject: [PATCH 0780/1816] lib: add support for LZO-compressed kernels
This patch series adds generic support for creating and extracting
LZO-compressed kernel images, as well as support for using such images on
the x86 and ARM architectures, and support for creating and using
LZO-compressed initrd and initramfs images.
Russell King said:
: Testing on a Cortex A9 model:
: - lzo decompressor is 65% of the time gzip takes to decompress a kernel
: - lzo kernel is 9% larger than a gzip kernel
:
: which I'm happy to say confirms your figures when comparing the two.
:
: However, when comparing your new gzip code to the old gzip code:
: - new is 99% of the size of the old code
: - new takes 42% of the time to decompress than the old code
:
: What this means is that for a proper comparison, the results get even better:
: - lzo is 7.5% larger than the old gzip'd kernel image
: - lzo takes 28% of the time that the old gzip code took
:
: So the expense seems definitely worth the effort. The only reason I
: can think of ever using gzip would be if you needed the additional
: compression (eg, because you have limited flash to store the image.)
:
: I would argue that the default for ARM should therefore be LZO.
This patch:
The lzo compressor is worse than gzip at compression, but faster at
extraction. Here are some figures for an ARM board I'm working on:
Uncompressed size: 3.24Mo
gzip 1.61Mo 0.72s
lzo 1.75Mo 0.48s
So for a compression ratio that is still relatively close to gzip, it's
much faster to extract, at least in that case.
This part contains:
- Makefile routine to support lzo compression
- Fixes to the existing lzo compressor so that it can be used in
compressed kernels
- wrapper around the existing lzo1x_decompress, as it only extracts one
block at a time, while we need to extract a whole file here
- config dialog for kernel compression

Subject: [PATCH 0786/1816] cgroups: fix 2.6.32 regression causing BUG_ON() in
cgroup_diput()
The LTP cgroup test suite generates a "kernel BUG at kernel/cgroup.c:790!"
here in cgroup_diput():
/*
* if we're getting rid of the cgroup, refcount should ensure
* that there are no pidlists left.
*/
BUG_ON(!list_empty(&cgrp->pidlists));
The cgroup pidlist rework in 2.6.32 generates the BUG_ON, which is caused
when pidlist_array_load() calls cgroup_pidlist_find():
(1) if a matching cgroup_pidlist is found, it down_write's the mutex of the
pre-existing cgroup_pidlist, and increments its use_count.
(2) if no matching cgroup_pidlist is found, then a new one is allocated, it
down_write's its mutex, and the use_count is set to 0.
(3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(),
which increments its use_count -- regardless whether new or pre-existing --
and up_write's the mutex.
So if a matching list is ever encountered by cgroup_pidlist_find() during
the life of a cgroup directory, it results in an inflated use_count value,
preventing it from ever getting released by cgroup_release_pid_array().
Then if the directory is subsequently removed, cgroup_diput() hits the
BUG_ON() when it finds that the directory's cgroup is still populated with
a pidlist.
The patch simply removes the use_count increment when a matching pidlist
is found by cgroup_pidlist_find(), because it gets bumped by the calling
pidlist_array_load() function while still protected by the list's mutex.

When print-fatal-signals is enabled it's possible to dump any memory
reachable by the kernel to the log by simply jumping to that address from
user space.
Or crash the system if there's some hardware with read side effects.
The fatal signals handler will dump 16 bytes at the execution address,
which is fully controlled by ring 3.
In addition when something jumps to a unmapped address there will be up to
16 additional useless page faults, which might be potentially slow (and at
least is not very efficient)
Fortunately this option is off by default and only there on i386.
But fix it by checking for kernel addresses and also stopping when there's
a page fault.

Subject: [PATCH 0789/1816] proc: partially revert "procfs: provide stack
information for threads"
Commit d899bf7b (procfs: provide stack information for threads) introduced
to show stack information in /proc/{pid}/status. But it cause large
performance regression. Unfortunately /proc/{pid}/status is used ps
command too and ps is one of most important component. Because both to
take mmap_sem and page table walk are heavily operation.
If many process run, the ps performance is,
[before d899bf7b]
% perf stat ps >/dev/null
Performance counter stats for 'ps':
4090.435806 task-clock-msecs # 0.032 CPUs
229 context-switches # 0.000 M/sec
0 CPU-migrations # 0.000 M/sec
234 page-faults # 0.000 M/sec

[after d899bf7b]
% perf stat ps > /dev/null
Performance counter stats for 'ps':
4305.081146 task-clock-msecs # 0.028 CPUs
480 context-switches # 0.000 M/sec
2 CPU-migrations # 0.000 M/sec

23917502 cache-misses # 5.556 M/sec
152.277819582 seconds time elapsed
Thus, this patch revert it. Fortunately /proc/{pid}/task/{tid}/smaps
provide almost same information. we can use it.
Commit d899bf7b introduced two features:
1) Add the annotattion of [thread stack: xxxx] mark to
/proc/{pid}/task/{tid}/maps.
2) Add StackUsage field to /proc/{pid}/status.
I only revert (2), because I haven't seen (1) cause regression.

Subject: [PATCH 0791/1816] mmc_block: add dev_t initialization check
When a card is removed before mmc_blk_probe() has called add_disk(), then
the minor field is uninitialized and has value 0. This caused
mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then
the next mmc_blk_probe() used the first free idx of 0, which oopses in
sysfs, since it is used by another card.

Subject: [PATCH 0793/1816] mmc_block: fix queue cleanup
The main bug was that 'blk_cleanup_queue()' was called while the block
device could still be in use, for example, because the card was removed
while files were still open.
In addition, to be sure that 'mmc_request()' will get called for all new
requests (so it can error them out), the queue is emptied during cleanup.
This is done after the worker thread is stopped to avoid racing with it.
Finally, it is not a device error for this to be happening, so quiet the
(sometimes very many) error messages.

Found by sparse, which I should've run much earlier.

+
+Description
+-----------
+
+This driver implements support for the Texas Instruments amc6821 chip.
+The chip has one on-chip and one remote temperature sensor and one pwm fan
+regulator.
+The pwm can be controlled either from software or automatically.
+
+The driver provides the following sensor accesses in sysfs:
+
+temp1_input ro on-chip temperature
+temp1_min rw "
+temp1_max rw "
+temp1_crit rw "
+temp1_min_alarm ro "
+temp1_max_alarm ro "
+temp1_crit_alarm ro "
+
+temp2_input ro remote temperature
+temp2_min rw "
+temp2_max rw "
+temp2_crit rw "
+temp2_min_alarm ro "
+temp2_max_alarm ro "
+temp2_crit_alarm ro "
+temp2_fault ro "
+
+fan1_input ro tachometer speed
+fan1_min rw "
+fan1_max rw "
+fan1_fault ro "
+fan1_div rw Fan divisor can be either 2 or 4.
+
+pwm1 rw pwm1
+pwm1_enable rw regulator mode, 1=open loop, 2=fan controlled
+ by remote temperature, 3=fan controlled by
+ combination of the on-chip temperature and
+ remote-sensor temperature,
+pwm1_auto_channels_temp ro 1 if pwm_enable==2, 3 if pwm_enable==3
+pwm1_auto_point1_pwm ro Hardwired to 0, shared for both
+ temperature channels.
+pwm1_auto_point2_pwm rw This value is shared for both temperature
+ channels.
+pwm1_auto_point3_pwm rw Hardwired to 255, shared for both
+ temperature channels.
+
+temp1_auto_point1_temp ro Hardwired to temp2_auto_point1_temp
+ which is rw. Below this temperature fan stops.
+temp1_auto_point2_temp rw The low-temperature limit of the proportional
+ range. Below this temperature
+ pwm1 = pwm1_auto_point2_pwm. It can go from
+ 0 degree C to 124 degree C in steps of
+ 4 degree C. Read it out after writing to get
+ the actual value.
+temp1_auto_point3_temp rw Above this temperature fan runs at maximum
+ speed. It can go from temp1_auto_point2_temp.
+ It can only have certain discrete values
+ which depend on temp1_auto_point2_temp and
+ pwm1_auto_point2_pwm. Read it out after
+ writing to get the actual value.
+
+temp2_auto_point1_temp rw Must be between 0 degree C and 63 degree C and
+ it defines the passive cooling temperature.
+ Below this temperature the fan stops in
+ the closed loop mode.
+temp2_auto_point2_temp rw The low-temperature limit of the proportional
+ range. Below this temperature
+ pwm1 = pwm1_auto_point2_pwm. It can go from
+ 0 degree C to 124 degree C in steps
+ of 4 degree C.
+
+temp2_auto_point3_temp rw Above this temperature fan runs at maximum
+ speed. It can only have certain discrete
+ values which depend on temp2_auto_point2_temp
+ and pwm1_auto_point2_pwm. Read it out after
+ writing to get actual value.
+
+
+Module parameters
+-----------------
+
+If your board has a BIOS that initializes the amc6821 correctly, you should
+load the module with: init=0.
+
+If your board BIOS doesn't initialize the chip, or you want
+different settings, you can set the following parameters:
+init=1,
+pwminv: 0 default pwm output, 1 inverts pwm output.

Subject: [PATCH 0803/1816] smaps: fix wrong rss count
A long time ago we regarded zero page as file_rss and vm_normal_page
doesn't return NULL.
But now, we reinstated ZERO_PAGE and vm_normal_page's implementation can
return NULL in case of zero page. Also we don't count it with file_rss
any more.
Then, RSS and PSS can't be matched. For consistency, Let's ignore zero
page in smaps_pte_range.

commit abd6633c67925f90775bb74755f9c547e30f1f20 ("pnp: add a shutdown
method to pnp drivers") adds shutdown method to bus driver blindly. With
it, driver->shutdown is no longer valid.
Use pnp_driver->shutdown instead.

Subject: [PATCH 0805/1816] mn10300: signal stack fix
This fixes a signal stack handling problem in the MN10300 arch. When new
threads are cloned with CLONE_VM, they don't inherit the alternate signal
stack. They do share the signal flags, though. When deciding whether to
use an alternate stack, the arch code needs to check to make sure the task
struct contains a valid alternate stack. This patch fixes the MN10300
arch by using the sas_ss_flags() test provided by sched.h rather than the
on_sig_stack() test which is insufficient by itself.

Subject: [PATCH 0807/1816] mn10300: add cc clobbers to asm statements
gcc 4.2.1 for MN10300 is more agressive than the older gcc in
reordering/moving other insns between an insn that sets flags and an insn
that uses those flags. This leads to trouble with asm statements which
are missing an explicit "cc" clobber. This patch adds the explicit "cc"
clobber to asm statements which do indeed clobber the condition flags.

Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- checks PCI_NUM_RESOURCES (11), not 6, resources
- skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"

Subject: [PATCH 0812/1816] mn10300: insert PCI root bus resources for the
ASB2305 devel motherboard
Insert PCI root bus resources for the MN10300-based ASB2305 development
kit motherboard. This is required because the CPU's window onto the PCI
bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want
to access.
Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.
We also add a reservation for the PCI SRAM region.

Subject: [PATCH 0813/1816] mn10300: make the ASB2305's PCnet32 NIC work by
using the PCI bridge's SRAM
Access to the ASB2305's PCnet32 NIC doesn't work correctly because when
the NIC attempts to update the ring buffer flags by DMA, the change to RAM
crops up about 17uS after the interrupt line is asserted. This is almost
certainly due to a bug in the PCI bridge FPGA on that board.
We can get around this by making dma_alloc_coherent() put the ring buffer
in the SRAM attached to the PCI bridge rather than in the SDRAM.

Subject: [PATCH 0815/1816] core, x86: make LIST_POISON less deadly
The list macros use LIST_POISON1 and LIST_POISON2 as undereferencable
pointers in order to trap erronous use of freed list_heads. Unfortunately
userspace can arrange for those pointers to actually be dereferencable,
potentially turning an oops to an expolit.
To avoid this allow architectures (currently x86_64 only) to override
the default values for these pointers with truly-undereferencable values.
This is easy on x86_64 as the virtual address space is large and contains
areas that cannot be mapped.
Other 64-bit architectures will likely find similar unmapped ranges.
[ingo: switch to 0xdead000000000000 as the unmapped area]
[ingo: add comments, cleanup]

Subject: [PATCH 0816/1816] iwlwifi: silence buffer overflow warning
Smatch (and presumably other static checkers) complain that MAX_TID_COUNT is
past the end of the array. In the resulting discussion, Zhu Yi pointed out
that this value is not used in real life and the assignment was only there to
silence a gcc warning.
If there were a bug in the surrounding code and the value were used, the
WARN_ON(!qc) would print a warning before the crash.

Subject: [PATCH 0819/1816] tcp: Generalized TTL Security Mechanism
This patch adds the kernel portions needed to implement
RFC 5082 Generalized TTL Security Mechanism (GTSM).
It is a lightweight security measure against forged
packets causing DoS attacks (for BGP).
This is already implemented the same way in BSD kernels.
For the necessary Quagga patch
http://www.gossamer-threads.com/lists/quagga/dev/17389
Description from Cisco
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt_btsh.html
It does add one byte to each socket structure, but I did
a little rearrangement to reuse a hole (on 64 bit), but it
does grow the structure on 32 bit
This should be documented on ip(4) man page and the Glibc in.h
file also needs update. IPV6_MINHOPLIMIT should also be added
(although BSD doesn't support that).
Only TCP is supported, but could also be added to UDP, DCCP, SCTP
if desired.

Subject: [PATCH 0820/1816] mac80211: fix queue selection for data frames on
monitor interfaces
When ieee80211_monitor_select_queue encounters data frames, it selects
the WMM AC based on skb->priority and assumes that skb->priority
contains a valid 802.1d tag. However this assumption is incorrect, since
ieee80211_select_queue has not been called at this point.
If skb->priority > 7, an array overrun occurs, which could lead to
invalid values, resulting in crashes in the tx path.
Fix this by setting skb->priority based on the 802.11 header for QoS
frames and using the default AC for all non-QoS frames.

disabled
When CONFIG_CFG80211_WEXT is not set, there is
a refcount imbalance with rdev->opencount, fix
that by moving it out of the ifdef.

Subject: [PATCH 0822/1816] Revert "x86, apic: Use logical flat on intel with
<= 8 logical cpus"
Revert commit 2fbd07a5f5d1295fa9b0c0564ec27da7c276a75a, as this commit
breaks an IBM platform with quad-core Xeon cpu's.
According to Suresh, this might be an IBM platform issue, as on other
Intel platforms with <= 8 logical cpu's, logical flat mode works fine
irespective of physical apic id values (inline with the xapic
architecture).
Revert this for now because of the IBM platform breakage.
Another version will be re-submitted after the complete analysis.

Subject: [PATCH 0829/1816] OMAP: DSS2: OMAPFB: fix crash when panel driver was
not loaded
If the panel's probe had failed, omapfb would still go on, eventually
crashing.
A better fix would be to handle each display properly, and leaving just
the failed display out. But that is a bigger change.

Subject: [PATCH 0830/1816] sky2: Fix oops in sky2_xmit_frame() after TX
timeout
During TX timeout procedure dev could be awoken too early, e.g. by
sky2_complete_tx() called from sky2_down(). Then sky2_xmit_frame()
can run while buffers are freed causing an oops. This patch fixes it
by adding netif_device_present() test in sky2_tx_complete().

o Remove the .initrd section. The initrd section was already handled

o Discard .MIPS.options, .options, .pdr, .reginfo, .comment and .note
sections. If .MIPS.options is not removed, kernels compiled with gcc
3.4.6 will not boot.
o Clean up the file format.
o Remove several other unneeded sections.
Tested with GCC 3.4.6 and 4.4.1 with and without initrd.

Subject: [PATCH 0843/1816] MIPS: TXx9: Cleanup builtin-cmdline processing
Since commit 898d357b5262f9e26bc2418e01f8676e80d9867e (lmo) /
6acc7d485c24c00e111c61b2e6dff9180faebcae (kernel.org) ("Fix and enhance
built-in kernel command line") arcs_cmdline[] does not contain built-in
command line. The commit introduce CONFIG_CMDLINE_BOOL and
CONFIG_CMDLINE_OVERRIDE to control built-in command line, and now we can
use them instead of platform-specific built-in command line processing.

Subject: [PATCH 0844/1816] MIPS: Octeon: Add sched_clock() to csrc-octeon.c
With the advent of function graph tracing on MIPS, Octeon needs a high
precision sched_clock() implementation. Without it, most timing
numbers are reported as 0.000.
This new sched_clock just uses the 64-bit cycle counter appropriately
scaled.

Subject: [PATCH 0851/1816] MIPS: cpumask_of_node() should handle -1 as a node
pcibus_to_node can return -1 if we cannot determine which node a pci bus
is on. If passed -1, cpumask_of_node will negatively index the lookup array
and pull in random data:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
00000000,00000003,00000000,00000000
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist
64-65
Change cpumask_of_node to check for -1 and return cpu_all_mask in this
case:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
ffffffff,ffffffff,ffffffff,ffffffff

that number is "worth" only 32 bits when kernel advances by 64 bits.
Fix that by ensuring that output produced for compat tasks uses 32-bit units.

Subject: [PATCH 0855/1816] ath9k: re-enable ps by default for new single chip
families
The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.
For more details on this issue see the bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=14267
We leave AR5416 with PS disabled by default, that seems to require
some more work.

Subject: [PATCH 0856/1816] nl80211: Add new WIPHY attribute COVERAGE_CLASS
The new attribute NL80211_ATTR_WIPHY_COVERAGE_CLASS sets IEEE 802.11
Coverage Class, which depends on maximum distance of nodes in a
wireless network. It's required for long distance links (more than a few
hundred meters).
The attribute is now ignored by two non-mac80211 drivers, rndis and
iwmc3200wifi, together with WIPHY_PARAM_RETRY_SHORT and
WIPHY_PARAM_RETRY_LONG. If it turns out to be a problem, we could split
set_wiphy_params callback or add new capability bits.

Functions ath5k_hw_get_slot_time and ath5k_hw_set_slot_time were
converting microseconds to clocks only for AR5210, although it's needed
for all supported devices. The conversion was moved outside the
hardware-specific branches.
The original code also limited minimum slot time to 9, while turbo modes
use 6, this was fixed too.

Subject: [PATCH 0859/1816] ath5k: Reimplement clock rate to usec conversion
The original code was correct in 802.11a mode only, 802.11b/g uses
different clock rates. The new code uses values taken from FreeBSD HAL
and should be correct for all modes including turbo modes.
The former rate calculation was used by slope coefficient calculation
function ath5k_hw_write_ofdm_timings. However, this function requires
the 802.11a values even in 802.11g mode. Thus the use of
ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope
coefficient calculation is not related to clock rate at all.

Subject: [PATCH 0860/1816] ath5k: Implement mac80211 callback
set_coverage_class
The callback sets slot time as specified in IEEE 802.11-2007 section
17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS
timeouts accordingly. The values are persistent, they are restored after
device reset.

will quit. Otherwise when suspend happens before the timer expired,
the timer handler will be called immediately after resume and
messes up driver status.

Subject: [PATCH 0862/1816] mac80211: Select lowest rate based on basic rate
set in AP mode
If the basic rate set is configured to not include the lowest rate
(e.g., basic rate set = 6, 12, 24 Mbps in IEEE 802.11g mode), the AP
should not send out broadcast frames at 1 Mbps. This type of
configuration can be used to optimize channel usage in cases where
there is no need for backwards compatibility with IEEE 802.11b-only
devices.
In AP mode, mac80211 was unconditionally using the lowest rate for
Beacon frames and similarly, with all rate control algorithms that use
rate_control_send_low(), the lowest rate ended up being used for all
broadcast frames (and all unicast frames that are sent before
association). Change this to take into account the basic rate
configuration in AP mode, i.e., use the lowest rate in the basic rate
set instead of the lowest supported rate when selecting the rate.

From 37eb0b164cf9fa9f70c8500926f5cde7c652f48e Mon Sep 17 00:00:00 2001
From: Jouni Malinen <jouni.malinen@atheros.com>
Date: Wed, 6 Jan 2010 13:09:08 +0200
Subject: [PATCH 0863/1816] cfg80211/mac80211: Use more generic bitrate mask
for rate control
Extend struct cfg80211_bitrate_mask to actually use a bitfield mask
instead of just a single fixed or maximum rate index. This change
itself does not modify the behavior (except for debugfs files), but it
prepares cfg80211 and mac80211 for a new nl80211 command for setting
which rates can be used in TX rate control.
Since frames are now going through the rate control algorithm
unconditionally, the internal IEEE80211_TX_INTFL_RCALGO flag can now
be removed. The RC implementations can use the rate_idx_mask value to
optimize their behavior if only a single rate is enabled.
The old max_rate_idx in struct ieee80211_tx_rate_control is maintained
(but commented as deprecated) for backwards compatibility with existing
RC implementations. Once these implementations have been updated to
use the more generic rate_idx_mask, the max_rate_idx value can be
removed.

Subject: [PATCH 0864/1816] nl80211: New command for setting TX rate mask for
rate control
Add a new NL80211_CMD_SET_TX_BITRATE_MASK command and related
attributes to provide support for setting TX rate mask for rate
control. This uses the existing cfg80211 set_bitrate_mask operation
that was previously used only with WEXT compat code (SIOCSIWRATE). The
nl80211 command allows more generic configuration of allowed rates as
a mask instead of fixed/max rate.

Subject: [PATCH 0865/1816] rt2x00: RF3052 is a valid RF chipset for USB
devices as well.
The RF3052 chipset is now also being integrated onto USB devices, so
allow the RF chipset and don't treat it as PCI/SOC only.

Subject: [PATCH 0868/1816] mac80211: add functions to create PS Poll and
Nullfunc templates
Some hardware, for example wl1251 and wl1271, handle the transmission
of power save related frames in hardware, but the driver is responsible
for creating the templates. It's better to create the templates in mac80211,
that way all drivers can benefit from this.
Add two new functions, ieee80211_pspoll_get() and ieee80211_nullfunc_get()
which drivers need to call to get the frame. Drivers are also responsible
for updating the templates after each association.
Also new struct ieee80211_hdr_3addr is added to ieee80211.h to make it
easy to calculate length of the Nullfunc frame.

Subject: [PATCH 0872/1816] mac80211: use Probe Request template when sending a
direct scan
As mac80211 now has a separate function for creating Probe Request templates,
better to use it when sending direct Probe Requests to an AP. Only the
bssid needs to be updated in the template before sending it.

Subject: [PATCH 0873/1816] wl1251: cleanup scanning code
The current scanning code wasn't following the preferred style. Move code
related to scan and trigger scan to commans to wl1251_cmd.c. Because
there's now less code in wl1251_hw_scan(), the function can be now
merged with wl1251_op_hw_scan().

Subject: [PATCH 0876/1816] wl1251: fix sleep related error paths in
wl1251_op_bss_info_changed()
In various cases wl1251_op_bss_info_changed() did not call elp_sleep()
after an error was noticed. Fix it by using correct goto label.
The bug was a theoretical one, in practise it doesn't matter because
if commands start returning errors there will be lots of other problems.

Subject: [PATCH 0877/1816] cfg80211: Store IEs from both Beacon and Probe
Response frames
Store information elements from Beacon and Probe Response frames in
separate buffers to allow both sets to be made available through
nl80211. This allows user space applications to get access to IEs from
Beacon frames even if we have received Probe Response frames from the
BSS. Previously, the IEs from Probe Response frames would have
overridden the IEs from Beacon frames.
This feature is of somewhat limited use since most protocols include
the same (or extended) information in Probe Response frames. However,
there are couple of exceptions where the IEs from Beacon frames could
be of some use: TIM IE is only included in Beacon frames (and it would
be needed to figure out the DTIM period used in the BSS) and at least
some implementations of Wireless Provisioning Services seem to include
the full IE only in Beacon frames).
The new BSS attribute for scan results is added to allow both the IE
sets to be delivered. This is done in a way that maintains the
previously used behavior for applications that are not aware of the
new NL80211_BSS_BEACON_IES attribute.

Subject: [PATCH 0878/1816] mac80211: fix a few work bugs
Kalle and Lennert reported problems with the new work
code, and at least Kalle's problem I was able to trace
to a missing jiffies initialisation.
I also ran into a problem where occasionally I couldn't
connect, which seems fixed with kicking the work items
after scanning.
Finally, also add some sanity checking code to verify
that we're not adding work items while an interface is
down -- that case could lead to something similar to
what Lennert was seeing.
There still seems to be a race condition that we're
trying to figure out separately.

Subject: [PATCH 0881/1816] cfg80211: process the max power on a country IE
The max power from each country IE triplet was being ignored.
This fix isn't critical as CRDA was always being used for the lower
limit, but we should process it in case the AP still wants to
decrease power output even more for whatever reason.

Subject: [PATCH 0882/1816] cfg80211: Fix country IE parsing for single channel
triplets
This enhances the way we parse country IEs to minimize
the number of regulatory rules that we create. It also fixes
our current implementation which treated country IE triplets
with only one channel as one independed regulatory rule even
though adjecent rules were also being provided.
Without this patch APs which send country IE information with
a channel triplet for each individual channel will force cfg80211
to deny HT40 operation as a regulatory rule would have been created
independently for each channel and as such configured only for
20 MHz operation.
Although 802.11n APs which send country IEs triplets in this fassion
are likely rare Benoit reports this against the Ubiquity NanoStation M5,
with Country "FR" and HT40 enabled.
Since we now have a helper which parses the triplets in intermediate
steps we now take care extra care to process padding.

Subject: [PATCH 0884/1816] ARM: Fix wrong dmb
The __kuser_cmpxchg code uses an ARMv6 dmb instruction, rather than
one based upon the architecture being built for. Switch to using
the macro provided for this purpose, which also eliminates the
need for an ifdef.

Subject: [PATCH 0888/1816] ARM: Ensure ARMv6/7 mm files are built using
appropriate assembler options
A kernel with both ARMv6 and ARMv7 selected results in build errors.
Fix this by specifying the proper architectures for these assembly
files.

Subject: [PATCH 0892/1816] mac80211: use nullfunc frames for 4-addr sta
detection
To detect incoming 4-addr stations, hostapd needs to receive a 4-addr
data frame from the remote station, so that it can create the AP VLAN
for it. With this patch, the mlme code emits a 4-addr nullfunc frame
immediately after assoc. On the AP side it also drops 4-addr nullfunc
frames to the cooked monitor mode interface, if the interface hasn't
been fully set up to receive 4-addr data frames yet.

Subject: [PATCH 0893/1816] mac80211: allow station updates on ap interfaces
for vlan stations
Since the per-vif station changes, sta_info_get on the ap sdata no
longer returns entries for stations on ap vlans. This causes issues
with hostapd, which currently always passes the ap interface name to
nl80211 calls. This patch provides bug compatibility with the earlier
versions until hostapd is fixed.

Subject: [PATCH 0897/1816] mwl8k: bump the transmit wait timeout to 5 seconds
While it is reasonable to expect that at least one transmit ring entry
will be processed per second while we are waiting for the transmit
rings to drain, the firmware can end up doing batching of transmit ring
status writeback, which means that the transmit rings can appear stuck
for more than a second at a time.
Bump the TX drain wait timeout up from 1 to 5 seconds to account for
this.

Subject: [PATCH 0898/1816] mwl8k: simplify mwl8k_cmd_use_fixed_rate()
As we always use the auto rate adaptation feature and never pass in
a rate table, USE_FIXED_RATE can be simplified somewhat. While we're
at it, rename it to *_sta, as this is the STA version of the command.

Subject: [PATCH 0900/1816] mwl8k: implement AP firmware station database
maintenance
STA firmware uses UPDATE_STADB to manipulate the hardware station
database, whereas AP firmware uses SET_NEW_STN -- this implements the
latter, and hooks it into mwl8k_sta_notify(), to be used if we're
running on AP firmware.

Subject: [PATCH 0904/1816] mwl8k: keep TX_DONE interrupt masked while transmit
reclaim is running
By making use of the CLEAR_SEL feature of the mwl8k host interface
interrupt controller, we can keep the TX_DONE interrupt source masked
while the transmit reclaim tasklet is running (NAPI style) without
having to touch the interrupt controller's interrupt mask register
when entering or exiting polling mode, and without having to do any
more register reads/writes than we do now.
When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading
the interrupt status register will clear the TX_DONE status bit if
it was set, allowing it to be set again if a new TX_DONE event arrives
while we are running the TX reclaim tasklet, but such a new event will
then not trigger another PCI interrupt until a zero is written to the
TX_DONE interrupt status register bit.
I.e., if we write a zero to the TX_DONE interrupt source bit in the
interrupt status register when the TX reclaim tasklet thinks it's
done, a PCI interrupt will be triggered if a new TX_DONE event arrived
from the hardware between us deciding that there is no more work to do
and re-enabling the TX_DONE interrupt source, thereby avoiding the
classic NAPI poll mode exit race that would otherwise occur.

Subject: [PATCH 0905/1816] mwl8k: move receive processing to tasklet
Like how TX reclaim is done in a tasklet, move receive processing
to tasklet context as well. This can have nice benefits for CPU
utilisation and throughput, especially at 3-stream rates.
(Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to
avoid having to touch the interrupt mask registers.)

Subject: [PATCH 0906/1816] mac80211: fix return from ieee80211_assoc_success
sparse pointed out that I made a mistake converting
the return value of ieee80211_assoc_success to bool,
this place should return false instead of one of the
enum values (which would be true).

Subject: [PATCH 0907/1816] iwlwifi: add IEEE80211_AMPDU_TX_OPERATIONAL
mac80211 do not check the return code now, what if mac80211 does start
using the return code? IEEE80211_AMPDU_TX_OPERATIONAL is a valid action,
just iwlwifi driver do not need to take any action for it; so instead of
return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP"
to make sure mac80211 will not get wrong impression.

Subject: [PATCH 0913/1816] mac80211: flush workqueue before calling driver
->stop() method
Since commit "mwl8k: handle station database update for AP's sta entry
via ->sta_notify()", mwl8k every now and then gets a command timeout
when ifconfig'ing a STA interface down. This turns out to be due to
mwl8k_stop() being called while the work queue item that was scheduled
by mwl8k_sta_notify() to remove the STA entry for the associated AP is
still queued, and the former disables interrupts so that when the
latter eventually runs, a command completion interrupt is never seen.
Fix this by changing ieee80211_stop_device() so that the workqueue is
flushed before drv_stop() is called, instead of doing it the other way
around as is done now. (As ->stop() is allowed to sleep, there isn't
any reason for drivers to queue work from within it.)

Subject: [PATCH 0915/1816] mac80211: add U-APSD client support
Add Unscheduled Automatic Power-Save Delivery (U-APSD) client support. The
idea is that the data frames from the client trigger AP to send the buffered
frames with ACs which have U-APSD enabled. This decreases latency and makes it
possible to save even more power.
Driver needs to use IEEE80211_HW_UAPSD to enable the feature. The current
implementation assumes that firmware takes care of the wakeup and
hardware needing IEEE80211_HW_PS_NULLFUNC_STACK is not yet supported.
Tested with wl1251 on a Nokia N900 and Cisco Aironet 1231G AP and running
various test traffic with ping.

Subject: [PATCH 0917/1816] mac80211: create tx handler for dynamic ps
Currently dynamic ps check is in ieee80211_xmit(), but it's cleaner
to have a separate tx handler for this. Also this is a prerequisite for
U-APSD client mode which needs to know the queue frame is in.
Also need_dynamic_ps() function is embedded to the tx handler.
No functional changes expect that the code is run in a later phase than
originally.

Subject: [PATCH 0918/1816] mac80211: check uapsd state for dynamic power save
To make U-APSD client mode effective, we must not wake up from dynamic power
save when transmitting frames. So if dynamic power save is enabled, it needs
check the queue the transmitted packet is in and decide if we need to wake
up or not.
In a perfect world, where all packets would have correct QoS tags, U-APSD
enabled queues should not trigger wakeup from power save. But in the real
world, where very few packets have correct QoS tags, this won't work. For
example, if only voip class has U-APSD enabled and we send a packet in voip
class, but the packets we receive are in best effort class, we would receive
the packets with the legacy power save method. And that would increase
latencies too much from a voip application point of view.
The workaround is to enable U-APSD for all qeueus and still use dynamic ps
wakeup for all other queues except voip. That way we can still save power
with a voip application and not sacrifice latency. Normal traffic (in
background, best effort or video class) would still trigger wakeup from
dynamic power save.

Subject: [PATCH 0930/1816] mwl8k: properly set receive status rate index on 5
GHz receive
The mwl8k firmware uses indices into the 2.4 GHz band rate table for
the receive descriptor channel field even if the packet was received
on a 5 GHz channel, while mac80211 expects an index into the 5 GHz
band rate table when packets are received on the 5 GHz band, which
presents a mismatch as the 5 GHz band rate table lacks the five
non-OFDM rates that the 2.4 GHz rate table starts with.
To handle this properly, we need to substract 5 from the rate index
field if the packet was received on a 5 GHz channel (and was not
received at an MCS rate).

Subject: [PATCH 0931/1816] mwl8k: handle 5 GHz legacy rate bitmaps in firmware
commands
Whenever mac80211 gives us a legacy rate bitmap in the context of the
5 GHz band, we need to remember to shift the bitmap left by 5 positions
before giving it to the firmware, as the firmware follows the bitmap
bit assignment of the 2.4 GHz rate table even if we're on the 5 GHz
band, and the 2.4 GHz rate table includes five non-OFDM rates at the
start that are not valid in the 5 GHz band.

Subject: [PATCH 0935/1816] mwl8k: prepare for posting per-vif firmware
commands
One of the bytes in the mwl8k firmware command header is the 'macid'
byte, which for per-vif commands indicates which of the BSSes this
command is intended for. (For commands that are not per-vif commands,
this byte can just be 0.)
This patch adds mwl8k_post_pervif_cmd(), which will take the macid
assigned to this interface (to be done in ->add_interface()), copy it
into the command packet macid field, and post the command as usual.

Subject: [PATCH 0936/1816] mwl8k: post per-vif firmware commands as per-vif
commands
SET_BEACON, SET_MAC_ADDR, BSS_START and SET_NEW_STN are the currently
supported firmware commands that are actually per-vif commands. Use
mwl8k_post_pervif_cmd() for these commands, so that the macid of the
vif they operate on gets passed down into the firmware.

Subject: [PATCH 0937/1816] mwl8k: enable multi-BSS AP operation
As follows:
- GET_HW_SPEC is now responsible for setting
priv->{ap,sta}_macids_supported, which are bitmasks of supported
macids for AP and STA mode. (Typically, STA firmware images will
support only one macid, #0, in STA mode, and AP firmware images
will support macids #0-7, in AP mode.)
- Our wiphy ->interfaces_modes is now set based on the non-zero-ness
of these two bitmasks.
- We main priv->macids_used, a bitmask of which macids are currently
in use. ->add_interface() will assign the lowest free macid for
this interface type as it is created, or bail out if there are no
more free macids to assign. ->delete_interface() will mark the
macid as being free again.
This enables the multi-BSS code added in the previous commits.

Subject: [PATCH 0939/1816] sata_promise: don't classify overruns as HSM errors
When sata_promise encounters an overrun or underrun error it
translates that to a libata AC_ERR_HSM, causing a hard reset.
Since over/under-runs were thought to be rare and transient,
this action seemed reasonable.
Unfortunately it turns out that the controller throws overrun
errors when e.g. hal polls a CD or DVD writer containing blank
media, causing long sequences of hard resets and retries before
EH finally gives up.
This patch updates sata_promise to classify over/under-runs as
AC_ERR_OTHER instead. This allows libata EH and upper layers to
retry or fail the operation as they see fit without the disruption
caused by repeated hard resets.
This fixes a problem using a DVD-RAM drive with sata_promise,
reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

Subject: [PATCH 0944/1816] drm/i915: Read the response after issuing DDC bus
switch command
For some SDVO cards based on conexant chip, we can't read the EDID if
we don't read the response after issuing SDVO DDC bus switch
command.
From the SDVO spec once when another I2C transaction is finished after
completing the I2C transaction of issuing the bus switch command, it
will be switched back to the SDVO internal state again. So we can't
initiate a new I2C transaction to read the response after issuing the
DDC bus switch command. Instead we should issue DDC bus switch command
and read the response in the same I2C transaction.

Subject: [PATCH 0945/1816] drm/i915: try another possible DDC bus for the SDVO
device with multiple outputs
There exist multiple DDC buses for the SDVO cards with multiple outputs.
When we can't get the EDID by using the select DDC bus, we can try the other
possible DDC bus to see whether the EDID can be obtained.

Subject: [PATCH 0946/1816] drm/i915: Don't wait interruptible for possible
plane buffer flush
When we setup buffer for display plane, we'll check any pending
required GPU flush and possible make interruptible wait for flush
complete. But that wait would be most possibly to fail in case of
signals received for X process, which will then fail modeset process
and put display engine in unconsistent state. The result could be
blank screen or CPU hang, and DDX driver would always turn on outputs
DPMS after whatever modeset fails or not.
So this one creates new helper for setup display plane buffer, and
when needing flush using uninterruptible wait for that.
This one should fix bug like https://bugs.freedesktop.org/show_bug.cgi?id=24009.
Also fixing mode switch stress test on Ironlake.

Fix compilation breakage of all m68knommu targets:
CC arch/m68knommu/kernel/asm-offsets.s
In file included from include/linux/sched.h:77,
from arch/m68knommu/kernel/asm-offsets.c:12:
include/linux/percpu.h: In function 'per_cpu_ptr_to_phys':
include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy
This is broken in linux-2.6.33-rc3.
Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.
A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().
Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.

Subject: [PATCH 0954/1816] lib: Introduce generic list_sort function
There are two copies of list_sort() in the tree already, one in the DRM
code, another in ubifs. Now XFS needs this as well. Create a generic
list_sort() function from the ubifs version and convert existing users
to it so we don't end up with yet another copy in the tree.

world writeable permissions
/sys/bus/pci/drivers/megaraid_sas/poll_mode_io defaults to being
world-writable, which seems bad (letting any user affect kernel driver
behavior).
This turns off group and user write permissions, so that on typical
production systems only root can write to it.

Subject: [PATCH 0959/1816] futexes: Remove rw parameter from get_futex_key()
Currently, futexes have two problem:
A) The current futex code doesn't handle private file mappings properly.
get_futex_key() uses PageAnon() to distinguish file and
anon, which can cause the following bad scenario:
1) thread-A call futex(private-mapping, FUTEX_WAIT), it
sleeps on file mapping object.
2) thread-B writes a variable and it makes it cow.
3) thread-B calls futex(private-mapping, FUTEX_WAKE), it
wakes up blocked thread on the anonymous page. (but it's nothing)
B) Current futex code doesn't handle zero page properly.
Read mode get_user_pages() can return zero page, but current
futex code doesn't handle it at all. Then, zero page makes
infinite loop internally.
The solution is to use write mode get_user_page() always for
page lookup. It prevents the lookup of both file page of private
mappings and zero page.
Performance concerns:
Probaly very little, because glibc always initialize variables
for futex before to call futex(). It means glibc users never see
the overhead of this patch.
Compatibility concerns:
This patch has few compatibility issues. After this patch,
FUTEX_WAIT require writable access to futex variables (read-only
mappings makes EFAULT). But practically it's not a problem,
glibc always initalizes variables for futexes explicitly - nobody
uses read-only mappings.

Subject: [PATCH 0960/1816] Input: pmouse - move Sentelic probe down the list
Sentelic probes confuse IBM trackpoints so they stop responding to
TP_READ_ID command. See:
http://bugzilla.kernel.org/show_bug.cgi?id=14970
Let's move FSP detection lower so it is probed after trackpoint and
others, just before we strat probing for Intellimouse Explorer.

Subject: [PATCH 0962/1816] perf: Stop stack frame walking off kernel addresses
boundaries
While processing kernel perf callchains, an bad entry can be
considered as a valid stack pointer but not as a kernel address.
In this case, we hang in an endless loop. This can happen in an
x86-32 kernel after processing the last entry in a kernel
stacktrace.
Just stop the stack frame walking after we encounter an invalid
kernel address.
This fixes a hard lockup in x86-32.

At least on Debian PARISC64, using:

Using built-in specs.
Target: hppa-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian

there are issues about using 'gcc -o /dev/null':
/usr/bin/ld: final link failed: File truncated
collect2: ld returned 1 exit status
So we test that and use /dev/null in environments where it
works, while using an .INTERMEDIATE file on those where it can't
be used, so that the .perf.dev.null file can be used instead and
then deleted when make exits.

This fixes the problem of the initialization code not correctly

the map_high() interface needed to be changed to accommodate

Subject: [PATCH 0967/1816] xen: fix hang on suspend.
In 65f63384 "xen: improve error handling in do_suspend" I said:
- xs_suspend()/xs_resume() and dpm_suspend_noirq()/dpm_resume_noirq() were not
nested in the obvious way.
and changed the ordering of the calls as so:
BEFORE AFTER
xs_suspend dpm_suspend_noirq
dpm_suspend_noirq xs_suspend
*SUSPEND* *SUSPEND*
dpm_resume_noirq dpm_resume_noirq
xs_resume xs_resume
Clearly this is not an improvement and I was talking rubbish.
In particular the new ordering is susceptible to a hang if a xenstore write is
in progress at the point at which the suspend kicks in. When the suspend
process calls xs_suspend it tries to take the request_mutex but if a write is
in progress it could be looping in xenbus_xs.c:read_reply() waiting for
something to arrive on &xs_state.reply_list while holding the request_mutex
(taken in the caller of read_reply).
However if we have done dpm_suspend_noirq before xs_suspend then we won't get
any more xenstore interrupts and process_msg() will never be woken up to add
anything to the reply_list.
Fix this by calling xs_suspend before dpm_suspend_noirq. If dpm_suspend_noirq
fails then make sure we go through the xs_suspend_cancel() code path.

Subject: [PATCH 0968/1816] x86/agp: Fix agp_amd64_init and agp_amd64_cleanup
This fixes the regression introduced by the commit
f405d2c02395a74d3883bd03ded36457aa3697ad.
The above commit fixes the following issue:
http://marc.info/?l=linux-kernel&m=126192729110083&w=2
However, it doesn't work properly when you remove and insert the
agp_amd64 module again.
agp_amd64_init() and agp_amd64_cleanup should be called only
when gart_iommu is not called earlier (that is, the GART IOMMU
is not enabled). We need to use 'gart_iommu_aperture' to see if
GART IOMMU is enabled or not.

Though I must admit I didn't find any *explicit* load of
%ss from this structure the better to be on a safe side
and set it to a known value.

Subject: [PATCH 0970/1816] x86: xen: 64-bit kernel RPL should be 0
Under Xen 64 bit guests actually run their kernel in ring 3,
however the hypervisor takes care of squashing descriptor the
RPLs transparently (in order to allow them to continue to
differentiate between user and kernel space CS using the RPL).
Therefore the Xen paravirt backend should use RPL==0 instead of
1 (or 3). Using RPL==1 causes generic arch code to take
incorrect code paths because it uses "testl $3, <CS>, je foo"
type tests for a userspace CS and this considers 1==userspace.
This issue was previously masked because get_kernel_rpl() was
omitted when setting CS in kernel_thread(). This was fixed when
kernel_thread() was unified with 32 bit in
f443ff4201dd25cd4dec183f9919ecba90c8edc2.

Subject: [PATCH 0974/1816] kbuild: really fix bzImage build with non-bash sh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh,
arch/x86/boot/compressed/vmlinux.bin.lzma ends with
'\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and
the resulting vmlinuz fails to boot. This improves on the
previous behavior, in which the file contained the characters
'-ne ' as well, but not by much.
Previous commits replaced "echo -ne" first with "/bin/echo -ne",
then "printf" in the hope of improving portability, but none of
these commands is guaranteed to support hexadecimal escapes on
POSIX systems. So use the shell to convert from hexadecimal to
octal.
With this change, an LZMA-compressed kernel built with dash as sh
boots correctly again.

Subject: [PATCH 0975/1816] Makefile: do not override LC_CTYPE
Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.
So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.

Subject: [PATCH 0976/1816] ALSA: hda - Fix Toshiba NB20x quirk entry
The alc664-mode4 model doesn't seem to fit with Toshiba NB205 correctly.
NB205 uses the pin 0x17 connected with the mixer 0x0f for the speaker
output, which isn't controlled by mode4 model at all.
Rather model=auto works fine as is on the latest driver, so let it back
again.

Subject: [PATCH 0980/1816] [S390] duplicate SIGTRAP on signal delivery.
The code in do_signal sets the TIF_SINGLE_STEP bit and calls
tracehook_signal_handler after the signal frame has been set up.
This causes two SIGTRAP signals to be delivered to the tracer.
Stop setting the TIF_SINGLE_STEP bit in do_signal to get the
correct number of SIGTRAPs.

Subject: [PATCH 0986/1816] [S390] use helpers for rlimits
Make sure compiler won't do weird things with limits. E.g. fetching
them twice may return 2 different values after writable limits are
implemented.
I.e. either use rlimit helpers added in
3e10e716abf3c71bdb5d86b8f507f9e72236c9cd
or ACCESS_ONCE if not applicable.

Subject: [PATCH 0987/1816] [S390] smp: setup smp_processor_id early
smp_processor_id() is supposed to work before setup_arch() gets called.
Before that smp_processor_id() may return just an arbitrary value that
is contained in the uninitialized boot lowcore.
So provide the arch function which will override the weak function in
init/main.c.

Subject: [PATCH 0998/1816] vfs: Fix vmtruncate() regression
If __block_prepare_write() was failed in block_write_begin(), the
allocated blocks can be outside of ->i_size.
But new truncate_pagecache() in vmtuncate() does nothing if new < old.
It means the above usage is not working anymore.
So, this patch fixes it by removing "new < old" check. It would need
more cleanup/change. But, now -rc and truncate working is in progress,
so, this tried to fix it minimum change.

Subject: [PATCH 0999/1816] zlib: Fix build of powerpc boot wrapper
Commit ac4c2a3bbe5db5fc570b1d0ee1e474db7cb22585 broke the build
of all powerpc boot wrappers.
It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.
We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.
It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).
This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.
This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

Subject: [PATCH 1000/1816] ixgbe: Do not attempt to perform interrupts in
netpoll when down
This patch resolves issues seen when running netconsole and rebooting via
reboot -f. The issue was due to the fact that we were attempting to
perform interrupt actions when the q_vectors and rings had already been
freed via the ixgbe_shutdown routines.

Subject: [PATCH 1002/1816] e1000e: MDIO slow mode should always be done for
82577
A previous 82577 workaround that set the MDIO access speed to slow mode for
every PHY register read/write when the cable is unplugged should instead
set the access mode to always be slow before any PHY register access.
Since the mode bit gets cleared when the PHY is reset, set the mode after
every PHY reset.

When the interface is down and we are using polled mode for MCDI
operations, we busy-wait for completion for approximately 1 jiffy
using udelay() and then back off to schedule(). But the completion
will not wake the task, since we are using polled mode! We must use
schedule_timeout_uninterruptible() instead.

Commit 87668d352aa8d135bd695a050f18bbfc7b50b506, titled "tg3: Don't
touch RCB nic addresses", tried to avoid assigning the nic address of
the standard producer ring. Unfortunately, the default nic address is
not correct for the 5787, the 5755M, or the 57765. This patch
reenables the old behavior and opts out of the assignment only
for the 5717.

Subject: [PATCH 1007/1816] tg3: Fix std rx prod ring handling
There are some tg3 devices that require the driver to post new rx
buffers in smaller increments. Commit
4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider
rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx
producer ring updates, but it does not make any special considerations
for the above-mentioned devices. For those devices, it is possible for
the driver to hit the special case path, which updates the hardware
mailbox register but skips updating the shadow software mailbox member.
If the special case path represents the final mailbox update for this
ISR iteration, the hardware and software mailbox values will be out of
sync. Ultimately, this will cause the driver to use a stale mailbox
value on the next iteration, which will appear to the hardware as a
large rx buffer update. Bad things ensue.
The fix is to update the software shadow mailbox member when the special
case path is taken.

2.6.33 ships. Since the kernel is already at RC3, serdes support
will require too many patches to fix. For these reasons, this patch
disables 5717 serdes support and will refuse to attach to all 5717
devices that are later than an A0 revision.

Subject: [PATCH 1011/1816] ipv6: skb_dst() can be NULL in ipv6_hop_jumbo().
This fixes CERT-FI FICORA #341748
Discovered by Olli Jarva and Tuomo Untinen from the CROSS
project at Codenomicon Ltd.
Just like in CVE-2007-4567, we can't rely upon skb_dst() being
non-NULL at this point. We fixed that in commit
e76b2b2567b83448c2ee85a896433b96150c92e6 ("[IPV6]: Do no rely on
skb->dst before it is assigned.")
However commit 483a47d2fe794328d29950fe00ce26dd405d9437 ("ipv6: added
net argument to IP6_INC_STATS_BH") put a new version of the same bug
into this function.
Complicating analysis further, this bug can only trigger when network
namespaces are enabled in the build. When namespaces are turned off,
the dev_net() does not evaluate it's argument, so the dereference
would not occur.
So, for a long time, namespaces couldn't be turned on unless SYSFS was
disabled. Therefore, this code has largely been disabled except by
people turning it on explicitly for namespace development.
With help from Eugene Teo <eugene@redhat.com>

available
Similar to 82571/2/3 parts that already do this, if ESB2/80003es2lan parts
have an alternate MAC address provided in the EEPROM use it instead of the
default MAC address. This patch makes the the actual code that does this
generic so that it can be better used by both MAC families.

Subject: [PATCH 1016/1816] e1000e: provide MAC-family-specific function to set
LAN ID
Provide MAC-specific function pointer to determine the LAN ID (PCI func).
The LAN ID is used internally by the driver to determine which h/w lock
to use to protect accessing the PHY on ESB2 as well as help to determine
the alternate MAC address on some parts.

Subject: [PATCH 1017/1816] e1000e: genericize the update multicast address
list
Make updating the multicast address list generic for all families and
enforce the requirement to update the entire multicast table array all at
once instead of piecemeal which causes problems on some parts.

Subject: [PATCH 1019/1816] qeth: avoid recovery during device online setting
If a qeth device is set online, several initialisation steps are
performed. If a failure in one of these steps occurs, the qeth
device is reset into DOWN state. If due to the failure a qeth recovery
is scheduled and started in another thread, this might cause all kinds
of conflicts, even a kernel panic. The patch forbids scheduling of a
qeth recovery while online processing is performed till the card is in
state SOFTSETUP.

Subject: [PATCH 1024/1816] proc_fops: convert drivers/isdn/ to seq_file
Convert code away from ->read_proc/->write_proc interfaces. Switch to
proc_create()/proc_create_data() which make addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.
Problem with ->read_proc et al is described here commit
786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in
/proc entries"

Subject: [PATCH 1026/1816] fix autofs/afs/etc. magic mountpoint breakage
We end up trying to kfree() nd.last.name on open("/mnt/tmp", O_CREAT)
if /mnt/tmp is an autofs direct mount. The reason is that nd.last_type
is bogus here; we want LAST_BIND for everything of that kind and we
get LAST_NORM left over from finding parent directory.
So make sure that it *is* set properly; set to LAST_BIND before
doing ->follow_link() - for normal symlinks it will be changed
by __vfs_follow_link() and everything else needs it set that way.

commit 5300990c0370e804e49d9a59d928c5d53fb73487 had stepped on a rather
nasty mess: definitions of ACC_MODE used to be different. Fixed the
resulting breakage, converting them to variant that takes O_... value;
all callers have that and it actually simplifies life (see tomoyo part
of changes).

Subject: [PATCH 1031/1816] ecryptfs: Fix refcnt leak on ecryptfs_follow_link()
error path
If ->follow_link handler return the error, it should decrement
nd->path refcnt. But, ecryptfs_follow_link() doesn't decrement.
This patch fix it by using usual nd_set_link() style error handling,
instead of playing with nd->path.

Subject: [PATCH 1032/1816] Fix the -ESTALE handling in do_filp_open()
Instead of playing sick games with path saving, cleanups, just retry
the entire thing once with LOOKUP_REVAL added. Post-.34 we'll convert
all -ESTALE handling in there to that style, rather than playing with
many retry loops deep in the call chain.

Ah, you are right. I took '%' for '&'. John, would you revert it? Sorry
for the false alarm.

Subject: [PATCH 1039/1816] cfg80211: fix channel setting for wext
Patch fixes the bug at
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2139
Currently we cannot set the channel using wext extension
if we have already associated and disconnected. As
cfg80211_mgd_wext_siwfreq will not switch the channel if ssid is set.
This fixes it by clearing the ssid.
Following is the sequence which it tries to fix.
modprobe iwlagn
iwconfig wlan0 essid ""
ifconfig wlan0 down
iwconfig wlan0 chan X
wext is marked as deprecate.If we use nl80211 we can easily play with
setting the channel.

Subject: [PATCH 1041/1816] cfg80211: fix 2 GHz subband calculation for country
IEs
Country IEs triplets are getting an extra channel with
the current count. This does not affect regulatory because
we always took the intersection between what the AP gave
and what CRDA believed is correct.
This however does fix processing some Country IEs with multiple
sequential 2 GHz triplets. Since our parser and the spec mandates
all channels be monitonically increasing we would drop the IE after
noticing the second triplet begins on a channel already processed.
APs that send these type of country IEs seems rare though.

Subject: [PATCH 1044/1816] Remove config option B43_LEGACY_RFKILL completely
In f41f3f373dd72344c65d801d6381fe83ef3a2c54 the B43 driver was ported
to use the cfg80211 API for rfkill and consequently the config option
was dropped (RFKILL is now unconditionally enabled).
However in the Kernel Info the feature is still checked and reported
missing. This patch just removes the conditional and the relevant code
blocks while still reporting that feature unconditionally would be
another option (it's always there).

Subject: [PATCH 1047/1816] mac80211: improve powersave documentation
There has been some confusion how drivers should implement powersave
support. Improve the documentation a bit to make it more clear what
drivers need to do. Also mention about U-APSD.

we would end up treating these IEs as single channel units. These are in

wireless-testing commit 7044cc56
In wireless-testing, commit 7044cc56 added struct ieee80211_hdr_3addr
to include/linux/ieee80211.h. This definition collides with one that is
in the r8187se driver in staging.
The conflict is resolved by changing r8187se to use the definition from
include/linuc/ieee80211.h.

Subject: [PATCH 1053/1816] powerpc/8xx: Always pin kernel instruction TLB
Various kernel asm modifies SRR0/SRR1 just before executing
a rfi. If such code crosses a page boundary you risk a TLB miss
which will clobber SRR0/SRR1. Avoid this by always pinning
kernel instruction TLB space.

Subject: [PATCH 1057/1816] powerpc: cpumask_of_node() should handle -1 as a
node
pcibus_to_node can return -1 if we cannot determine which node a pci bus
is on. If passed -1, cpumask_of_node will negatively index the lookup array
and pull in random data:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
00000000,00000003,00000000,00000000
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist
64-65
Change cpumask_of_node to check for -1 and return cpu_all_mask in this
case:
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
ffffffff,ffffffff,ffffffff,ffffffff
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist

It seems that in qemu, we can see an interrupt in R3 despite the
fact that it's masked in W1. The chip doesn't actually issue an
interrupt, but we can "see" it when taking an interrupt for the
other channel. This may be a qemu bug ... or not, so let's be
safe and avoid calling into the UART layer when that happens which
woulc cause a crash.

Subject: [PATCH 1063/1816] powerpc: Fix decrementer setup on 1GHz boards
We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX
boards anymore. As it seems, patch 8d165db1 [powerpc: Improve
decrementer accuracy] introduced this problem. The routine div_sc()
overflows with shift = 32 resulting in this incorrect setup:
time_init: decrementer frequency = 1000.000012 MHz
time_init: processor frequency = 1000.000012 MHz
clocksource: timebase mult[400000] shift[22] registered
clockevent: decrementer mult[33] shift[32] cpu[0]
This patch now introduces a local div_dc64() version of this function
so that this overflow doesn't happen anymore.

Subject: [PATCH 1064/1816] powerpc/8xx: Fix user space TLB walk in dcbX fixup
The newly added fixup for buggy dcbX insn's has
a bug that always trigger a kernel TLB walk so a user space
dcbX insn will cause a Kernel Machine Check if it hits DTLB error.

It looks like the previous patch sent out to move RTAS and
other items from /proc/ppc64 to /proc/powerpc missed a few
files needed for RAS and DLPAR functionality.
Original Patch here:
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-September/076096.html
This patch updates the remaining files to be created under /proc/powerpc.

Subject: [PATCH 1075/1816] ARM: MINI2440: Fixup __initdata usage
Remove some of the __initdata tags which are currently inappropriate for
platform_device and some of the platform data. These can be returned once
support for copying platform devices and data is added.

Subject: [PATCH 1076/1816] net/core/sock.c: quiet sparse noise
In sock_getsockopt the symbol 'lv' is declared as an
unsigned int type, probably due to sizeof returning a
size_t which is really an unsigned int.
This produces a sparse warning for SO_PEERNAME due to
the sock->ops->getname() call:
warning: incorrect type in argument 3 (different signedness)
expected int *sockaddr_len
got unsigned int *<noident>
Quiet the warning by changing the type of 'lv' to an int.

Subject: [PATCH 1077/1816] ipv4: Use less conflicting local var name in
change_nexthops() loop macro.
As noticed by H Hartley Sweeten, since change_nexthops() uses 'nh'
as it's iterator variable, it can conflict with other existing
local vars.
Use "nexthop_nh" to avoid the conflict and make it easier to figure
out where this magic variable comes from.

Subject: [PATCH 1083/1816] dccp_probe: Fix module load dependencies between
dccp and dccp_probe
This was just recently reported to me. When built as modules, the
dccp_probe module has a silent dependency on the dccp module. This
stems from the fact that the module_init routine of dccp_probe
registers a jprobe on the dccp_sendmsg symbol. Since the symbol is
only referenced as a text string (the .symbol_name field in the jprobe
struct) rather than the address of the symbol itself, depmod never
picks this dependency up, and so if you load the dccp_probe module
without the dccp module loaded, the register_jprobe call fails with an
-EINVAL, and the whole module load fails.
The fix is pretty easy, we can just wrap the register_jprobe call in a
try_then_request_module call, which forces the dependency to get
satisfied prior to the probe registration.

Subject: [PATCH 1084/1816] tun: export underlying socket
Tun device looks similar to a packet socket
in that both pass complete frames from/to userspace.
This patch fills in enough fields in the socket underlying tun driver
to support sendmsg/recvmsg operations, and message flags
MSG_TRUNC and MSG_DONTWAIT, and exports access to this socket
to modules. Regular read/write behaviour is unchanged.
This way, code using raw sockets to inject packets
into a physical device, can support injecting
packets into host network stack almost without modification.
First user of this interface will be vhost virtualization
accelerator.

Subject: [PATCH 1086/1816] vhost_net: a kernel-level virtio server
What it is: vhost net is a character device that can be used to reduce
the number of system calls involved in virtio networking.
Existing virtio net code is used in the guest without modification.
There's similarity with vringfd, with some differences and reduced scope
- uses eventfd for signalling
- structures can be moved around in memory at any time (good for
migration, bug work-arounds in userspace)
- write logging is supported (good for migration)
- support memory table and not just an offset (needed for kvm)
common virtio related code has been put in a separate file vhost.c and
can be made into a separate module if/when more backends appear. I used
Rusty's lguest.c as the source for developing this part : this supplied
me with witty comments I wouldn't be able to write myself.
What it is not: vhost net is not a bus, and not a generic new system
call. No assumptions are made on how guest performs hypercalls.
Userspace hypervisors are supported as well as kvm.
How it works: Basically, we connect virtio frontend (configured by
userspace) to a backend. The backend could be a network device, or a tap
device. Backend is also configured by userspace, including vlan/mac
etc.
Status: This works for me, and I haven't see any crashes.
Compared to userspace, people reported improved latency (as I save up to
4 system calls per packet), as well as better bandwidth and CPU
utilization.
Features that I plan to look at in the future:
- mergeable buffers
- zero copy
- scalability tuning: figure out the best threading model to use
Note on RCU usage (this is also documented in vhost.h, near
private_pointer which is the value protected by this variant of RCU):
what is happening is that the rcu_dereference() is being used in a
workqueue item. The role of rcu_read_lock() is taken on by the start of
execution of the workqueue item, of rcu_read_unlock() by the end of
execution of the workqueue item, and of synchronize_rcu() by
flush_workqueue()/flush_work(). In the future we might need to apply
some gcc attribute or sparse annotation to the function passed to
INIT_WORK(). Paul's ack below is for this RCU usage.

Subject: [PATCH 1092/1816] ALSA: hda - Fix mute led GPIO on HP dv-series
notebooks
On my laptop (HP dv6-1110ax), there are no OEM strings in SMBIOS of type
"HP_Mute_LED*". Hence, the GPIO for the mute button LED doesn't get set
properly. I didn't find the strings in my cousin's laptop (HP dv9500t CTO)
either.
As per the documentation of find_mute_led_gpio(), these strings occur
in HP B-series systems - so, before scanning the SMBIOS strings, we need to
check if we're dealing with a B-series system.
Need to get confirmation from HP if this logic takes care of all the
systems. I'm trying to poke a friend there.

Subject: [PATCH 1095/1816] drm/i915: remove loop in Ironlake interrupt handler
On Ironlake, there is an interrupt master control bit. With the bit
disabled before clearing IIR, we do not need to handle extra interrupt
in a loop. This patch removes the loop in Ironlake interrupt handler.
It fixed irq lost issue on some Ironlake platforms.

Subject: [PATCH 1097/1816] xfs: Avoid inodes in reclaim when flushing from
inode cache
The reclaim code will handle flushing of dirty inodes before reclaim
occurs, so avoid them when determining whether an inode is a
candidate for flushing to disk when walking the radix trees. This
is based on a test patch from Christoph Hellwig.

Subject: [PATCH 1098/1816] xfs: reclaim all inodes by background tree walks
We cannot do direct inode reclaim without taking the flush lock to
ensure that we do not reclaim an inode under IO. We check the inode
is clean before doing direct reclaim, but this is not good enough
because the inode flush code marks the inode clean once it has
copied the in-core dirty state to the backing buffer.
It is the flush lock that determines whether the inode is still
under IO, even though it is marked clean, and the inode is still
required at IO completion so we can't reclaim it even though it is
clean in core. Hence the requirement that we need to take the flush
lock even on clean inodes because this guarantees that the inode
writeback IO has completed and it is safe to reclaim the inode.
With delayed write inode flushing, we coul dend up waiting a long
time on the flush lock even for a clean inode. The background
reclaim already handles this efficiently, so avoid all the problems
by killing the direct reclaim path altogether.

Subject: [PATCH 1101/1816] xfs: fix missing error check in xfs_rtfree_range
When xfs_rtfind_forw() returns an error, the block is returned
uninitialised. xfs_rtfree_range() is not checking the error return,
so could be using an uninitialised block number for modifying bitmap
summary info.
The problem was found by gcc when compiling the *userspace* libxfs
code - it is an copy of the kernel code with the exact same bug.
gcc gives an uninitialised variable warning on the userspace code
but not on the kernel code. You gotta love the consistency (Mmmm,
slightly chewy today!).

Subject: [PATCH 1102/1816] xfs: xfs_swap_extents needs to handle dynamic fork
offsets
When swapping extents, we can corrupt inodes by swapping data forks
that are in incompatible formats. This is caused by the two indoes
having different fork offsets due to the presence of an attribute
fork on an attr2 filesystem. xfs_fsr tries to be smart about
setting the fork offset, but the trick it plays only works on attr1
(old fixed format attribute fork) filesystems.
Changing the way xfs_fsr sets up the attribute fork will prevent
this situation from ever occurring, so in the kernel code we can get
by with a preventative fix - check that the data fork in the
defragmented inode is in a format valid for the inode it is being
swapped into. This will lead to files that will silently and
potentially repeatedly fail defragmentation, so issue a warning to
the log when this particular failure occurs to let us know that
xfs_fsr needs updating/fixing.
To help identify how to improve xfs_fsr to avoid this issue, add
trace points for the inodes being swapped so that we can determine
why the swap was rejected and to confirm that the code is making the
right decisions and modifications when swapping forks.
A further complication is even when the swap is allowed to proceed
when the fork offset is different between the two inodes then value
for the maximum number of extents the data fork can hold can be
wrong. Make sure these are also set correctly after the swap occurs.

Subject: [PATCH 1105/1816] mac80211: Fixed netif_tx_wake_all_queues in IBSS
mode
When ieee80211_offchannel_return is called, it needs to re-enabled TX
queues that have been stopped in ieee80211_offchannel_stop_beaconing or
ieee80211_offchannel_stop_station. It happens if we are doing a scan with an
IBSS interface. In this case, the interface stopped transmitting.

Subject: [PATCH 1106/1816] cfg80211: make regulatory_hint_11d() band specific
In practice APs do not send country IE channel triplets for channels
the AP is not operating on and if they were to do so they would have
to use the regulatory extension which we currently do not process.
No AP has been seen in practice that does this though so just drop
those country IEs.
Additionally it has been noted the first series of country IE
channels triplets are specific to the band the AP sends. Propagate
the band on which the country IE was found on reject the country
IE then if the triplets are ever oustide of the band.
Although we now won't process country IE information with multiple
band information we leave the intersection work as is as it is
technically possible for someone to want to eventually process these
type of country IEs with regulatory extensions.

Subject: [PATCH 1107/1816] mac80211: force use_short_slot=true for 5GHz
Normally 5GHz does not have a concept of long vs short slot time,
however the slot time that it ends up using is the same as for 2.4 GHZ
and use_short_slot == true
Because of that, it makes more sense to force use_short_slot = true
whenever 5 GHz is being used, so that this particular check does not
have to be in every single driver that uses this flag.

Subject: [PATCH 1109/1816] ath9k: cleanup slot time and ack/cts timeout
handling
Previously ath9k left the initialization of slot timing and ACK/CTS
timeout to the mode specific initvals. This does not handle short vs
long slot in 2.4 GHz and uses a rather strange value for the 2.4 GHz
ACK timeout (64 usec).
This patch uses the proper ath9k_hw functions for setting slot time and
timeouts and also implements the switch between short and long slot
time in 2.4 GHz

Subject: [PATCH 1119/1816] b43: N-PHY: update init code to match current specs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previous init path was based on old specs from old driver. Update it
as much as possible leaving some TODOs for not implemented functions.

Subject: [PATCH 1144/1816] drm/i915: disable LVDS downclock by default
Many platform support this feature, and it can provide significant
power savings when the reduced refresh rate is low. However, on some
platforms a secondary (reduced) timing is provided but not actually
supported by the hardware. This results in undesirable flicker at
runtime.
So disable the feature by default, but allow users to opt-in to the
reduced clock behavior with a new module parameter, lvds_downclock,
that can be set to 1 to enable the feature.

Subject: [PATCH 1146/1816] drm/i915: fix pixel color depth setting on eDP
Original DP mode_valid check didn't take pixel color depth into account,
which made one 1600x900 eDP panel's mode check invalid because of overclock,
but actually this 6bpc panel does can work with x1 lane at 2.7G. This one
trys to take bpp value properly both in mode validation and mode setting.

Subject: [PATCH 1148/1816] inotify: do not reuse watch descriptors
Since commit 7e790dd5fc937bc8d2400c30a05e32a9e9eef276 ("inotify: fix
error paths in inotify_update_watch") inotify changed the manor in which
it gave watch descriptors back to userspace. Previous to this commit
inotify acted like the following:
inotify_add_watch(X, Y, Z) = 1
inotify_rm_watch(X, 1);
inotify_add_watch(X, Y, Z) = 2
but after this patch inotify would return watch descriptors like so:
inotify_add_watch(X, Y, Z) = 1
inotify_rm_watch(X, 1);
inotify_add_watch(X, Y, Z) = 1
which I saw as equivalent to opening an fd where
open(file) = 1;
close(1);
open(file) = 1;
seemed perfectly reasonable. The issue is that quite a bit of userspace
apparently relies on the behavior in which watch descriptors will not be
quickly reused. KDE relies on it, I know some selinux packages rely on
it, and I have heard complaints from other random sources such as debian
bug 558981.
Although the man page implies what we do is ok, we broke userspace so
this patch almost reverts us to the old behavior. It is still slightly
racey and I have patches that would fix that, but they are rather large
and this will fix it for all real world cases. The race is as follows:
- task1 creates a watch and blocks in idr_new_watch() before it updates
the hint.
- task2 creates a watch and updates the hint.
- task1 updates the hint with it's older wd
- task removes the watch created by task2
- task adds a new watch and will reuse the wd originally given to task2
it requires moving some locking around the hint (last_wd) but this should
solve it for the real world and be -stable safe.
As a side effect this patch papers over a bug in the lib/idr code which
is causing a large number WARN's to pop on people's system and many
reports in kerneloops.org. I'm working on the root cause of that idr
bug seperately but this should make inotify immune to that issue.

Subject: [PATCH 1155/1816] ACPI: don't cond_resched if irq is disabled
commit 8bd108d adds preemption point after each opcode parse, then
a sleeping function called from invalid context bug was founded
during suspend/resume stage. this was fixed in commit abe1dfa by
don't cond_resched when irq_disabled. But recent commit 138d156 changes
the behaviour to don't cond_resched when in_atomic. This makes the
sleeping function called from invalid context bug happen again, which
is reported in http://lkml.org/lkml/2009/12/1/371.
This patch also fixes http://bugzilla.kernel.org/show_bug.cgi?id=14483

Subject: [PATCH 1156/1816] eeepc-laptop: disable cpu speed control on EeePC
701
The EeePC 4G ("701") implements CFVS, but it is not supported by the
pre-installed OS, and the original option to change it in the BIOS
setup screen was removed in later versions. Judging by the lack of
"Super Hybrid Engine" on Asus product pages, this applies to all "701"
models (4G/4G Surf/2G Surf).
So Asus made a deliberate decision not to support it on this model.
We have several reports that using it can cause the system to hang [1].
That said, it does not happen all the time. Some users do not
experience it at all (and apparently wish to continue "right-clocking").
Check for the EeePC 701 using DMI. If met, then disable writes to the
"cpufv" sysfs attribute and log an explanatory message.
Add a "cpufv_disabled" attribute which allow users to override this
policy. Writing to this attribute will log a second message.
The sysfs attribute is more useful than a module option, because it
makes it easier for userspace scripts to provide consistent behaviour
(according to user configuration), regardless of whether the kernel
includes this change.

Some new models need to disable wireless hotplug.
For the moment, we don't know excactly what models need that,
except 1005HA.
Users will be able to use that param as a workaround.

Subject: [PATCH 1161/1816] ACPI: Fix section mismatch error for
acpi_early_processor_set_pdc()
Alex Chiang introduced acpi_early_processor_set_pdc() in commit:
ACPI: processor: call _PDC early
78f1699659963fff97975df44db6d5dbe7218e55
But this results in a section mismatch:
WARNING: drivers/acpi/acpi.o(.text+0xa9c1): Section mismatch in reference from the
function acpi_early_processor_set_pdc() to the variable .cpuinit.data:processor_idle_dmi_table
The function acpi_early_processor_set_pdc() references
the variable __cpuinitdata processor_idle_dmi_table.
This is often because acpi_early_processor_set_pdc lacks a __cpuinitdata
annotation or the annotation of processor_idle_dmi_table is wrong.
The only caller of acpi_early_processor_set_pdc() is acpi_bus_init() which
is an "__init" function. So the correct fix here is to mark
acpi_early_processor_set_pdc() "__init" too.

Subject: [PATCH 1163/1816] qlge: Add basic firmware dump.
Adding the infrstructure and basic data for the firmware
core dump.
The firmware coredump is turned OFF by default. There will be no
memory allocations for data dumps to the log.

MNT_WRITE_HOLD shouldn't leak into new vfsmount and neither

Subject: [PATCH 1188/1816] markup_oops.pl: fix error with x86
When I try to use markup_oops.pl in x86, I always get:
cat 1 | perl markup_oops.pl ./vmlinux
objdump: --start-address: bad number: NaN
No matching code found
This is because in line:
if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}
$func_offset will get a number like "0x2"
But in follow code:
my $decodestart = Math::BigInt->from_hex("0x$target") -
Math::BigInt->from_hex("0x$func_offset");
It add other ox to ox2. Then this value will be set to NaN.
So I made a small patch to fix it.

Subject: [PATCH 1190/1816] m68knommu: fix invalid flags on coldfire pit
clocksource
The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource. Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.
This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource. This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).

Subject: [PATCH 1191/1816] edac: i5000_edac critical fix panic out of bounds
EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4)
Kernel panic - not syncing: EDAC MC0: Uncorrected Error (XEN) Domain 0 crashed: 'noreboot' set - not rebooting.
This happens because FERR_NF_FBD bit 28 is not updated on i5000. Due to
that, both bits 28 and 29 may be equal to one, returning channel = 3. As
this value is invalid, EDAC core generates the panic.

Subject: [PATCH 1194/1816] kfifo: sanitize *_user error handling
Right now for kfifo_*_user it's not easily possible to distingush between
a user copy failing and the FIFO not containing enough data. The problem
is that both conditions are multiplexed into the same return code.
Avoid this by moving the "copy length" into a separate output parameter
and only return 0/-EFAULT in the main return value.
I didn't fully adapt the weird "record" variants, those seem
to be unused anyways and were rather messy (should they be just removed?)
I would appreciate some double checking if I did all the conversions
correctly.

Subject: [PATCH 1196/1816] kfifo: add kfifo_initialized
Simple inline that checks if kfifo_init() has been executed on a fifo.
This is useful for walking all per CPU fifos, when some of them might not
have been brought up yet.

power of two
On my first try using them I missed that the fifos need to be power of
two, resulting in a runtime bug. Document that requirement everywhere
(and fix one grammar bug)

The current check for 'backward merging' within add_active_range() does
not seem correct. start_pfn must be compared against
early_node_map[i].start_pfn (and NOT against .end_pfn) to find out whether
the new region is backward-mergeable with the existing range.

Subject: [PATCH 1199/1816] kernel.h: add BUILD_BUG_ON_NOT_POWER_OF_2()
Add BUILD_BUG_ON_NOT_POWER_OF_2()
When code relies on a constant being a power of 2:
#define FOO 512 /* must be a power of 2 */
it would be nice to be able to do:
BUILD_BUG_ON(!is_power_of_2(FOO));
However applying an inline function does not result in a compile-time
constant that can be used with BUILD_BUG_ON(), so trying that gives
results in:
error: bit-field '<anonymous>' width not an integer constant
As suggested by akpm, rather than monkeying around with is_power_of_2()
and risking gcc warts about constant expressions, just create a macro
BUILD_BUG_ON_NOT_POWER_OF_2() to encapsulate this common requirement.

running on a single-CPU system. If all zones are unreclaimble,
sleeping_prematurely return 1 and kswapd will call balance_pgdat() again.
but it's totally meaningless, balance_pgdat() doesn't anything against

Subject: [PATCH 1203/1816] memcg: ensure list is empty at rmdir
Current mem_cgroup_force_empty() only ensures mem->res.usage == 0 on
success. But this doesn't guarantee memcg's LRU is really empty, because
there are some cases in which !PageCgrupUsed pages exist on memcg's LRU.
For example:
- Pages can be uncharged by its owner process while they are on LRU.
- race between mem_cgroup_add_lru_list() and __mem_cgroup_uncharge_common().
So there can be a case in which the usage is zero but some of the LRUs are not empty.
OTOH, mem_cgroup_del_lru_list(), which can be called asynchronously with
rmdir, accesses the mem_cgroup, so this access can cause a problem if it
races with rmdir because the mem_cgroup might have been freed by rmdir.
Actually, I saw a bug which seems to be caused by this race.

[1530745.950651] Fixing recursive fault but reboot is needed!
The problem here is pages on LRU may contain pointer to stale memcg. To
make res->usage to be 0, all pages on memcg must be uncharged or moved to
another(parent) memcg. Moved page_cgroup have already removed from
original LRU, but uncharged page_cgroup contains pointer to memcg withou
PCG_USED bit. (This asynchronous LRU work is for improving performance.)
If PCG_USED bit is not set, page_cgroup will never be added to memcg's
LRU. So, about pages not on LRU, they never access stale pointer. Then,
what we have to take care of is page_cgroup _on_ LRU list. This patch
fixes this problem by making mem_cgroup_force_empty() visit all LRUs
before exiting its loop and guarantee there are no pages on its LRU.

Subject: [PATCH 1205/1816] sysdev: fix prototype for memory_sysdev_class
show/store functions
The function prototype mismatches in call stack:
[<ffffffff81494268>] print_block_size+0x58/0x60
[<ffffffff81487e3f>] sysdev_class_show+0x1f/0x30
[<ffffffff811d629b>] sysfs_read_file+0xcb/0x1f0
[<ffffffff81176328>] vfs_read+0xc8/0x180
Due to prototype mismatch, print_block_size() will sprintf() into
*attribute instead of *buf, hence user space will read the initial
zeros from *buf:
$ hexdump /sys/devices/system/memory/block_size_bytes
0000000 0000 0000 0000 0000
0000008
After patch:
cat /sys/devices/system/memory/block_size_bytes
0x8000000
This complements commits c29af9636 and 4a0b2b4dbe.

Subject: [PATCH 1206/1816] nommu: fix SYSV SHM for NOMMU
Commit c4caa778157dbbf04116f0ac2111e389b5cd7a29 ("file
->get_unmapped_area() shouldn't duplicate work of get_unmapped_area()")
broke SYSV SHM for NOMMU by taking away the pointer to
shm_get_unmapped_area() from shm_file_operations.
Put it back conditionally on CONFIG_MMU=n.
file->f_ops->get_unmapped_area() is used to find out the base address for a
mapping of a mappable chardev device or mappable memory-based file (such as a
ramfs file). It needs to be called prior to file->f_ops->mmap() being called.

Subject: [PATCH 1208/1816] nommu: remove a superfluous check of
vm_region::vm_usage
In split_vma(), there's no need to check if the VMA being split has a
region that's in use by more than one VMA because:
(1) The preceding test prohibits splitting of non-anonymous VMAs and regions
(eg: file or chardev backed VMAs).
(2) Anonymous regions can't be mapped multiple times because there's no handle
by which to refer to the already existing region.
(3) If a VMA has previously been split, then the region backing it has also
been split into two regions, each of usage 1.

Subject: [PATCH 1210/1816] nommu: fix race between ramfs truncation and shared
mmap
Fix the race between the truncation of a ramfs file and an attempt to make
a shared mmap of region of that file.
The problem is that do_mmap_pgoff() calls f_op->get_unmapped_area() to
verify that the file region is made of contiguous pages and to find its
base address - but there isn't any locking to guarantee this region until
vma_prio_tree_insert() is called by add_vma_to_mm().
Note that moving the functionality into f_op->mmap() doesn't help as that
is also called before vma_prio_tree_insert().
Instead make ramfs_nommu_check_mappings() grab nommu_region_sem whilst it
does its checks. This means that this function will wait whilst mmaps
take place.

Subject: [PATCH 1211/1816] nommu: fix shared mmap after truncate shrinkage
problems
Fix a problem in NOMMU mmap with ramfs whereby a shared mmap can happen
over the end of a truncation. The problem is that
ramfs_nommu_check_mappings() checks that the reduced file size against the
VMA tree, but not the vm_region tree.
The following sequence of events can cause the problem:
fd = open("/tmp/x", O_RDWR|O_TRUNC|O_CREAT, 0600);
ftruncate(fd, 32 * 1024);
a = mmap(NULL, 32 * 1024, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
b = mmap(NULL, 16 * 1024, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
munmap(a, 32 * 1024);
ftruncate(fd, 16 * 1024);
c = mmap(NULL, 32 * 1024, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
Mapping 'a' creates a vm_region covering 32KB of the file. Mapping 'b'
sees that the vm_region from 'a' is covering the region it wants and so
shares it, pinning it in memory.
Mapping 'a' then goes away and the file is truncated to the end of VMA
'b'. However, the region allocated by 'a' is still in effect, and has
_not_ been reduced.
Mapping 'c' is then created, and because there's a vm_region covering the
desired region, get_unmapped_area() is _not_ called to repeat the check,
and the mapping is granted, even though the pages from the latter half of
the mapping have been discarded.
However:
d = mmap(NULL, 16 * 1024, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
Mapping 'd' should work, and should end up sharing the region allocated by
'a'.
To deal with this, we shrink the vm_region struct during the truncation,
lest do_mmap_pgoff() take it as licence to share the full region
automatically without calling the get_unmapped_area() file op again.

Subject: [PATCH 1212/1816] revert "drivers/video/s3c-fb.c: fix clock setting
for Samsung SoC Framebuffer"
Fix divide by zero and broken output. Commit 600ce1a0fa ("fix clock
setting for Samsung SoC Framebuffer") introduced a mandatory refresh
parameter to the platform data for the S3C framebuffer but did not
introduce any validation code, causing existing platforms (none of which
have refresh set) to divide by zero whenever the framebuffer is
configured, generating warnings and unusable output.
Ben Dooks noted several problems with the patch:
- The platform data supplies the pixclk directly and should already
have taken care of the refresh rate.
- The addition of a window ID parameter doesn't help since only the
root framebuffer can control the pixclk.
- pixclk is specified in picoseconds (rather than Hz) as the patch
assumed.
and suggests reverting the commit so do that. Without fixing this no
mainline user of the driver will produce output.

Subject: [PATCH 1218/1816] hw-breakpoints, perf: Fix broken mmiotrace due to
dr6 by reference change
Commit 62edab9056a6cf0c9207339c8892c923a5217e45 (from June 2009
but merged in 2.6.33) changes notify_die to pass dr6 by
reference.
However, it forgets to fix the check for DR_STEP in kmmio.c,
breaking mmiotrace. It also passes a wrong value to the post
handler.
This simple fix makes mmiotrace work again.

Subject: [PATCH 1219/1816] ALSA: hda - Fix capture on Sony VAIO with single
input
Sony VAIO VGN-P11G with ALC262 codec has only one input pin, and the
recording doesn't work with model=auto because ALC262 parser sets the
wrong cap NIDs to choose the route and the default route for the sole
input pin wasn't initialized properly. This patch solves these issues.

Subject: [PATCH 1224/1816] V4L/DVB (13831): uvcvideo: Fix oops caused by a
race condition in buffer dequeuing
Buffers were marked as done before being removed from the IRQ queue. If
a userspace application dequeued and requeued the buffer fast enough
during that time window, the buffer could end up being deleted twice,
generating an oops in interrupt context.
Add a new state, UVC_BUF_STATE_READY, to mark buffers as ready for reuse
but not yet removed from the queue, and transition to UVC_BUF_STATE_DONE
only when the buffer is removed from the queue.

Subject: [PATCH 1227/1816] feature-removal-schedule: Add v4l1 drivers
obsoleted by gspca sub drivers
This patch adds the ov511, quickcam_messenger, w9968cf, stv680 and ovcamchip
v4l1 drivers to the feature removal schedule as the devices they support
are now all also supported by v4l2 gspca sub drivers.
This patch also adds the v4l2 vc0301 driver for removal as it duplicates
functionality of the gspca_zc3xx driver, zc0301 only supports 2 USB-ID's
(because it only supports a limited set of sensors) wich are also
supported
by the gspca_zc3xx driver (which supports 53 USB-ID's in total).

The Quickcam Web camera would not produce an image if you removed and inserted the module multiple times without physically power cycling the camera first.
By writing zero to bridge register STV_SCAN_RATE (0x1443) the camera works as intended, regardless of the number of module insertions.

Subject: [PATCH 1236/1816] V4L/DVB mx1_camera: don't check platform_get_irq's
return value against zero
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use (int)irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

Remove the following compiler warning: 'dummy' is used uninitialized in this function.
Although the result in the dummy variable is not used the program flow in
soc_camera_limit_side() depends on the value in dummy. The program flow is better
to be deterministic.

Replaces Hans Verkuil by Andy Walls as the ivtv maintainer.
After 4 1/2 years, Hans decided to hand over the ivtv driver to Andy.
Andy was already doing more work on ivtv than him, so this just makes
official what was happening in practice.

Subject: [PATCH 1260/1816] V4L/DVB (13716): [Mantis] Bug: incorrect byte swap
You know, the worst endianness errors are not the cases where
people forget to byte-swap, but the cases where they either byte-swap
with the wrong size, or byte-swap when they shouldn't have done so at
all. Those ones defeat the casual reader of the code.

Subject: [PATCH 1361/1816] modpost: fix segfault in sym_is() with prefixed
arches
The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes. It does this first by searching the real symbol with the normal
unprefixed symbol. But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for. On non-prefixed arches, this is effectively the same thing,
so there is no problem. On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways. But every
once in a blue moon, you get the right page alignment and it segfaults.
For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name". The substring will thus return
one byte into "symbol" and store it into "match". But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage. i.e. the code ends up doing:
char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';

Btrfs: fix missing last-entry in readdir(3)
When one does a 32-bit readdir(3), the last entry of a directory is
missing. This is however not due to passing a large value to filldir,
but it seems to have to do with glibc doing telldir or something
quirky. In any case, this patch fixes it in practice.

Subject: [PATCH 1366/1816] Btrfs: fix regression in orphan cleanup
Currently orphan cleanup only ever gets triggered if we cross subvolumes during
a lookup, which means that if we just mount a plain jane fs that has orphans in
it, they will never get cleaned up. This results in panic's like these
http://www.kerneloops.org/oops.php?number=1109085
where adding an orphan entry results in -EEXIST being returned and we panic. In
order to fix this, we check to see on lookup if our root has had the orphan
cleanup done, and if not go ahead and do it. This is easily reproduceable by
running this testcase
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <string.h>
#include <unistd.h>
#include <stdio.h>
int main(int argc, char **argv)
{
char data[4096];
char newdata[4096];
int fd1, fd2;
memset(data, 'a', 4096);
memset(newdata, 'b', 4096);
while (1) {
int i;
fd1 = creat("file1", 0666);
if (fd1 < 0)
break;
for (i = 0; i < 512; i++)
write(fd1, data, 4096);
fsync(fd1);
close(fd1);
fd2 = creat("file2", 0666);
if (fd2 < 0)
break;
ftruncate(fd2, 4096 * 512);
for (i = 0; i < 512; i++)
write(fd2, newdata, 4096);
close(fd2);
i = rename("file2", "file1");
unlink("file1");
}
return 0;
}
and then pulling the power on the box, and then trying to run that test again
when the box comes back up. I've tested this locally and it fixes the problem.
Thanks to Tomas Carnecky for helping me track this down initially.

Subject: [PATCH 1367/1816] Btrfs: deal with NULL acl sent to btrfs_set_acl
It is legal for btrfs_set_acl to be sent a NULL acl. This
makes sure we don't dereference it. A similar patch was sent by

Subject: [PATCH 1368/1816] Btrfs: fix possible panic on unmount
We can race with the unmount of an fs and the stopping of a kthread where we
will free the block group before we're done using it. The reason for this is
because we do not hold a reference on the block group while its caching, since
the allocator drops its reference once it exits or moves on to the next block
group. This patch fixes the problem by taking a reference to the block group
before we start caching and dropping it when we're done to make sure all
accesses to the block group are safe. Thanks,

Subject: [PATCH 1369/1816] tcp: account SYN-ACK timeouts & retransmissions
Currently we don't increment SYN-ACK timeouts & retransmissions
although we do increment the same stats for SYN. We seem to have lost
the SYN-ACK accounting with the introduction of tcp_syn_recv_timer
(commit 2248761e in the netdev-vger-cvs tree).
This patch fixes this issue. In the process we also rename the v4/v6
syn/ack retransmit functions for clarity. We also add a new
request_socket operations (syn_ack_timeout) so we can keep code in
inet_connection_sock.c protocol agnostic.

__net_init/__net_exit are apparently not going away, so use them
to full extent.
In some cases __net_init was removed, because it was called from
__net_exit code.

Subject: [PATCH 1371/1816] bnx2: Refine statistics code.
Refine the statistics macros by passing in just the name of the
counter field. This makes it a lot easier and cleaner to add
counters saved before the last reset in the next patch.

Subject: [PATCH 1372/1816] bnx2: Save statistics during reset.
MTU changes, ring size changes, etc cause the chip to be reset and the
statisctics flushed. To keep track of the accumulated statistics, we
add code to save the whole statistics block before reset. We also
modify the macros and statistics functions to return the sum of the
saved and current counters.
Based on original patch by Breno Leitao <leitao@linux.vnet.ibm.com>

Subject: [PATCH 1381/1816] ARM: 5882/1: ARM: Fix uncompress code compile for
different defines of flush(void)
Because of the include of the decompress_inflate.c file from
boot/compress/misc.c, there are different flush() defines:
In file included from arch/arm/boot/compressed/misc.c:249:
arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
Fix this by removing the define of flush() in misc.c for
CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
and that is being included unconditionally.
Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug
for those platforms.

Subject: [PATCH 1382/1816] ALSA: Remove warning message for invalid OSS minor
ranges
When a card instance with a higher card number is registered, warning
messages are spewed eventually with stack traces due to the invalid minor
number for OSS device registration. For example, thinkpad-acpi registers
the card number 29 as default, and you'll see always these messages.
This is rather confusing (and worries users), thus better to return
simply the error code.

This reverts commit 14f0aa359365e8a93a77b71e3b840274b9b4dcb1.
That commit was needed earlier because system call restarting for
OABI (compat) required an executable stack and thus had problems
with NX. Since ab72b00734ae4d0b ("ARM: Fix signal restart issues
with NX and OABI compat") has reworked the code to not require an
executable stack anymore, we can re-enable NX support for kernels
with OABI (compat) support.

Using RTS/CTS will better protect the inner exchange from interference,

Subject: [PATCH 1391/1816] mac80211: fix sign error in pid controller
While testing the pid rate controller in mac80211_hwsim, I noticed
that once the controller reached 54 Mbit rates, it would fail to
lower the rate when necessary. The debug log shows:
1945 186786 pf_sample 50 3534 3577 50
My interpretation is that the fixed point scaling of the target
error value (pf) is incorrect: the error value of 50 compared to
a target of 14 case should result in a scaling value of
(14-50) = -36 * 256 or -9216, but instead it is (14 * 256)-50, or
3534.
Correct this by doing fixed point scaling after subtraction.

Subject: [PATCH 1392/1816] p54pci: rx frame length check
A long time ago, a user reported several crashes due to
data corruptions which are likely the result of a
not-100%-supported, or faulty? PCI bridge.
( http://patchwork.kernel.org/patch/53004/ )
This patch fixes entry #1.
"1. p54p_check_rx_ring - skb_over_panic: Under a ping flood
or just left running for a bit would panic with a skb_over_panic."
As described in the mail: The invalid frame length causes
skb_put to bailout and trigger a crash.
Note:
Simply dropping the frame is problematic, because if its content
contains a tx feedback we would lose some portion of the device
memory space.... And the driver/mac80211 should handle all other
invalid data.

Subject: [PATCH 1395/1816] x86, apic: use physical mode for IBM summit
platforms
Chris McDermott from IBM confirmed that hurricane chipset in IBM summit
platforms doesn't support logical flat mode. Irrespective of the other
things like apic_id's, total number of logical cpu's, Linux kernel
should default to physical mode for this system.
The 32-bit kernel does so using the OEM checks for the IBM summit
platform. Add a similar OEM platform check for the 64bit kernel too.
Otherwise the linux kernel boot can hang on this platform under certain
bios/platform settings.

logical cpus
We can use logical flat mode if there are <= 8 logical cpu's
(irrespective of physical apic id values). This will enable simplified
and efficient IPI and device interrupt routing on such platforms.
This has been tested to work on both Intel and AMD platforms.
Exceptions like IBM summit platform which can't use logical flat mode
are addressed by using OEM platform checks.

Subject: [PATCH 1398/1816] sh64: wire up sys_accept4.
sh64 on the other hand provides both direct broken out syscalls as well
as socketcall access. As there are binaries that use both socketcall has
to stay around. The current ABI prefers direct syscalls.
It was pointed out that when sys_recvmmsg was added in, sys_accept4 was
overlooked. This takes care of wiring it up.

Subject: [PATCH 1399/1816] dccp: fix dccp rmmod when kernel configured to use
slub
Hey all-
I was tinkering with dccp recently and noticed that I BUG halted the
kernel when I rmmod-ed the dccp module. The bug halt occured because the page
that I passed to kfree failed the PageCompound and PageSlab test in the slub
implementation of kfree. I tracked the problem down to the following set of
events:
1) dccp, unlike all other uses of kmem_cache_create, allocates a string
dynamically when registering a slab cache. This allocated string is freed when
the cache is destroyed.
2) Normally, (1) is not an issue, but when Slub is in use, it is possible that
caches are 'merged'. This process causes multiple caches of simmilar
configuration to use the same cache data structure. When this happens, the new
name of the cache is effectively dropped.
3) (2) results in kmem_cache_name returning an ambigous value (i.e.
ccid_kmem_cache_destroy, which uses this fuction to retrieve the name pointer
for freeing), is no longer guaranteed that the string it assigned is what is
returned.
4) If such merge event occurs, ccid_kmem_cache_destroy frees the wrong pointer,
which trips over the BUG in the slub implementation of kfree (since its likely
not a slab allocation, but rather a pointer into the static string table
section.
So, what to do about this. At first blush this is pretty clearly a leak in the
information that slub owns, and as such a slub bug. Unfortunately, theres no
really good way to fix it, without exposing slub specific implementation details
to the generic slab interface. Also, even if we could fix this in slub cleanly,
I think the RCU free option would force us to do lots of string duplication, not
only in slub, but in every slab allocator. As such, I'd like to propose this
solution. Basically, I just move the storage for the kmem cache name to the
ccid_operations structure. In so doing, we don't have to do the kstrdup or
kfree when we allocate/free the various caches for dccp, and so we avoid the
problem, by storing names with static memory, rather than heap, the way all
other calls to kmem_cache_create do.
I've tested this out myself here, and it solves the problem quite well.

Subject: [PATCH 1400/1816] phylib: Move workqueue initialization to a proper
place
commit 541cd3ee00a4fe975b22fac6a3bc846bacef37f7 ("phylib: Fix deadlock
on resume") caused TI DaVinci EMAC ethernet driver to oops upon resume:
PM: resume of devices complete after 237.098 msecs
Restarting tasks ... done.
kernel BUG at kernel/workqueue.c:354!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
[...]
Backtrace:
[<c002c598>] (__bug+0x0/0x2c) from [<c0052a54>] (queue_delayed_work_on+0x74/0xf8)
[<c00529e0>] (queue_delayed_work_on+0x0/0xf8) from [<c0052b30>] (queue_delayed_work+0x2c/0x30)
The oops pops up because TI DaVinci EMAC driver detaches PHY on
suspend and attaches it back on resume. Attaching makes phylib call
phy_start_machine() that initializes a workqueue. On the other hand,
PHY's resume routine will call phy_start_machine() again, and that
will cause the oops since we just destroyed the already scheduled
workqueue.
This patch fixes the issue by moving workqueue initialization to
phy_device_create().
p.s. We don't see this oops with ucc_geth and gianfar drivers because
they perform a fine-grained suspend, i.e. they just stop the PHYs
without detaching.

Subject: [PATCH 1401/1816] ucc_geth: Fix full TX queue processing
commit 7583605b6d29f1f7f6fc505b883328089f3485ad ("ucc_geth: Fix empty
TX queue processing") fixed empty TX queue mishandling, but didn't
account another corner case: when TX queue becomes full.
Without this patch the driver will stop transmiting when TX queue
becomes full since 'bd == ugeth->txBd[txQ]' actually checks for
two things: queue empty or full.
Let's better check for NULL skb, which unambiguously signals an empty
queue.

9c705260feea6ae329bc6b6d5f6d2ef0227eda0a
I was just looking at ppp_generic, and noticed that it fairly recently
(as in the last year) got rather mangled with many spaces turned into tabs
in places they very much shouldn't have been. I tracked it down to commit
9c705260feea6ae329bc6b6d5f6d2ef0227eda0a (ppp: ppp_mp_explode() redesign).
I am amazed if that patch passed the patch checking script. I have no
idea what kind of weird editor setting did this, but it has to have been a
weird editor setting or a very unfortunate search and replace gone wrong.
I only found it trying to apply a patch I was playing with and wondering
why it wouldn't apply. Then I found there were tabs in the middle of
comments that used to be spaces.
Well here is a patch that should fix it up as far as I can tell.
Purely whitespace repair. No actual code changes.

Subject: [PATCH 1405/1816] ipv4: allow warming up the ARP cache with request
type gratuitous ARP
If the per device ARP_ACCEPT option is enable, currently we only allow
creating new ARP cache entries for response type gratuitous ARP.
Allowing gratuitous ARP to create new ARP entries (not only to update
existing ones) is useful when we want to avoid unnecessary delays for
the first packet of a stream.
This patch allows request type gratuitous ARP to create new ARP cache
entries as well. This is useful when we want to populate the ARP cache
entries for a large number of hosts on the same LAN.

For more information on the v7 DCC, see Cortex-A8 TRM
"12.11.1 Debug communications channel".
To use it with post 2.6.33-rc1 or later, you need to have:
CONFIG_DEBUG_LL=y
ONFIG_DEBUG_ICEDCC=y
CONFIG_EARLY_PRINTK=y
Earlier kernels need commit 93fd03a8c6728b58879f8af20ffd55d9c32a778b

Subject: [PATCH 1410/1816] ARM: 5886/1: arm: Fix cpu_proc_fin() for proc-v7.S
and make kexec work
The comments in arm_machine_restart() suggest that cpu_proc_fin()
will clean and disable cache and turn off interrupts. This does
not seem to be implemented for proc-v7.S, implement it the same
way as for proc-v6.S.
This also makes kexec work for v7. Note that a related TLB and
branch traget flush patch is also needed to avoid kexec
"crc error".
Note that there are still some issues that seem to be related
to L2 cache being on and causing occasional uncompress "crc error"
with kexec. Anyways, this gets kexec mostly working on V7 for now.

Subject: [PATCH 1415/1816] iwlwifi: add num_of_sos_stats to statistics counter
When uCode detects number of beacon missed consecutively above the
internal missed beacon threshold (set by uCode), it will reset and
re-tune the radio in order to get out of bad PHY state.
This "num_of_sos_states" counter monitors number of time uCode
encounters this bad condition and has to re-tune the radio.

This does not mean frames are lost - their processing is just delayed until

Subject: [PATCH 1420/1816] iwlwifi: remove extra statistics request from
debugfs
When reading current ucode statistics information from debugfs, in
current implementation, it will always send a new "statistics request" to
uCode. In normal operation, uCode should report the statistics per beacon
interval. Remove this extra request to reduce the additional command exchanges
between driver and uCode.

Subject: [PATCH 1425/1816] mac80211: remove useless setting of
IEEE80211_TX_INTFL_DONT_ENCRYPT
There's no value in setting a flag that will
never be checked after this point, this seems
to be legacy code -- I think previously the
flag was used to check whether to encrypt the
frame or not. Now, however, the flag need not
be set, and setting it actually interferes if
the frame will be processed again later.

Subject: [PATCH 1426/1816] mac80211: move control.hw_key assignment
When mac80211 asks a driver to encrypt a frame, it
must assign the control.hw_key pointer for it to
know which key to use etc. Currently, mac80211 does
this whenever it would software-encrypt a frame.
Change the logic of this code to assign the hw_key
pointer when selecting the key, and later check it
when deciding whether to encrypt the frame or let
it be encrypted by the hardware. This allows us to
later simply skip the encryption function since it
no longer modifies the TX control.

Subject: [PATCH 1427/1816] mac80211: re-enable re-transmission of filtered
frames
In an earlier commit,
mac80211: disable software retry for now
Pavel Roskin reported a problem that seems to be due to
software retry of already transmitted frames. It turns
out that we've never done that correctly, but due to
some recent changes it now crashes in the TX code. I've
added a comment in the patch that explains the problem
better and also points to possible solutions -- which
I can't implement right now.
I disabled software retry of failed/filtered frames
because it was broken. With the work of the previous
patches, it now becomes fairly easy to re-enable it
by adding a flag indicating that the frame shouldn't
be modified, but still running it through the transmit
handlers to populate the control information.

Subject: [PATCH 1435/1816] cfg80211: rcu-ify rdev and wdev
Future code will need to look up rdev and wdev
within atomic sections, but currently we need
to lock a mutex for such lookups. Change the
list handling for both to be RCU-safe so that
we can look them up in rcu sections instead in
the future.

Subject: [PATCH 1436/1816] ath9k: fix RTS/CTS handling
The Tx DMA descriptor has two kinds of flags that select RTS/CTS usage.
The first one (global for the frame) selects whether RTS/CTS or
CTS-to-self should be used, the second one enables RTS/CTS or
CTS-to-self usage for an individual multi-rate-retry entry.
Previously the code preparing the descriptor only enabled the global
flag, if the first MRR series selected the local one.
Fix this by enabling the global flag if any of the MRR entries need it.
With this patch, rate control can properly select the use of RTS/CTS
for all MRR entries except the first one, which is the default behavior.

Subject: [PATCH 1440/1816] p54pci: move tx cleanup into tasklet
This patch moves the tx cleanup routines out of the critical
interrupt context and into the (previously known as rx) tasklet.
The main goal of this operation is to remove the extensive
usage of spin_lock_irqsaves in the generic p54common library.
The next step would be to modify p54usb to do the
rx processing inside a tasklet (just like usbnet).

Subject: [PATCH 1447/1816] libertas: Set/clear WPA keys before the WEP ones
With the v10 firmware running on 8688 HW, clearing WPA keys after setting the
WEP key prevents us from being able to associate with WEP APs.
Swapping the calling order for assoc_helper_wpa_keys() and
assoc_helper_wep_keys fixes that issue.

Subject: [PATCH 1448/1816] nl80211: Allow association to change channels
during reassociation
nl80211_associate() was rejecting (re)association attempts with EBUSY
in some cases where we are currently associated with an AP that uses
different channel from the destination AP. Fix this by passing the
current wdev to rdev_fixed_channel() in the same way that was already
done for join-IBSS and connect commands. This allows the fixedchan
check to skipped for the current wdev and allows the reassociation to
proceed.

Subject: [PATCH 1449/1816] ath9k: make tx power config changes take effect
immediatley
Users wishing to tweak tx power want it to happen immediately,
try to respect that. This was tested by Lorenzo by measuring the
received signal strength from an AP with ath9k and the patch.
Changing the tx power on the AP produced these results:
1) iwconfig wlan0 txpower 20 ---> Rx power -37dbm
2) iwconfig wlan0 txpower 15 ---> Rx power -41dbm
3) iwconfig wlan0 txpower 10 ---> Rx power -45dbm
4) iwconfig wlan0 txpower 5 ---> Rx power -51dbm
5) iwconfig wlan0 txpower 0 ---> Rx power -37dbm
The result with 0 is an anomoly and would need to be
addressed through a separate patch.

When cleaning up beacon buffers and slots, ath9k currently checks if
sc->ah->opmode is set to a beacon related mode before cleaning up
buffers.
An unfortunate ordering of interface up/down commands can lead to
sc->ah->opmode being set to monitor mode, while there are AP interfaces
present on the same wiphy.
Always cleaning up beacon buffers if present fixes this issue.

Subject: [PATCH 1455/1816] eCryptfs: Use notify_change for truncating lower
inodes
When truncating inodes in the lower filesystem, eCryptfs directly
invoked vmtruncate(). As Christoph Hellwig pointed out, vmtruncate() is
a filesystem helper function, but filesystems may need to do more than
just a call to vmtruncate().
This patch moves the lower inode truncation out of ecryptfs_truncate()
and renames the function to truncate_upper(). truncate_upper() updates
an iattr for the lower inode to indicate if the lower inode needs to be
truncated upon return. ecryptfs_setattr() then calls notify_change(),
using the updated iattr for the lower inode, to complete the truncation.
For eCryptfs functions needing to truncate, ecryptfs_truncate() is
reintroduced as a simple way to truncate the upper inode to a specified
size and then truncate the lower inode accordingly.

Subject: [PATCH 1456/1816] eCryptfs: Add getattr function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The i_blocks field of an eCryptfs inode cannot be trusted, but
generic_fillattr() uses it to instantiate the blocks field of a stat()
syscall when a filesystem doesn't implement its own getattr(). Users
have noticed that the output of du is incorrect on newly created files.
This patch creates ecryptfs_getattr() which calls into the lower
filesystem's getattr() so that eCryptfs can use its kstat.blocks value
after calling generic_fillattr(). It is important to note that the
block count includes the eCryptfs metadata stored in the beginning of
the lower file plus any padding used to fill an extent before
encryption.

Subject: [PATCH 1457/1816] eCryptfs: Remove mmap from directory operations
Adrian reported that mkfontscale didn't work inside of eCryptfs mounts.
Strace revealed the following:
open("./", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
fcntl64(3, F_GETFD) = 0x1 (flags FD_CLOEXEC)
open("./fonts.scale", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
getdents(3, /* 80 entries */, 32768) = 2304
open("./.", O_RDONLY) = 5
fcntl64(5, F_SETFD, FD_CLOEXEC) = 0
fstat64(5, {st_mode=S_IFDIR|0755, st_size=16384, ...}) = 0
mmap2(NULL, 16384, PROT_READ, MAP_PRIVATE, 5, 0) = 0xb7fcf000
close(5) = 0
--- SIGBUS (Bus error) @ 0 (0) ---
+++ killed by SIGBUS +++
The mmap2() on a directory was successful, resulting in a SIGBUS
signal later. This patch removes mmap() from the list of possible
ecryptfs_dir_fops so that mmap() isn't possible on eCryptfs directory
files.

Subject: [PATCH 1458/1816] ecryptfs: initialize private persistent file before
dereferencing pointer
Ecryptfs_open dereferences a pointer to the private lower file (the one
stored in the ecryptfs inode), without checking if the pointer is NULL.
Right afterward, it initializes that pointer if it is NULL. Swap order of
statements to first initialize. Bug discovered by Duckjin Kang.

But the only user of ecryptfs_interpose to pass a non-zero flag to it, has
hard-coded the value as "1". This could spell trouble if any of these values

Subject: [PATCH 1465/1816] ACPI: processor: restrict early _PDC to opt-in
platforms
Commit 78f1699 (ACPI: processor: call _PDC early) blindly walks
the namespace and calls _PDC on every processor object it finds.
This change may cause issues on platforms that declare dummy
values for SSDTs on non-present processors (disabled in MADT).
When we call _PDC and dynamically attempt to execute the AML
Load() op on these dummy SSDTs, there's no telling what might
happen.
Rather than finding every platform that has bogus SSDTs, restrict
early _PDC calls to platforms that are known to need early
evaluation of _PDC.
This is a minimal, temporary fix (given the context of the
current release cycle). A real solution of checking the MADT for
non-present processors will be written for the next merge window.

Subject: [PATCH 1467/1816] ACPI: enable C2 and Turbo-mode on Nehalem notebooks
on A/C
Linux has always ignored ACPI BIOS C2 with exit latency > 100 usec,
and the ACPI spec is clear that is correct FADT-supplied C2.
However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.
So move the 100usec C2 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.
This bug has not been visible until Nehalem, which advertises
a CPU-C2 worst case exit latency on servers of 205usec.
That (incorrect) figure is being used by BIOS writers
on mobile Nehalem systems for the AC configuration.
Thus, Linux ignores C2 leaving just C1, which is
saves less power, and also impacts performance
by preventing the use of turbo mode.

Subject: [PATCH 1468/1816] ACPI: allow C3 > 1000usec
Do for C3 what the previous patch did for C2.
The C2 patch was in response to a highly visible
and multiply reported C-state/turbo failure,
while this change has no bug report in-hand.
This will enable C3 in Linux on systems where BIOS
overstates C3 latency in _CST. It will also enable
future systems which may actually have C3 > 1000usec.
Linux has always ignored ACPI BIOS C3 with exit latency > 1000 usec,
and the ACPI spec is clear that is correct FADT-supplied C3.
However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.
So move the 1000usec C3 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.

Subject: [PATCH 1472/1816] libata: retry FS IOs even if it has failed with
AC_ERR_INVALID
libata currently doesn't retry if a command fails with AC_ERR_INVALID
assuming that retrying won't get it any further even if retried.
However, a failure may be classified as invalid through hardware
glitch (incorrect reading of the error register or firmware bug) and
there isn't whole lot to gain by not retrying as actually invalid
commands will be failed immediately. Also, commands serving FS IOs
are extremely unlikely to be invalid. Retry FS IOs even if it's
marked invalid.
Transient and incorrect invalid failure was seen while debugging
firmware related issue on Samsung n130 on bko#14314.

There is nothing arch specific to devtmpfs. This part crashes because the
kernel tries to modify the data read-only section which is write protected
on s390.

Subject: [PATCH 1475/1816] compat_ioctl: Supress "unknown cmd" message on
serial /dev/console
After the commit fb07a5f8 ("compat_ioctl: remove all VT ioctl
handling"), I got this error message on 64-bit mips kernel with 32-bit
busybox userland:
ioctl32(init:1): Unknown cmd fd(0) cmd(00005600){t:'V';sz:0} arg(7fd76480) on /dev/console
The cmd 5600 is VT_OPENQRY. The busybox's init issues this ioctl to
know vt-console or serial-console. If the console was serial console,
VT ioctls are not handled by the serial driver.
And by quick search, I found some programs using VT_GETMODE to check
vt-console is available or not.

Nozomi goes wrong if you get the sequence

close
which turns out to occur on some ppp type setups.
This is a quick patch up for the problem. It's not really fixing Nozomi
which completely fails to implement tty open/close semantics and all the
other needed stuff. Doing it right is a rather more invasive patch set and
not one that will backport.

Subject: [PATCH 1478/1816] serial-core: resume serial hardware with
no_console_suspend
Perform a tricky suspend/resume even with no_console_suspend.
With no_console_suspend, kernel skips serial port suspend/resume and the
serial hardware may remain in undefined state after resume. It actually
happens on devices that don't have BIOS that handle serial
initialization. It makes impossible to use serial console after resume.
Devices affected by this problem include:
Sharp Zaurus devices
Several PXA based ARM embedded boards
The patch does:
- Save the hardware state
- Perform buffer flush in time of its suspend call
- Tell the driver that port is suspended
- But still accept new data
- And keep console hardware in state that allows to send them
It allows to capture late console messages without breaking console
after resume.
This is just a resend of a patch discussed in these threads, as the
patch was not yet applied.

patch which fixes an Oops in by asus_oled module on 2.6.32.2 kernel,
caused by incorrect usage of strict_strtoul function call within
set_enabled and set_disabled functions. This can be triggered by simple
running the userspace client for asus_old (e.g., 'asusoled -e' or

et131x: Fix 12bit wrapping
From: Alan Cox <alan@linux.intel.com>
The 12bit wrap logic conversion is wrong and this shows up for some
memory sizes and layouts of card. Patch it up for now, once the kernel
view of status is cleaned up it'll become two variables and a lot saner.

Therefore GFP_KERNEL cannot be safely used between usb_lock_device()

Subject: [PATCH 1490/1816] USB: EHCI: fix handling of unusual interrupt
intervals
This patch (as1320) fixes two problems related to interrupt-URB
scheduling in ehci-hcd.
URBs with an interval of 2 or 4 microframes aren't handled.
For the time being, the patch reduces to interval to 1 uframe.
URBs are constrained to have an interval no larger than 1024
frames by usb_submit_urb(). But some EHCI controllers allow
use of a schedule as short as 256 frames; for these
controllers we may have to decrease the interval to the
actual schedule length.
The second problem isn't very significant since few devices expose
interrupt endpoints with an interval larger than 256 frames. But the
first problem is critical; it will prevent the kernel from working
with devices having interrupt intervals of 2 or 4 uframes.

Subject: [PATCH 1491/1816] USB: EHCI & UHCI: fix race between root-hub suspend
and port resume
This patch (as1321) fixes a problem with EHCI and UHCI root-hub
suspends: If the suspend occurs while a port is trying to resume, the
resume doesn't finish and simply gets lost. When remote wakeup is
enabled, this is undesirable behavior.
The patch checks first to see if any port resumes are in progress, and
if they are then it fails the root-hub suspend with -EBUSY.

Subject: [PATCH 1492/1816] USB: add missing delay during remote wakeup
This patch (as1330) fixes a bug in khbud's handling of remote
wakeups. When a device sends a remote-wakeup request, the parent hub
(or the host controller driver, for directly attached devices) begins
the resume sequence and notifies khubd when the sequence finishes. At
this point the port's SUSPEND feature is automatically turned off.
However the device needs an additional 10-ms resume-recovery time
(TRSMRCY in the USB spec). Khubd does not wait for this delay if the
SUSPEND feature is off, and as a result some devices fail to behave
properly following a remote wakeup. This patch adds the missing
delay to the remote-wakeup path.
It also extends the resume-signalling delay used by ehci-hcd and
uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use
for non-remote-wakeup resumes). The extra time appears to help some
devices.

[ 427.916699] Call Trace:
The problem is caused by a mismatch between the USB core's view of the
device state and the USB device and xHCI host's view of the device state.
After the device reset and re-configuration, the device and the xHCI host
think they are using alternate setting 0 of all interfaces. However, the
USB core keeps track of the old state, which may include non-zero
alternate settings. It uses intf->cur_altsetting to keep the endpoint
sysfs files for the old state across the reset.
The bandwidth allocation functions need to know what the xHCI host thinks
the current alternate settings are, so original patch set
intf->cur_altsetting to the alternate setting 0. This caused duplicate
endpoint files to be created.
The solution is to not set intf->cur_altsetting before calling
usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a
new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use
alternate setting 0 as the currently installed alternate setting.

Subject: [PATCH 1497/1816] USB: fix usbstorage for 2770:915d delivers no FAT
Resolves kernel.org bug 14914.
Remove entry for 2770:915d (usb digital camera with mass storage
support) from unusual_devs.h. The fix triggered by the entry causes
the file system on the camera to be completely inaccessible (no
partition table, the device is not mountable).
The patch works, but let me clarify a few things about it. All the
patch does is remove the entry for this device from the
drivers/usb/storage/unusual_devs.h, which is supposed to help with a
problem with the device's reported size (I think). I'm pretty sure it
was originally added for a reason, so I'm not sure removing it won't
cause other problems to reappear. Also, I should note that this
unusual_devs.h entry was present (and activating workarounds) in
2.6.29, but in that version everything works fine. Starting with
2.6.30, things no longer work.

Subject: [PATCH 1498/1816] USB: isp1362: better 64bit printf warning fixes
Some hosts that treat the return value of sizeof differently from unsigned
long might still hit warnings. So use %zu for sizeof() values. This is a
better version of the previous commit b0a9cf297e58721933.

Subject: [PATCH 1499/1816] USB: isp1362: fix build failure on ARM systems via
irq_flags cleanup
There was some left over #ifdef ARM logic that is outdated but no one
really noticed. So instead of relying on this tricky logic, properly
load and utilize the platform irq_flags resources.

Subject: [PATCH 1501/1816] e1000: enhance frame fragment detection
Originally From: Neil Horman <nhorman@tuxdriver.com>
Modified by: Jesse Brandeburg <jesse.brandeburg@intel.com>
Hey all-
A security discussion was recently given:
http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html
And a patch that I submitted awhile back was brought up. Apparently some of
their testing revealed that they were able to force a buffer fragment in e1000
in which the trailing fragment was greater than 4 bytes. As a result the
fragment check I introduced failed to detect the fragement and a partial
invalid frame was passed up into the network stack. I've written this patch
to correct it. I'm in the process of testing it now, but it makes good
logical sense to me. Effectively it maintains a per-adapter state variable
which detects a non-EOP frame, and discards it and subsequent non-EOP frames
leading up to _and_ _including_ the next positive-EOP frame (as it is by
definition the last fragment). This should prevent any and all partial frames
from entering the network stack from e1000.

very hard to craft a packet that could abuse this, it is possible.

Subject: [PATCH 1506/1816] tg3: Abort phy init for 5717 serdes devices
The 5717 serdes devices have a different phy register layout than all
other previous serdes devices. This patch aborts the phy init sequence
in tg3_phy_reset() if the device is a 5717 serdes. It also aborts the
tg3_phy_toggle_apd() operation. Most other operations in the MII_SERDES
path are O.K.

Subject: [PATCH 1520/1816] sched: Fix vmark regression on big machines
SD_PREFER_SIBLING is set at the CPU domain level if power saving isn't
enabled, leading to many cache misses on large machines as we traverse
looking for an idle shared cache to wake to. Change the enabler of
select_idle_sibling() to SD_SHARE_PKG_RESOURCES, and enable same at the
sibling domain level.

reacquire_kernel_lock() fail
Assume A->B schedule is processing, if B have acquired BKL before and it
need reschedule this time. Then on B's context, it will go to
need_resched_nonpreemptible for reschedule. But at this time, prev and
switch_count are related to A. It's wrong and will lead to incorrect

Paul questioned the context in which we should call

called from IRQ context these days, however the fallback call-site is
placed in softirq context. Ammend this by placing the callback in the IRQ
timer path.

Subject: [PATCH 1526/1816] vmalloc: remove BUG_ON due to racy counting of
VM_LAZY_FREE
In free_unmap_area_noflush(), va->flags is marked as VM_LAZY_FREE first, and
then vmap_lazy_nr is increased atomically.
But, in __purge_vmap_area_lazy(), while traversing of vmap_are_list, nr
is counted by checking VM_LAZY_FREE is set to va->flags. After counting
the variable nr, kernel reads vmap_lazy_nr atomically and checks a
BUG_ON condition whether nr is greater than vmap_lazy_nr to prevent
vmap_lazy_nr from being negative.
The problem is that, if interrupted right after marking VM_LAZY_FREE,
increment of vmap_lazy_nr can be delayed. Consequently, BUG_ON
condition can be met because nr is counted more than vmap_lazy_nr.
It is highly probable when vmalloc/vfree are called frequently. This
scenario have been verified by adding delay between marking VM_LAZY_FREE
and increasing vmap_lazy_nr in free_unmap_area_noflush().
Even the vmap_lazy_nr is for checking high watermark, it never be the
strict watermark. Although the BUG_ON condition is to prevent
vmap_lazy_nr from being negative, vmap_lazy_nr is signed variable. So,
it could go down to negative value temporarily.
Consequently, removing the BUG_ON condition is proper.
A possible BUG_ON message is like the below.

Subject: [PATCH 1531/1816] be2net: fix bug in rx page posting
Pages are posted to the rxq in such a way that more than one frag
can share the page. The last frag that uses the page unmaps the
page. In the case when a page is not fully used (due to lack of space in rxq)
the last frag that uses the page is not being set as a "last_page_user";
instead, the next frag in the rxq is incorrectly being set.
The fix has also been tested on ppc64 with 64k pages...

use that to store their own data. We also need to pass
the virtual interface pointer.

Subject: [PATCH 1534/1816] cfg80211: export multiple MAC addresses in sysfs
If a device has multiple MAC addresses, userspace will
need to know about that. Similarly, if it allows the
MAC addresses to vary by a bitmask.
If a driver exports multiple addresses, it is assumed
that it will be able to deal with that many different
addresses, which need not necessarily match the ones
programmed into the device; if a mask is set then the
device should deal addresses within that mask based
on an arbitrary "base address".
To test it all and show how it is used, add support
to hwsim even though it can't actually deal with
addresses different from the default.

Subject: [PATCH 1535/1816] mac80211: Account HT Control field in Data frame
hdrlen according to 802.11n-2009
ieee80211_hdrlen() should account account new HT Control field in 802.11
data frame header introduced by IEEE 802.11n standard.
According to 802.11n-2009 HT Control field is present in data frames
when both of following are met:
1. It is QoS data frame.
2. Order bit is set in Frame Control field.
The change might be totally compatible with legacy non-11n aware frames,
because 802.11-2007 standard states that "all QoS STAs set this subfield
to 0".

Subject: [PATCH 1536/1816] ath5k: dont use external sleep clock in AP mode
When using the external sleep clock in AP mode, the
TSF increments too quickly, causing beacon interval
to be much lower than it is supposed to be, resulting
in lots of beacon-not-ready interrupts.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14802.

Subject: [PATCH 1537/1816] ath5k: fix setup for CAB queue
The beacon sent gating doesn't seem to work with any combination
of flags. Thus, buffered frames tend to stay buffered forever,
using up tx descriptors.
Instead, use the DBA gating and hold transmission of the buffered
frames until 80% of the beacon interval has elapsed using the ready
time. This fixes the following error in AP mode:
ath5k phy0: no further txbuf available, dropping packet
Add a comment to acknowledge that this isn't the best solution.

Subject: [PATCH 1539/1816] mac80211: fix rx data handling for non-data frames
on multiple vifs
The loop that passes non-data frames to all relevant vifs inside the
__ieee80211_rx_handle_packet keeps a pointer to the previous sdata to
avoid having to make unnecessary copies of the frame it's handling.
This led to a bug that caused it to apply the ieee80211_rx_data state
to the wrong interface, thereby either missing the rx.sta pointer or
having it assigned where it shouldn't be.
This breaks (among other things) aggregation on some vifs, as action
frame exchages are dropped to the cooked monitor interface due to
rx->sta being NULL.
Fix this by restructuring the loop so that it prepares the rx data just
before making the skb copy and calling the rx handlers.

Subject: [PATCH 1550/1816] e1000/e1000e: don't use small hardware rx buffers
When testing the "e1000: enhance frame fragment detection" (and e1000e)
patches we found some bugs with reducing the MTU size. The 1024 byte
descriptor used with the 1000 mtu test also (re) introduced the
(originally) reported bug, and causes us to need the e1000_clean_tx_irq
"enhance frame fragment detection" fix.
So what has occured here is that 2.6.32 is only vulnerable for mtu <
1500 due to the jumbo specific routines in both e1000 and e1000e.
So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but
is not vulnerable to the original issue reported. It has been pointed
out that this vulnerability needs to be patched in older kernels that
don't have the e1000 jumbo routine. Without the jumbo routines, we
need the "enhance frame fragment detection" fix the e1000, old
e1000e is only vulnerable for < 1500 mtu, and needs a similar
fix. We split the patches up to provide easy backport paths.
There is only a slight bit of extra code when this fix and the
original "enhance frame fragment detection" fixes are applied, so
please apply both, even though it is a bit of overkill.

of VFs allocated. When setting the VLVF entry for the PF we need to use
the correct pool otherwise the PF will get VLAN packets from the wire
because the packet will pass VFTA filtering and the PF has the default
pool, but it will not get VLAN packets from the VFs because it has
not set the correct pool bit in the VLVF entry.

Subject: [PATCH 1553/1816] ixgbe: Allow the VF driver to be loaded before the
PF driver
The PF Reset Done bit should not be set in the extended control register
until the PF has actually completed the bring up process. It is a mis-
interpretation of the purpose of this bit to assume it should be set
when the physical reset of the device is done. Instead it should be used
to indicate to the VFs when the PF is ready to provide them with required
services. This is not until after the PF is finished coming up and ready
to process mailbox events.

Subject: [PATCH 1554/1816] ixgbe: Improve reset coordination between the PF
and the VF
Inadequate coordination between the PF driver and the VF driver results
in tx hangs in the VF driver when you perform certain actions that will
lead to a re-init of the PF. Add feature to notify active VFs when the PF
is about to re-initialize so that the VFs can take appropriate action.

After removing the skb_dma_map/unmap calls the exception handling in
igb_tx_map_adv is not correct. The issue is that the count value was not
being correctly handled so as a result we were not rewinding the ring as
back as we should have been.

Subject: [PATCH 1564/1816] IP: Send an ICMP "Fragment Reassembly Timeout"
message when enabling connection track
No matter whether connection track is enabled, an end host should send
an ICMPv4 "Fragment Reassembly Timeout" message when defrag timeout.
The reasons are following two points:
1. RFC 792 says:
>>>> >> > > If a host reassembling a fragmented datagram cannot complete the
>>>> >> > > reassembly due to missing fragments within its time limit it
>>>> >> > > discards the datagram, and it may send a time exceeded message.
>>>> >> > >
>>>> >> > > If fragment zero is not available then no time exceeded need be
>>>> >> > > sent at all.
>>>> >> > >
>>>> >> > > Read more: http://www.faqs.org/rfcs/rfc792.html#ixzz0aOXRD7Wp
2. Patrick McHardy also agrees with this opinion. :-)
About the discussion of this opinion, refer to http://patchwork.ozlabs.org/patch/41649
The patch fixed the problem like this:
When enabling connection track, fragments are received at PRE_ROUTING HOOK.
If they are failed to reassemble, ip_expire() will be called.
Before sending an ICMP "Fragment Reassembly Timeout" message,
the patch searches router table to get the destination entry only for host type.
The patch has been tested on both host type and route type.

Subject: [PATCH 1568/1816] mac80211: fix tx select key null pointer crash with
hostapd
Pavel Roskin reported a crash in ieee80211_tx_h_select_key():
http://marc.info/?l=linux-wireless&m=126419655108528&w=2
This is a regression from patch "mac80211: move control.hw_key assignment".
Fix it as suggested by Johannes, adding an else statement to make sure
that tx->key is not accessed when it's null.
Compile-tested only.

Subject: [PATCH 1571/1816] sky2: revert config space change
Obviously, this register had some other impact that is causing
the regression. Either it is masking some other access or needs
to be reset in some path.
Either, way it is best to just revert the change for 2.6.33
This reverts commit 166a0fd4c788ec7f10ca8194ec6d526afa12db75.

Subject: [PATCH 1572/1816] netns xfrm: deal with dst entries in netns
GC is non-existent in netns, so after you hit GC threshold, no new
dst entries will be created until someone triggers cleanup in init_net.
Make xfrm4_dst_ops and xfrm6_dst_ops per-netns.
This is not done in a generic way, because it woule waste
(AF_MAX - 2) * sizeof(struct dst_ops) bytes per-netns.
Reorder GC threshold initialization so it'd be done before registering
XFRM policies.

Subject: [PATCH 1573/1816] iwlwifi: fix pointer signedness warning
There are a few station addresses that are
char *, instead of the normal u8 *; gcc
gives pointer signedness warnings for some
of those, so use u8 * consistently.

Subject: [PATCH 1574/1816] ath9k: fix eeprom INI values override for 2GHz-only
cards
Among other changes, this commit:
commit 06d0f0663e11cab4ec5f2c143a118d71a12fbbe9
Author: Sujith <Sujith.Manoharan@atheros.com>
Date: Thu Feb 12 10:06:45 2009 +0530
ath9k: Enable Fractional N mode
changed the hw attach code to fix up initialization values only for
dual band devices, however the commit message did not give a reason as
to why this would be useful or necessary.
According to tests by Jorge Boncompte, this breaks at least some
2GHz-only cards, so the code should be changed back to the
unconditional INI fixup.

Subject: [PATCH 1576/1816] iwlwifi: configure missed beacon threshold
Add support to configure missed beacon threshold, by default, if receive
"missed beacon" notification from uCode and has more than 5 consecutive
beacon missed, then perform sensitivity calibration; with this change,
allow user to adjust the missed beacon threshold from debugfs in case
more sensitivity calibration required for better performance in noisy
environment
The default value (=5) should be good enough for the normal condition,
but for very noisy environment, more sensitivity calibration could help
improve the throughput, so by setting the missed beacon threshold to
lower number, user might experience better performance result.

Subject: [PATCH 1577/1816] iwlwifi: add function to reset/tune radio if needed
Adding "radio reset" function to help reset and stabilize the radio.
During normal operation, sometime for unknown reason, radio encounter
problem and can not recover by itself; the best way to
recover from it is to reset and re-tune the radio. Currently, there is
no RF reset command available, but since radio will get reset when
switching channel, use internal hw scan request to force radio
reset and get back to normal operation state.
The internal hw scan will only perform passive scan on the first
available channel (not the channel being used) in associated state. The
request should be ignored if already performing scan operation or STA is
not in associated state.
Also include an "internal_scan" debugfs file to help trigger the
internal scan from user mode.

Subject: [PATCH 1578/1816] iwlwifi: Fix A band scanning when associated
This patch allows A band to be scanned when driver is associated to AP.
Scan mechanism is that mac80211/cfg80211 requests driver to scan G band
first and then immediately to scan A band. Original code require
driver to wait for 2 seconds after any scan before another scan will be
performed. This caused driver to service G band scan request from
mac80211/cfg80211 but deny the A band scan request.

Subject: [PATCH 1579/1816] iwlwifi: Logic to control how frequent radio should
be reset if needed
Add additional logic for internal scan routine to control how
frequent this function should be performed.
The intent of this function is to reset/re-tune the radio and bring the
RF/PHY back to normal state, it does not make sense calling it too
frequent,
if reset the radio can not bring it back to normal state, it indicate
there are other reason to cause the radio not operate correctly.

Subject: [PATCH 1580/1816] iwlwifi: Tune radio to prevent unexpected behavior
We have seen the throughput dropped due to external noisy environment
and the radio is out of tune. There are lot of plcp errors indicating
this condition. Eventually the station can get de-authenticated by the
Access Point. By resetting and tuning the radio, the plcp errors are
reduced or eliminated and the throughput starts to rise.
To prevent unexpected behavior such as drop in throughput or deauthentication,
- The change provides the driver feature to monitor and tune the radio base on
the statistics notification from the uCode.
- It also allows the setting of the plcp error rate threshold via
the plcp_delta under debugfs interface.

Subject: [PATCH 1582/1816] iwlwifi: cleanup station adding code
The work done when a station is added is very similar whether the station
is added synchronously or asynchronously. Centralize this work. At the same
time increase the status flags being checked for when the command returns
with accompanying debug messages. Also increase checking when setting the
"ucode active" state with accompanying debugging.
This work is done in preparation for station notification support.

Subject: [PATCH 1583/1816] iwlwifi: make broadcast station addition generic
Add function pointer for broadcast station addition so that we can call it
in from iwlcore at a later time. We only distinguish between iwlagn and
iwl3945 broadcast station addition. For the iwl3945 station addition we add
that function to iwlcore since that is where most station functionality
resides, making it part of iwl3945 will require significant code
reorganization that will dilute station management functionality. This
seems to be an efficient solution.
It may seem as though we are removing error checking when adding the 3945
broadcast station but this error checking was never really necessary since
the function returns the station id and the broadcast station id is always
set.

Subject: [PATCH 1585/1816] iwlwifi: module parameter to enable/disable bt
co-exist
Adding "bt_coex_active" module parameter for iwlcore to enable/disable
BT coexist; if bt_coex_active is true (default), uCode will do kill/defer
every time the priority line is asserted (BT is sending signals on the
priority line in the PCIx). By disable the bt_coex_active, uCode will
ignore the BT activity and perform the normal operation.
Users might experience transmit issue on some platform due to this
WiFi/BT co-exist problem. The possible symptoms are: NetworkManager and
other similar programs can scan and find all the available APs, but will
timeout and unable to associate with any of the APs; no out-going frames
can be found with wireless sniffer tools.
On those platforms, WiFi communication can be restored by set "bt_coex_active"
module parameter to "false"

It is better to first notify cfg80211 about the hw
rfkill state (so the rfkill device that will be
registered won't have the wrong state while being
registered), and the power/tt variable init can
(and probably should) also be done first.
Also rename iwl_setup_mac to
iwl_mac_setup_register to better describe what it
really does.

the large chunk of variables can completely go

Subject: [PATCH 1591/1816] iwlwifi: cleanup spectrum measurement command
support
In iwlagn the support for spectrum measurement command has been
disabled since v2.6.29 without any requests for it. In addition to this
when this command is indeed enabled it has been found to trigger firmware
SYSASSERT on at least 4965 and 5100 hardware (see
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
this code has been bitrotting and cannot just be enabled without porting.
Remove support for spectrum measurement command from iwlagn. It can be
added back if there is a future need and the firmware problem it triggers
has been fixed. Support for the spectrim measurement notification remains
as it has been enabled all the time.
In addition to this remove the 3945 spectrum measurement command Kconfig
option and make this command always supported. The code added by this
enabling is minimal and only run when user triggers a spectrum measurement
request via sysfs.

Subject: [PATCH 1592/1816] iwlwifi: fix throughput degradation in aggregation
mode
The following commit
commit e4da8c37af626001ff704fb29ea14eb58f5f7208
Author: Johannes Berg <johannes@sipsolutions.net>
Date: Wed Dec 23 13:15:43 2009 +0100
mac80211: make off-channel work generic
triggered a bug in iwlwifi where HT parameters would not be correctly set in
some mac80211 pathways. The aggregation (and possibly other) station flags were
not being set, which limited the size of aggregation blocks and reduced
throughput at high rates.
>From Johannes:
"""
Due to Wey-Yi's patch to use the set-channel command when the channel changes
while associated, we don't get a full new RXON. Therefore, we don't re-set the
rxon-station either. However, under some circumstances that apparently have
gotten more likely mac80211 will first set up the BSS info, then add the
station and then switch to an HT channel type.
Therefore, the check for "priv->current_ht_config.is_ht" in
iwl_rxon_add_station() will hit false and not fill in the HT information.
However, that check can just be removed, which is the easiest fix for all this,
because the HT capa struct is always there, just could possibly have the
ht_supported member set to false.
"""
A sample good link in my 3x3 network improves by approximately 25% TCP
throughput. This fixes Bug 2144
(http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2144).

Subject: [PATCH 1593/1816] ath9k: improve max rate retry handling
ath9k currently forces hw->max_rate_tries to 4 to work around rate
control inefficiencies. This has some negative side effects, such as
rate_control_send_low also using a maximum of 4 tries, which could
negatively affect reliability of unicast management frames.
This patch pushes the retry limit to the rate control instead, and
allows it to use more tries on the last stage to prevent unnecessary
packet loss.

Subject: [PATCH 1594/1816] b43: Workaround circular locking in hw-tkip key
update callback
The TKIP key update callback is called from the RX path, where the driver
mutex is already locked. This results in a circular locking bug.
Avoid this by removing the lock.
Johannes noted that there is a separate bug: The callback still breaks on SDIO
hardware, because SDIO hardware access needs to sleep, but we are not allowed
to sleep in the callback due to mac80211's RCU locking.

Subject: [PATCH 1596/1816] mac80211: fix WARN_ON in the new work code
ieee80211_work_rx_mgmt currently enqueues various management frames,
including deauth and disassoc frames, however the function
ieee80211_work_rx_queued_mgmt does not handle these, as they should
only occur if the AP is buggy. It does emit a WARN_ON when this happens
though, and several users have reported such instances.
Fix the WARN_ON by not queueing such frames in the first place.

What a stupid mistake. In
commit 813d76694043d00b59475baa1fbfaf54a2eb7fad
Author: Johannes Berg <johannes@sipsolutions.net>

mac80211: move control.hw_key assignment
I inserted code testing the wrong flags field,
which means that the test is almost always true
(it's really testing for the peer's WMM support)
and thus the later parts of the stack assume hw
crypto will be done even if that's not true.
Obviously, that broke software crypto. Maxim
said so specifically, and Jochen probably uses
some cipher that iwl3945 doesn't support in
hardware, which might also explain that Maxim
reports that even hw crypto is broken.
Fix this to test the right flags field.

Subject: [PATCH 1598/1816] mac80211: track work started through callbacks
Currently, the remain_on_channel work callback needs
to track in its own data structure whether the work
was just started or not. By reordering some code this
becomes unnecessary, the generic wk->started variable
can still be 'false' on the first invocation and only
be 'true' on actual timeout invocations, so that the
extra variable can be removed.

MAC_STATS buffer
Due to a hardware bug in the SFC9000 family, the firmware must
transfer raw GMAC statistics to host memory before aggregating them
into the cooked (speed-independent) MAC statistics. Extend the stats
buffer to support this.
The length of the buffer is explicit in the MAC_STATS command, so this
change is backward-compatible on both sides.

Subject: [PATCH 1607/1816] sfc: Use fixed-size buffers for MCDI NVRAM requests
The low-level MCDI code always uses 32-bit MMIO operations, and
callers must pad input and output buffers to multiples of 4 bytes.
The MCDI NVRAM functions are not doing this. Also, their buffers are
declared as variable-length arrays with no explicit maximum length.
Switch to a fixed buffer size based on the chunk size used by the
MTD driver (which is a multiple of 4).

Subject: [PATCH 1608/1816] virtio_net: Make delayed refill more reliable
I have seen RX stalls on a machine that experienced a suspected
OOM. After the stall, the RX buffer is empty on the guest side
and there are exactly 16 entries available on the host side. As
the number of entries is less than that required by a maximal
skb, the host cannot proceed.
The guest did not have a refill job scheduled.
My diagnosis is that an OOM had occured, with the delayed refill
job scheduled. The job was able to allocate at least one skb, but
not enough to overcome the minimum required by the host to proceed.
As the refill job would only reschedule itself if it failed completely
to allocate any skbs, this would lead to an RX stall.
The following patch removes this stall possibility by always
rescheduling the refill job until the ring is totally refilled.
Testing has shown that the RX stall no longer occurs whereas
previously it would occur within a day.

Subject: [PATCH 1609/1816] ipv6: conntrack: Add member of user to
nf_ct_frag6_queue structure
The commit 0b5ccb2(title:ipv6: reassembly: use seperate reassembly queues for
conntrack and local delivery) has broken the saddr&&daddr member of
nf_ct_frag6_queue when creating new queue. And then hash value
generated by nf_hashfn() was not equal with that generated by fq_find().
So, a new received fragment can't be inserted to right queue.
The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure.

Subject: [PATCH 1612/1816] mac80211: fix NULL pointer dereference when ftrace
is enabled
I got below kernel oops when I try to bring down the network interface if
ftrace is enabled. The root cause is drv_ampdu_action() is passed with a
NULL ssn pointer in the BA session tear down case. We need to check and
avoid dereferencing it in trace entry assignment.
BUG: unable to handle kernel NULL pointer dereference

Subject: [PATCH 1614/1816] mac80211: wait for beacon before enabling powersave
Because DTIM information is required for powersave
but is only conveyed in beacons, wait for a beacon
before enabling powersave, and change the way the
information is conveyed to the driver accordingly.
mwl8k doesn't currently seem to implement PS but
requires the DTIM period in a different way; after
talking to Lennert we agreed to just have mwl8k do
the parsing itself in the finalize_join work.

Subject: [PATCH 1615/1816] starfire: clean up properly if firmware loading
fails
netdev_open() will return without cleaning up net device or hardware state
if firmware loading fails. This results in a BUG() on a second attempt to
bring the interface up, reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even
worse effects if the driver is removed afterwards.
Call netdev_close() to clean up on failure.

Subject: [PATCH 1625/1816] net/atm/mpc.c: checkpatch cleanups
Convert #include <asm... to #include <linux...
Add printk argument verification to dprintk and ddprintk
Spacing cleanups
Mostly 80 column wrapped.
printk->pr_info and pr_cont
Moved labels to column 1
Move trailing statements to new lines
switch/case cleanups
remove unnecessary breaks after returns
Remove unnecessary braces around single line statements

Hello David Miller,
I fix a bug in ks8851_mll driver, which has existed since 2.6.32-rc6.
>From : David J. Choi <david.choi@micrel.com>
Fix a bug that the data pointers in the interrupt handler are set wrong, which is related with the 5th parameter of request_irq().

Call ixgbe_copy_dcb_cfg() earlier in the ixgbe_dcbnl_set_all() so that
we can learn if this is going to fail as early as possible. Previously,
ixgbe_down or ixgbe_close were being called before this check and the
IXGBE_RESETTING bit was being set and cleared. Worse if this failed
the corresponding ixgbe_up/ndo_open would not called.

Subject: [PATCH 1652/1816] netns xfrm: xfrm6_tunnel in netns
I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
(as it should), and unregistering involves rcu barriers by itself
So it looks nothing should be done.

Subject: [PATCH 1655/1816] ps3_gelic_wireless: Remove PS3 gelic legacy wpa
support
The current PS3 gelic wireless driver has support for wireless
extensions. The original PS3 gelic wireless driver exposed a
dedicated API for a dedicated wpa_supplicant driver. This old
API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE,
however, as this is not being used by any distros, and it is being
removed from the driver and from wpa_supplicant.

Subject: [PATCH 1657/1816] sched: add head drop fifo queue
This adds an additional queuing strategy, called pfifo_head_drop,
to remove the oldest skb in the case of an overflow within the queue -
the head element - instead of the last skb (tail). To remove the oldest
skb in congested situations is useful for sensor network environments
where newer packets reflect the superior information.

Subject: [PATCH 1659/1816] cdc_ether: Partially revert "usbnet: Set link down
initially ..."
Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down
initially for drivers that update link state") changed the initial link
state in cdc_ether and other drivers based on the understanding that the
devices they support generate link change interrupts. However, this is
optional in the CDC Ethernet protocol, and two users have reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
for their devices remains down. Therefore, revert the change in
cdc_ether.

Subject: [PATCH 1661/1816] iwlwifi: optimize power saving
In hostap AP mode, every time the client sends the AP
a packet the STA_NOTIFY_AWAKE code is sent from mac80211.
This results in a command being sent to the uCode even if
the client was not asleep.
The following simple patch has fixed the issue for me without any
degradation that I can find.

There's no need to queue a work struct from
within a work struct, just move the code to
execute directly.

Subject: [PATCH 1675/1816] Bluetooth: Redo checks in IRQ handler for shared
IRQ support
Commit ac019360fe3 changed the irq handler logic to BUG_ON rather than
returning IRQ_NONE when the incoming argument is invalid. While this
works in most cases, it doesn't work when the IRQ is shared with other
devices (or when DEBUG_SHIRQ is enabled).
So revert the previous change and replace the warning message with a
comment explaining that we want this behavior.

From 6bf8268f9a91f1065c99503161ebd061492bebe3 Mon Sep 17 00:00:00 2001
From: Bastien Nocera <hadess@hadess.net>
Date: Wed, 20 Jan 2010 12:00:42 +0000
Subject: [PATCH 1677/1816] Bluetooth: Use the control channel for raw HID
reports
In commit 2da31939a42f7a676a0bc5155d6a0a39ed8451f2, support
for Bluetooth hid_output_raw_report was added, but it pushes
the data to the interrupt channel instead of the contol one.
This patch makes hid_output_raw_report use the control channel
instead. Using the interrupt channel was a mistake.

Subject: [PATCH 1692/1816] ath: make gcc check format arguments of
ath_print(), fix all misuses
Numeric channel is hard to get, so it won't be printed. Replace Mhz
with MHz on the affected lines and add commas as needed.

Subject: [PATCH 1696/1816] cfg80211: avoid flushing the global workqueue for
core reg hints
When cfg80211 starts it will send a core regulatory hint. This is
sent to the global workqueue but we force processing of it by
flushing the global workqueue. The flushing was done since
cfg80211 needs last_request to always be populated.
Avoid flushing the global workqueue by processing the work
required immediately instead of putting it into a linked
list and processing it after the flush.

Subject: [PATCH 1697/1816] cfg80211: add regulatory hint disconnect support
This adds a new regulatory hint to be used when we know all
devices have been disconnected and idle. This can happen
when we suspend, for instance. When we disconnect we can
no longer assume the same regulatory rules learned from
a country IE or beacon hints are applicable so restore
regulatory settings to an initial state.
Since driver hints are cached on the wiphy that called
the hint, those hints are not reproduced onto cfg80211
as the wiphy will respect its own wiphy->regd regardless.

The maximal size of the "ht_capa" file is 430 bytes. In most cases,

Subject: [PATCH 1705/1816] mac80211: fix sta lookup for received action frames
on an AP VLAN
When looking for a matching interface, __ieee80211_rx_handle_packet
loops over all active interfaces, looking for matching stations.
Because AP VLAN interfaces are not processed as part of this loop, it
needs to use sta_info_get_bss instead of sta_info_get in order to find
a STA that has been moved to a VLAN.
This fixes issues with aggregation setup/teardown.

Subject: [PATCH 1706/1816] mac80211: fix monitor mode tx radiotap header
handling
When an injected frame gets buffered for a powersave STA or filtered
and retransmitted, mac80211 attempts to parse the radiotap header
again, which doesn't work because it's gone at that point.
This patch adds a new flag for checking the availability of a radiotap
header, so that it only attempts to parse it once, reusing the tx info
on the next call to ieee80211_tx().
This fixes severe issues with rekeying in AP mode.

When injecting frames, mac80211 currently looks for the first AP
interface that matches the source address of the injected frame.
This breaks when such a frame is directed at a STA that has been moved
to a VLAN. This patch fixes it by using sta_info_get_bss instead of
sta_info_get, which also finds stations belonging to a VLAN interface
of the same BSS as the AP interface.

Subject: [PATCH 1711/1816] can: deny filterlist access on non-CAN interfaces
In commit 20dd3850bcf860561496827b711fa10fecf6e787 "can: Speed up CAN frame
receiption by using ml_priv" the formerly used hlist of receiver lists for
each CAN netdevice has been replaced.
The hlist content ensured only CAN netdevices to be accessed by the
can_rx_(un)register() functions which accidently dropped away together with
the hlist receiver implementation.
This patch re-introduces the check for CAN netdevices in can_rx_(un)register().

Subject: [PATCH 1712/1816] igmp: fix ip_mc_sf_allow race [v5]
Almost all igmp functions accessing inet->mc_list are protected by
rtnl_lock(), but there is one exception which is ip_mc_sf_allow(),
so there is a chance of either ip_mc_drop_socket or ip_mc_leave_group
remove an entry while ip_mc_sf_allow is running causing a crash.

Subject: [PATCH 1717/1816] lib80211: Introduce TKIP_HDR_LEN define for code
clarity
Introduce TKIP_HDR_LEN define for code clarity (in the same way as
CCMP_HDR_LEN).
Also odd len variable (not used) dropped from lib80211_tkip_hdr().

Subject: [PATCH 1718/1816] airo: fix setting zero length WEP key
Patch prevents call set_wep_key() with zero key length. That fix long
standing regression since commit c0380693520b1a1e4f756799a0edc379378b462a
"airo: clean up WEP key operations". Additionally print call trace when
someone will try to use improper parameters, and remove key.len = 0
assignment, because it is in not possible code path.

Subject: [PATCH 1721/1816] virtio: Add ability to detach unused buffers from
vrings
There's currently no way for a virtio driver to ask for unused
buffers, so it has to keep a list itself to reclaim them at shutdown.
This is redundant, since virtio_ring stores that information. So
add a new hook to do this.

Subject: [PATCH 1722/1816] virtio_net: Defer skb allocation in receive path
Date: Wed, 13 Jan 2010 12:53:38 -0800
virtio_net receives packets from its pre-allocated vring buffers, then it
delivers these packets to upper layer protocols as skb buffs. So it's not
necessary to pre-allocate skb for each mergable buffer, then frees extra
skbs when buffers are merged into a large packet. This patch has deferred
skb allocation in receiving packets for both big packets and mergeable buffers
to reduce skb pre-allocations and skb frees. It frees unused buffers by calling
detach_unused_buf in vring, so recv skb queue is not needed.

Getting it is not used, let's drop support for notifications about
(un)registered events from connector.
Another option was to check credentials on receiving, but we can always
restore it without bugs if needed, but genetlink has a wider code base
and none complained, that userspace can not get notification when some
other clients were (un)registered.
Kudos for Sebastian Krahmer <krahmer@suse.de>, who found a bug in the
code.

To fix this, the rfcomm_session_put() needs to be moved out of
rfcomm_session_timeout() into rfcomm_process_sessions(). In that
context it is perfectly fine to sleep and disconnect the socket.

Subject: [PATCH 1734/1816] Bluetooth: Do not call rfcomm_session_put() for
RFCOMM UA on closed socket
When processing a RFCOMM UA frame when the socket is closed and we were
not the RFCOMM initiator would cause rfcomm_session_put() to be called
twice during rfcomm_process_rx(). This would cause a kernel panic in
rfcomm_session_close() then.
This could be easily reproduced during disconnect with devices such as
Motorola H270 that send RFCOMM UA followed quickly by L2CAP disconnect
request. This trace for this looks like:

Avoid calling rfcomm_session_put() twice by skipping this call
in rfcomm_recv_ua() if the socket is closed.

Subject: [PATCH 1735/1816] af_key: fix netns ops ordering on module
load/unload
1. After sock_register() returns, it's possible to create sockets,
even if module still not initialized fully (blame generic module code
for that!)
2. Consequently, pfkey_create() can be called with pfkey_net_id still not
initialized which will BUG_ON in net_generic():
kernel BUG at include/net/netns/generic.h:43!
3. During netns shutdown, netns ops should be unregistered after
key manager unregistered because key manager calls can be triggered
from xfrm_user module:
general protection fault: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC
pfkey_broadcast+0x111/0x210 [af_key]
pfkey_send_notify+0x16a/0x300 [af_key]
km_state_notify+0x41/0x70
xfrm_flush_sa+0x75/0x90 [xfrm_user]
4. Unregister netns ops after socket ops just in case and for symmetry.

Subject: [PATCH 1736/1816] netlink: fix for too early rmmod
Netlink code does module autoload if protocol userspace is asking for is
not ready. However, module can dissapear right after it was autoloaded.
Example: modprobe/rmmod stress-testing and xfrm_user.ko providing NETLINK_XFRM.
netlink_create() in such situation _will_ create userspace socket and
_will_not_ pin module. Now if module was removed and we're going to call
->netlink_rcv into nothing:

Subject: [PATCH 1740/1816] MCS7830 USB-Ether: resume _with_ working link, via
.reset_resume support
ChangeLog:
Implement .reset_resume support to retain a live network connection
during suspend despite USB power loss.
- rework operation to reference cached data in mcs7830_data and
netdev->dev_addr
- update netdev->dev_addr only in case new MAC was set successfully
. Tests done:
. ethtool -d pre-/post-suspend: register values match
. running ssh session suspend, resume: works
. ifdown device, suspend, resume: works
. ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1
after card replug works)
. verified identical MAC in ifconfig post-resume
(ok, should be verified on network side to be fully certain...)
Keywords: suspend resume network connection dead interface down

Subject: [PATCH 1743/1816] can: add support for CAN interface cards based on
the PLX90xx PCI bridge
This driver is for CAN interface cards based on the PLX90xx PCI bridge.
Driver supports now:
- Adlink PCI-7841/cPCI-7841 card (http://www.adlinktech.com/)
- Adlink PCI-7841/cPCI-7841 SE card
- Marathon CAN-bus-PCI card (http://www.marathon.ru/)
- TEWS TECHNOLOGIES TPMC810 card (http://www.tews.com/)
Changes since v1:
- Added some defines for static inline int plx_pci_check_sja1000(...)
- static struct pci_device_id plx_pci_tbl[] replaced by
static DEFINE_PCI_DEVICE_TABLE(plx_pci_tbl)
- Typo fixed

Subject: [PATCH 1745/1816] dccp: fix bug in cache allocation
This fixes a bug introduced in commit de4ef86cfce60d2250111f34f8a084e769f23b16
("dccp: fix dccp rmmod when kernel configured to use slub", 17 Jan): the
vsnprintf used sizeof(slab_name_fmt), which became truncated to 4 bytes, since
slab_name_fmt is now a 4-byte pointer and no longer a 32-character array.
This lead to error messages such as
FATAL: Error inserting dccp: No buffer space available
>> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci
generated due to the truncation after the 3rd character.
Fixed for the moment by introducing a symbolic constant. Tested to fix the bug.

Subject: [PATCH 1746/1816] dccp: fix auto-loading of dccp(_probe)
This fixes commit (38ff3e6bb987ec583268da8eb22628293095d43b) ("dccp_probe:
Fix module load dependencies between dccp and dccp_probe", from 15 Jan).
It fixes the construction of the first argument of try_then_request_module(),
where only valid return codes from the first argument should be returned.
What we do now is assign the result of register_jprobe() to ret, without
the side effect of the comparison.

Subject: [PATCH 1748/1816] Bluetooth: Enter active mode before establishing a
SCO link.
When in sniff mode with a long interval time (1.28s) it can take 4+ seconds
to establish a SCO link. Fix by requesting active mode before requesting
SCO connection. This improves SCO setup time to ~500ms.
Bluetooth headsets that use a long interval time, and exhibit the long
SCO connection time include Motorola H790, HX1 and H17. They have a
CSR 2.1 chipset.
Verified this behavior and fix with host Bluetooth chipsets: BCM4329 and
TI1271.

Subject: [PATCH 1752/1816] sfc: Replace PHY MDIO test with an 'alive' test
SFC9000-family boards do not all use MDIO PHYs, so we need a different
test for PHY aliveness.
Introduce a PHY operation test_alive(). For PHYs attached to Falcon,
use a common implementation based on the existing PHY MDIO test.
For PHYs managed through MCDI, use the appropriate MCDI request.
Change test name in ethtool from 'core mdio' to 'phy alive'.
Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

Commit e5a43549f7a58509a91b299a51337d386697b92c (ixgbe: remove
skb_dma_map/unmap calls from driver) looks to have introduced a bug in
ixgbe_tx_map. If we get an error from a PCI DMA call, we loop backwards
through count until it becomes -1 and return that.
The caller of ixgbe_tx_map expects 0 on error, so return that instead.

http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg02200.html
As there was no follow up on that bug, I am submitting this
patch assuming that the other return points will not return
invalid txq's, and also that this fixes the bug (not tested).

Subject: [PATCH 1763/1816] ixgbe: only process one ixgbe_watchdog_task at a
time.
Processing multiple ixgbe_watchdog_task calls may cause
the link_up variable and IXGBE_FLAG_NEED_LINK_UPDATE flag
to be set incorrectly. In the worse case this is causing
the netif_carrier_off to be called inappropriately which
results in an interface that can't be brought up.
Although schedule_work() will only schedule the task if
it is not already on the work queue the WORK_STRUCT_PENDING
bits are cleared just before calling the work function.
This allows WORK_STRUCT_PENDING to be cleared, the work
function to start and meanwhile schedule another task.
This patch adds a mutex to the watchdog task. This bug is
actualized by changing DCB settings or doing extended
cable pull or reset tests.

Subject: [PATCH 1765/1816] e1000: call pci_save_state after pci_restore_state
This patch adds a call to pci_save_state() immediately after
the call to pci_restore_state(). Due to a change in the behavior
of pci_restore_state() it is necessary to call pci_save_state()
to keep the state_saved flag. This patch is based on a similar
patch for ixgbe.

Subject: [PATCH 1766/1816] ixgbe: Allocate driver resources per NUMA node
The default policy for the current driver is to do all its memory
allocation on whatever processor is running insmod/modprobe. This
is less than optimal.
This driver's default mode of operation will be to use each node for each
subsequent transmit/receive queue. The most efficient allocation will be
to then have the interrupts bound in such a way as to match up the
interrupt of the queue to the cpu where its memory was allocated.

Subject: [PATCH 1767/1816] ixgbe: Make descriptor ring allocations NUMA-aware
This patch allocates the ring structures themselves on each
NUMA node along with the buffer_info structures. This way we
don't allocate the entire ring memory on a single node in one
big block, thus reducing NUMA node memory crosstalk.

Subject: [PATCH 1775/1816] mISDN: positive error return should be negative in
mode_hfcmulti()
The error return should be negative. Its only caller that acts upon its
return, handle_bmsg(), transmits the positive error but can also return
negative errors.

Subject: [PATCH 1777/1816] net: maintain namespace isolation between vlan and
real device
In the vlan and macvlan drivers, the start_xmit function forwards
data to the dev_queue_xmit function for another device, which may
potentially belong to a different namespace.
To make sure that classification stays within a single namespace,
this resets the potentially critical fields.

to extend it with the macvtap backend that provides
a tun/tap compatible interface directly on the macvlan

Subject: [PATCH 1779/1816] net: macvtap driver
In order to use macvlan with qemu and other tools that require
a tap file descriptor, the macvtap driver adds a small backend
with a character device with the same interface as the tun
driver, with a minimum set of features.
Macvtap interfaces are created in the same way as macvlan
interfaces using ip link, but the netif is just used as a
handle for configuration and accounting, while the data
goes through the chardev. Each macvtap interface has its
own character device, simplifying permission management
significantly over the generic tun/tap driver.

From bf66f3736a945dd4e92d86427276c6eeab0a6c1d Mon Sep 17 00:00:00 2001
From: Christian Pellegrin <chripell@fsfe.org>

Subject: [PATCH 1783/1816] can: mcp251x: Move to threaded interrupts instead
of workqueues.
This patch addresses concerns about efficiency of handling incoming
packets. Handling of interrupts is done in a threaded interrupt handler
which has a smaller latency than workqueues. This change needed a rework
of the locking scheme that was much simplified. Some other (more or less
longstanding) bugs are fixed: utilization of just half of the RX
buffers, useless wait for interrupt on open, more reliable reset
sequence. The MERR interrupt is not used anymore: it overloads the CPU
in error-passive state without any additional information. One shot mode
is disabled because it's not clear if it can be handled efficiently on
this CAN controller.

Subject: [PATCH 1785/1816] sky2: hand receive DMA mapping failures
If receive buffer mapping failed, then it was possible to get
stuck with unmapped receive buffer in DMA ring.
This would be an extremely rare condition because the driver had just
released the map for the last receive so it should be able to get
another map again (in soft-irq).

Subject: [PATCH 1789/1816] igb: make certain to reassign legacy interrupt
vectors after reset
This change corrects an issue that will cause false hangs when using either
82575 or 82580 in legacy interrupt mode. The issue is caused when there is
a slow traffic flow and an "ethtool -r" is executed while using legacy or
MSI interrupts. MSI-X is not affected by this issue due to the fact that
we were already reconfiguring the vectors after reset.
If possible it would be best to push this for net-2.6 since it is resolving
a bug but if that is not possible then net-next-2.6 will be fine.

Subject: [PATCH 1790/1816] net: use helpers to access mc list V2
This patch introduces the similar helpers as those already done for uc list.
However multicast lists are no list_head lists but "mademanually". The three
macros added by this patch will make the transition of mc_list to list_head
smooth in two steps:
1) convert all drivers to use these macros (with the original iterator of type
"struct dev_mc_list")
2) once all drivers are converted, convert list type and iterators to "struct
netdev_hw_addr" in one patch.
>From now on, drivers can (and should) use "netdev_for_each_mc_addr" to iterate
over the addresses with iterator of type "struct netdev_hw_addr". Also macros
"netdev_mc_count" and "netdev_mc_empty" to read list's length. This is the state
which should be reached in all drivers.

Subject: [PATCH 1792/1816] qlge: Add watchdog timer.
Add periodic heartbeat register read to trigger the eeh
recovery process.
We see cases where an eeh error was injected and the slot was
suspended. An asic access attempt is required to flush the recovery process,
but without interrupts the process can stall.
Adding this periodic register read causes the recovery process to begin.

Subject: [PATCH 1798/1816] packet: Add GSO/csum offload support.
This patch adds GSO/checksum offload to af_packet sockets using
virtio_net_hdr. Based on Rusty's patch to add this support to tun.
It allows GSO/checksum offload to be enabled when using raw socket
backend with virtio_net.
Adds PACKET_VNET_HDR socket option to prepend virtio_net_hdr in the
receive path and process/skip virtio_net_hdr in the send path. This
option is only allowed with SOCK_RAW sockets attached to ethernet
type devices.
v2 updates
----------
Michael's Comments
- Perform length check in packet_snd() when GSO is off even when
vnet_hdr is present.
- Check for SKB_GSO_FCOE type and return -EINVAL
- don't allow tx/rx ring when vnet_hdr is enabled.
Herbert's Comments
- Removed ethernet specific code.
- protocol value is assumed to be passed in by the caller.

Subject: [PATCH 1805/1816] Bluetooth: Keep a copy of each HID device's report
descriptor
The report descriptor is read by user space (via the Service
Discovery Protocol), so it is only available during the ioctl
to connect. However, the HID probe function that needs the
descriptor might not be called until a specific module is
loaded. Keep a copy of the descriptor so it is available for
later use.

Subject: [PATCH 1806/1816] packet: Kill CONFIG_PACKET_MMAP.
Early on this was an experimental facility that few
people other than Alexey Kuznetsov played with.
Now it's a pretty fundamental thing and as people add
more features to AF_PACKET sockets this config options

Subject: [PATCH 1807/1816] netfilter: nf_conntrack: fix memory corruption with
multiple namespaces
As discovered by Jon Masters <jonathan@jonmasters.org>, the "untracked"
conntrack, which is located in the data section, might be accidentally
freed when a new namespace is instantiated while the untracked conntrack
is attached to a skb because the reference count it re-initialized.
The best fix would be to use a seperate untracked conntrack per
namespace since it includes a namespace pointer. Unfortunately this is
not possible without larger changes since the namespace is not easily
available everywhere we need it. For now move the untracked conntrack
initialization to the init_net setup function to make sure the reference
count is not re-initialized and handle cleanup in the init_net cleanup
function to make sure namespaces can exit properly while the untracked
conntrack is in use in other namespaces.

Subject: [PATCH 1808/1816] netfilter: nf_conntrack: per netns
nf_conntrack_cachep
nf_conntrack_cachep is currently shared by all netns instances, but
because of SLAB_DESTROY_BY_RCU special semantics, this is wrong.
If we use a shared slab cache, one object can instantly flight between
one hash table (netns ONE) to another one (netns TWO), and concurrent
reader (doing a lookup in netns ONE, 'finding' an object of netns TWO)
can be fooled without notice, because no RCU grace period has to be
observed between object freeing and its reuse.
We dont have this problem with UDP/TCP slab caches because TCP/UDP
hashtables are global to the machine (and each object has a pointer to
its netns).
If we use per netns conntrack hash tables, we also *must* use per netns
conntrack slab caches, to guarantee an object can not escape from one
namespace to another one.

Subject: [PATCH 1811/1816] netfilter: nf_conntrack: fix hash resizing with
namespaces
As noticed by Jon Masters <jonathan@jonmasters.org>, the conntrack hash
size is global and not per namespace, but modifiable at runtime through
/sys/module/nf_conntrack/hashsize. Changing the hash size will only
resize the hash in the current namespace however, so other namespaces
will use an invalid hash size. This can cause crashes when enlarging
the hashsize, or false negative lookups when shrinking it.
Move the hash size into the per-namespace data and only use the global
hash size to initialize the per-namespace value when instanciating a
new namespace. Additionally restrict hash resizing to init_net for
now as other namespaces are not handled currently.

Subject: [PATCH 1812/1816] dst: call cond_resched() in dst_gc_task()
Kernel bugzilla #15239
On some workloads, it is quite possible to get a huge dst list to
process in dst_gc_task(), and trigger soft lockup detection.
Fix is to call cond_resched(), as we run in process context.
