Subject: [PATCH 0003/1267] kconfig: fix /dev/null breakage
While running "make menuconfig" and "make mrproper"
some people experienced that /dev/null suddenly changed
permissions or suddenly became a regular file.
The main reason was that /dev/null was used as output
to gcc in the check-lxdialog.sh script and gcc did
some strange things with the output file; in this
case /dev/null when it errorred out.
Following patch implements a suggestion
from Bryan O'Sullivan <bos@serpentine.com> to
use gcc -print-file-name=libxxx.so.
Also the Makefile is adjusted to not resolve value of
HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.
This prevents us from calling gcc when running make *clean/mrproper
Thanks to Eyal Lebedinsky <eyal@eyal.emu.id.au> and
Jean Delvare <khali@linux-fr.org> for the first error reports.

Make flush_tlb_all_local take a void * so it doesn't have to be cast

is a macro.
Also remove the prototype of flush_tlb_all_local from .c files.

From cb6fc18e9ca615f03d18e60c49855b434ca2e51e Mon Sep 17 00:00:00 2001
From: Helge Deller <deller@parisc-linux.org>
Date: Tue, 17 Jan 2006 12:40:40 -0700
Subject: [PATCH 0008/1267] [PARISC] Use kzalloc and other janitor-style
cleanups
Helge,
o Convert a bunch of kmalloc/memset uses to kzalloc.
o pci.c: Add some __read_mostly annotations.
o pci.c: Move constant pci_post_reset_delay to asm/pci.h
o grfioctl.h: Add A4450A to comment of CRT_ID_VISUALIZE_EG.
o Add some consts to perf.c/perf_images.h
Matthew,
o sticore.c: Add some consts to suppress compile warnings.

Subject: [PATCH 0009/1267] [PARISC] Remove unnecessary extern declarations
from asm/pci.h
Remove two unnecessary extern declarations from asm/pci.h.
They collide with what gcc4.0 assumed was static (and should be static).
Found by Joel Soete.

Subject: [PATCH 0010/1267] [PARISC] pdc_stable version 0.22
pdc_stable v0.22, changes since v0.10:
o renamed root subsystem from 'pdc' to 'stable'
o split 'info' into several files, one per PDC field
o implemented 'autoboot' and 'autosearch' write calls to toggle
these flags
o grant read permission to all users on "safe" files
o more code cleanup (removed duplicate code)
o avoid bad stable storage clobbering by write locking critical sections
o print consistent data as well
o SMP cleanups

Subject: [PATCH 0017/1267] [PARISC] Remove obsolete _hlt cruft
Remove a bunch of obsolete code from process.c, these routines were
likely imported from the i386 version of process.c when the port
started. The routines are only used in floppy.c, which I seriously
doubt will ever work on parisc, due to architectural assumptions.

Subject: [PATCH 0018/1267] [PARISC] Add chassis_power_off routine
Define a chassis_power_off routine that machines which have a way
to turn off the power supply can hook into. Formerly they were
using pm_power_off, which is now being used by generic code. Make
lasi.c use chassis_power_off instead of pm_power_off.
Note, all machines need to call machine_power_off so that the
switch can power off the machine, though halt -p may not necessarily
be able to work properly on the machine.

Subject: [PATCH 0023/1267] [PARISC] Arch-specific compat signals
Add enough arch-specific compat signals code to enable parisc64
to compile and boot out of the mainline tree. There are likely still
many dragons here, but this is a start to squashing the last
big difference between the mainline tree and the parisc-linux tree.
The remaining bugs can be squashed as they come up.

Subject: [PATCH 0028/1267] V4L/DVB (3405): Fixes tvp5150a/am1 detection.
- Tvp5150 type were determined by a secondary register instead of
using ROM code.
- tvp5150am1 have ROM=4.0, while tvp5150a have ROM=3.33 (decimal).
All other ROM versions are reported as unknown tvp5150.
- Except for reporting, current code doesn't enable any special feature
for tvp5150am1 or tvp5150a. Code should work for both models (but were
tested only for tvp5150am1).

Subject: [PATCH 0042/1267] [IA64-SGI] Recursive flags do not work for
selective builds
arch/ia64/sn/Makefile sets CPPFLAGS, expecting that setting to
propogate to all the subdirectories. For a normal build with its
recursive descent it does work, but doing a selective build like
'make arch/ia64/sn/kernel/io_init.i' does not do a recursive descent,
it goes directly to arch/ia64/sn/kernel/Makefile so the flags do not
get set.
To support selective builds, set the flags in all the subordinate Makefiles.

Subject: [PATCH 0043/1267] [PATCH] drivers/sn/ must be entered for
CONFIG_SGI_IOC3
Actually I think this is more appropriate so we don't end up with 17
cases that add drivers/sn to the build lib.
Include drivers/sn when CONFIG_IA64_SGI_SN2 or CONFIG_IA64_GENERIC
is enabled.

Subject: [PATCH 0044/1267] [IA64-SGI] Update TLB flushing code for SN platform
This patch finishes support for SHUB2 (the new chipset). Most of the
changes are performance related. A few changes are workarounds for
"interesting" chipset features.
Some temporary debugging code has also been deleted.

Subject: [PATCH 0046/1267] [libata sata_sil] implement 'slow_down' module
parameter
On occasion, a user will submit a patch that enables the "mod15write"
quirk for their device. Enabling this quirk has the effect of clamping
all ATA commands to no more than 15 sectors. The intended use of this
quirk is to stop the controller from generating FIS's of unusual size
("but Wesley, what about the FOUS's?"), which in turn works around
problems in a <list> of hard drives.
One side effect of this quirk is greatly decreased performance. Users
often enable the mod15write quirk to fix various system, power, chip,
and/or driver problems. For a few rare problematic cases, enabling this
has cured lockups or data corruption.
Rather than add bogus listings to the mod15write quirk list (I get a
patch every month doing such), we add a 'slow_down' module parameter.
This allows users to employ a performance sledgehammer in the hopes
of curing a problem. It defaults to off (0), of course.

Subject: [PATCH 0047/1267] r8169: prevent excessive busy-waiting
The MII registers read/write function blindly busy waits for an
amount of 1000 us (1 ms), then up to 200 ms. These functions are
called from irq disabled context. Depending on the clock management,
it triggers lost ticks events. Since the value is way above the
standard delay required for mii register access, it strangely looks
like a bandaid against posted writes.

Subject: [PATCH 0059/1267] [ARM] 3295/1: Fix oprofile init return value
Patch from Russ Dill
The oprofile init code was broken in commit c6b9da. The new logic will
always return -ENODEV. This fixes oprofile_arch_init to return 0 on
success, and return the return value of spec->init() if applicable.

Subject: [PATCH 0061/1267] [ARM] 3286/2: S3C2400 - adds to the table of
supported CPUs
Patch from Lucas Correia Villa Real
Oops, sorry for the typo on name_s3c2400, a new patch is attached.
About GSTATUS1, S3C2400 doesn't have that register, so it's not
safe to use that memory address to identify its CPU.

Subject: [PATCH 0063/1267] [SERIAL] SIIG 8-port serial boards support
This patch adds support for SIIG 8-port boards. These boards have 4 ports in
separate bars and another 4 ports in the single bar. Because of this strange
port arrangement these cards need special setup function. Fortunately no other
SIIG cards have more than 4 port, so this setup function could be used for them
too.

Subject: [PATCH 0064/1267] [SERIAL] initialize spinlock for port failed to
setup console
It seems serial_core intend to initialize port->lock just once for each
ports. This is done in uart_set_options() for console, and in
uart_add_one_port() for other ports. But there is a case the port->lock is
not initialized by serial_core. If the setup function for the console was
failed, it will not call uart_set_options() but the port is marked as
console (uart_console(port) returns 1). It can happen if console was PCI
port which can not detected at the time of register_console.
This patch is to initialize port->lock for such console port. With this
change, most of spin_lock_init() (some of them are labeled "Temporary
fix.") in low-level serial drivers can be omitted.

Subject: [PATCH 0065/1267] [libata sata_mv] do not enable PCI MSI by default
Several bug reports have come in, noting that disabling CONFIG_PCI_MSI
has fixed their problems with this driver. This may be generic system
issues, but there is also the probability of unimplemented hardware
errata workarounds. Until this ream of bug reports is sorted out, we
can get them going in non-MSI interrupt mode.
As such, this change adds an 'msi' module option, which defaults to off.

With the recent optimization made to wrap_mmu_context function,
we don't hold tasklist_lock anymore when wrapping context id.
The comments in asm/system.h must fall through the crack earlier.
Remove staled comments.
I believe it is still beneficial to unlock the runqueue lock
across context switch. So leave __ARCH_WANT_UNLOCKED_CTXSW on.

Redirecting interrupts using smp_affinity on altix does not work on kernels

if MSI is built in. This patch calls move_native_irq() instead of move_irq()

This is to work around a defect in HP rx5670 firmware: when an interrupt
occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked
"in-service", which leaves the interrupt (and others of equal or lower

* sleep to allow some time for heartbeat state to catch up to network
* extra debug info for bad recovery state problems
* make DLM_RECO_NODE_DATA_DONE a valid state for non-master recovery nodes
* prune all locks from dead nodes on $RECOVERY lock resources
* do NOT automatically add new nodes to mle nodemaps until they have properly
joined the domain
* make sure dlm_pick_recovery_master only exits when all nodes have synced
* properly handle dlmunlock errors in dlm_pick_recovery_master
* do not propagate network errors in dlm_send_begin_reco_message
* dead nodes were not being put in the recovery map sometimes, fix this

Subject: [PATCH 0088/1267] configfs: Add permission and ownership to configfs
objects.
configfs always made item and attribute ownership root.root and
permissions based on a umask of 022. Add ->setattr() to allow
chown(2)/chmod(2), and persist the changes for the lifetime of the
items and attributes.

Subject: [PATCH 0090/1267] [PATCH] ocfs2: don't wait on recovery when locking
journal
The mount path had incorrectly asked the locking code to wait for recovery
completion, which deadlocks things because recovery waits for mount to
complete first.

From: Mark Haverkamp <markh@osdl.org>
Date: Wed, 1 Feb 2006 09:30:31 -0800
Subject: [PATCH 0101/1267] [SCSI] aacraid: reduce device probe warnings
Received from Mark Salyzyn.
This patch sets up some device quirks surrounding arrays to inform the
scsi layer that various mode pages are not supported. This reduces the
severity of the complaints that show up in the logs as the array devices
are enumerated.

Subject: [PATCH 0103/1267] [SCSI] aacraid: use no_uld_attach flag
Received From Mark Salyzyn.
In order to support user tools accessing the array components (SMART,
Mode Page information, Cache page adjustments, WWN determination,
Firmware updates etc), we take advantage of the no_uld_attach flag and
deprecate the code that filters Inquiries to block the requests to array
components. The quirk prevents the sd layer from attaching to the
components.
We also took the opportunity to balance the queue depths based on the
total adapter queue depth to the array devices to reduce the chances of
starvation.

Subject: [PATCH 0104/1267] [SCSI] iscsi update: cleanup iscsi class interface
From:
michaelc@cs.wisc.edu
fujita.tomonori@lab.ntt.co.jp
da-x@monatomic.org
and err path fixup from:
ogerlitz@voltaire.com
This patch cleans up that interface by having the lld and class
pass a iscsi_cls_session or iscsi_cls_conn between each other when
the function is used by HW and SW iscsi llds. This way the lld
does not have to remember if it has to send a handle or pointer
and a handle or pointer to connection, session or host.
This also has the class verify the session handle that gets passed from
userspace instead of using the pointer passed into the kernel directly.

If the transport lookup fails we set the daemon pid too late.
This can cause us deadlock since the netlink code will think we
meant to call back into our iscsi_if_rx function.

This patch is last becuase I was not sure if this patchset was
going to be applied over the kmalloc2kzalloc one by JesS. If it
is then this patch will not apply and can be dropped for now. I will
resend later when things setttle down.

Subject: [PATCH 0127/1267] [PATCH] x86_64: Allow to run main time keeping from
the local APIC interrupt
Another piece from the no-idle-tick patch.
This can be enabled with the "apicmaintimer" option.
This is mainly useful when the PIT/HPET interrupt is unreliable.
Note there are some systems that are known to stop the APIC
timer in C3. For those it will never work, but this case
should be automatically detected.
It also only works with PM timer right now. When HPET is used
the way the main timer handler computes the delay doesn't work.
It should be a bit more efficient because there is one less
regular interrupt to process on the boot processor.
Requires earlier bugfix from Venkatesh

Subject: [PATCH 0131/1267] [PATCH] x86_64: Undo the earlier changes to remove
unrolled copy/memset functions
They cause quite bad performance regressions on Netburst
This is temporary until we can get new optimized functions
for these CPUs.
This undoes changes that were done in 2.6.15 and in 2.6.16-rc1,
essentially bringing the code back to 2.6.14 level. Only change
is I renamed the X86_FEATURE_K8_C flag to X86_FEATURE_REP_GOOD
and fixed the check for the flag and also fixed some comments.

Subject: [PATCH 0132/1267] [PATCH] x86_64: Fix the node cpumask of a cpu going
down
Currently, x86_64 and ia64 arches do not clear the corresponding bits
in the node's cpumask when a cpu goes down or cpu bring up is cancelled.
This is buggy since there are pieces of common code where the cpumask is
checked in the cpu down code path to decide on things (like in the slab
down path). PPC does the right thing, but x86_64 and ia64 don't (This
was the reason Sonny hit upon a slab bug during cpu offline on ppc and
could not reproduce on other arches). This patch fixes it for x86_64.
I won't attempt ia64 as I cannot test it.
Credit for spotting this should go to Alok.

attached patch is 2 more cases i found via running the reference_init.pl
script. These were easy to spot just knowing the file names. There is
one another about init/main.c that i cant exactly zero in. (partly
because i dont know how to interpret the data thats spewed out of the tool).

Subject: [PATCH 0141/1267] [PATCH] x86_64: When allocation of merged SG lists
fails in the IOMMU don't merge
[ AK: I redid Kevin's fix to be simpler, but the idea and original
analysis of the problem is from Kevin]
This avoid allocation failures on some SATA systems like Nvidia CK8
when the IOMMU gets fragmented. Modern SATA devices have quite large queues
(128 entries) and the FS with ext2/3 is good enough now that it often
passes whole 128 page sg lists down to the driver. These require
512K of continuous free space in the IOMMU aperture to map when merged.
When the IOMMU is fragmented this could lead to spurious IO errors
due to failing mappings.
Short term fix is to just try to map the SG list again unmerged
page by page - this way fragmentation doesn't matter anymore.
The code for that was already there, but it just wasn't enabled for the
merge case.
According to Kevin at least the Nvidia device doesn't seem to benefit
from merging much anyways, so the only slowdown is from trying
to do an unnecessary merge attempt.
Kevin plans to implement better fragmentation avoidance in the future,
but that wouldn't be 2.6.16 material.
TBD: should add some statistic counters to count how often that really
happens.

Subject: [PATCH 0144/1267] [PATCH] x86_64: Calibrate APIC timer using PM timer
On some broken motherboards (at least one NForce3 based AMD64 laptop)
the PIT timer runs at a incorrect frequency. This patch adds a new
option "apicpmtimer" that allows to use the APIC timer and calibrate it
using the PMTimer. It requires the earlier patch that allows to run the
main timer from the APIC.
Specifying apicpmtimer implies apicmaintimer.
The option defaults to off for now.
I tested it on a few systems and the resulting APIC timer frequencies
were usually a bit off, but always <1%, which should be tolerable.
TBD figure out heuristic to enable this automatically on the affected
systems TBD perhaps do it on all NForce3s or using DMI?

Subject: [PATCH 0147/1267] [PATCH] x86_64: Dont record local apic ids when
they are disabled in MADT
Some broken BIOS's had processors disabled, but
same apic id as a valid processor. This causes
acpi_processor_start() to think this disabled
cpu is ok, and croak. So we dont record bad
apicid's anymore.

Subject: [PATCH 0149/1267] [PATCH] x86_64: Let impossible CPUs point to
reference per cpu data
Hack for 2.6.16. In 2.6.17 all code that uses NR_CPUs should
be audited and changed to only touch possible CPUs.
Don't mark the reference per cpu data init data (so it stays
around after boot) and point all impossible CPUs to it. This way
they reference some valid - although shared memory. Usually
this is only initialization like INIT_LIST_HEADs and there
won't be races because these CPUs never run. Still somewhat hackish.

Subject: [PATCH 0150/1267] [PATCH] x86_64: IOMMU printk cleanup
This patch contains a printk reorder to remove the current problem of
displaying "PCI-DMA: Disabling IOMMU." and then "PCI-DMA: using GART
IOMMU" 20 lines later in dmesg.
It also constains a printk reorder in swiotlb to state swiotlb
enablement prior to describing the location of the bounce buffers, and a
printk reorder to state gart enablement prior to describing the
aperature.
Also constains a whitespace cleanup in arch/x86_64/kernel/setup.c
Tested (along with patch 2/2) on dual opteron with gart enabled,
iommu=soft, and iommu=off.

Subject: [PATCH 0155/1267] [NETFILTER]: ULOG/nfnetlink_log: Use better default
value for 'nlbufsiz'
Performance tests showed that ULOG may fail on heavy loaded systems
because of failed order-N allocations (N >= 1).
The default value of 4096 is not optimal in the sense that it actually
allocates _two_ contigous physical pages. Reasoning: ULOG uses
alloc_skb(), which adds another ~300 bytes for skb_shared_info.
This patch sets the default value to NLMSG_GOODSIZE and adds some
documentation at the top.

Subject: [PATCH 0161/1267] [NETFILTER]: Fix possible overflow in netfilters
do_replace()
netfilter's do_replace() can overflow on addition within SMP_ALIGN()
and/or on multiplication by NR_CPUS, resulting in a buffer overflow on
the copy_from_user(). In practice, the overflow on addition is
triggerable on all systems, whereas the multiplication one might require
much physical memory to be present due to the check above. Either is
sufficient to overwrite arbitrary amounts of kernel memory.
I really hate adding the same check to all 4 versions of do_replace(),
but the code is duplicate...

comparison and the data structure used for userspace communication. Unify
the data structures to break compatiblity now (before it is released), so
we can port it to x_tables in 2.6.17.

Subject: [PATCH 0165/1267] [NETFILTER]: Fix check whether dst_entry needs to
be released after NAT
After DNAT the original dst_entry needs to be released if present
so the packet doesn't skip input routing with its new address. The
current check for DNAT in ip_nat_in is reversed and checks for SNAT.

Subject: [PATCH 0171/1267] Revert "[PATCH] x86_64: Fix the node cpumask of a
cpu going down"
This reverts commit 10f4dc8b27ac42f930ac55adb8c521264dc997f8.
Quoth Andi Kleen:
"Kiran decided that it makes the problem worse than it was before.
Fixing it fully requires more work which is too much for 2.6.16. So
please revert that commit for now."

Don't map zero-length requests in gdth, zome architectures don't like
that in their dma mapping routines.

Subject: [PATCH 0173/1267] [PATCH] percpu data: only iterate over possible
CPUs
percpu_data blindly allocates bootmem memory to store NR_CPUS instances of
cpudata, instead of allocating memory only for possible cpus.
As a preparation for changing that, we need to convert various 0 -> NR_CPUS
loops to use for_each_cpu().
(The above only applies to users of asm-generic/percpu.h. powerpc has gone it
alone and is presently only allocating memory for present CPUs, so it's
currently corrupting memory).

Subject: [PATCH 0174/1267] [PATCH] fix ordering on requeued request drainage
Previously, if a fs request which was being drained failed and got
requeued, blk_do_ordered() didn't allow it to be reissued, which causes
queue stall. This patch makes blk_do_ordered() use the sequence of each
request to determine whether a request can be issued or not. This fixes
the bug and simplifies code.

Subject: [PATCH 0180/1267] [PATCH] pktcdvd: Fix overflow for discs with large
packets
The pktcdvd driver was using an 8 bit field to store the packet length
obtained from the disc track info. This causes it to overflow packet length
values of 128KB or more. I changed the field to 32 bits to fix this.
The pktcdvd driver defaulted to its maximum allowed packet length when it
detected a 0 in the track info field. I changed this to fail the operation
and refuse to access the media. This seems more sane than attempting to
access it with a value that almost certainly will not work.

Subject: [PATCH 0184/1267] [PATCH] pktcdvd: Allow larger packets
The pktcdvd driver uses a compile time macro constant to define the maximum
supported packet length. I changed this from 32 sectors to 128 sectors
because that allows over 100 MB of additional usable space on a 700 MB cdrw,
and increases throughput.
Note that you need a modified cdrwtool program that can format a CDRW disc
with larger packets to benefit from this change.

Subject: [PATCH 0189/1267] [PATCH] jbd: fix transaction batching
Ben points out that:
When writing files out using O_SYNC, jbd's 1 jiffy delay results in a
significant drop in throughput as the disk sits idle. The patch below
results in a 4-5x performance improvement (from 6.5MB/s to ~24-30MB/s on my
IDE test box) when writing out files using O_SYNC.
So optimise the batching code by omitting it entirely if the process which is
doing a sync write is the same as the one which did the most recent sync
write. If that's true, we're unlikely to get any other processes joining the
transaction.
(Has been in -mm for ages - it took me a long time to get on to performance
testing it)
Numbers, on write-cache-disabled IDE:
/usr/bin/time -p synctest -n 10 -uf -t 1 -p 1 dir-name
Unpatched:
40 seconds
Patched:
35 seconds
Batching disabled:
35 seconds
This is the problematic single-process-doing-fsync case. With multiple
fsyncing processes the numbers are AFACIT unaltered by the patch.
Aside: performance testing and instrumentation shows that the transaction
batching almost doesn't help (testing with synctest -n 1 -uf -t 100 -p 10
dir-name on non-writeback-caching IDE). This is because by the time one
process is running a synchronous commit, a bunch of other processes already
have a transaction handle open, so they're all going to batch into the same
transaction anyway.
The batching seems to offer maybe 5-10% speedup with this workload, but I'm
pretty sure it was more important than that when it was first developed 4-odd
years ago...

Subject: [PATCH 0191/1267] [PATCH] NUMA slab locking fixes: move color_next to
l3
colour_next is used as an index to add a colouring offset to a new slab in the
cache (colour_off * colour_next). Now with the NUMA aware slab allocator, it
makes sense to colour slabs added on the same node sequentially with
colour_next.
This patch moves the colouring index "colour_next" per-node by placing it on
kmem_list3 rather than kmem_cache.
This also helps simplify locking for CPU up and down paths.

Subject: [PATCH 0192/1267] [PATCH] NUMA slab locking fixes: irq disabling from
cahep->spinlock to l3 lock
Earlier, we had to disable on chip interrupts while taking the
cachep->spinlock because, at cache_grow, on every addition of a slab to a slab
cache, we incremented colour_next which was protected by the cachep->spinlock,
and cache_grow could occur at interrupt context. Since, now we protect the
per-node colour_next with the node's list_lock, we do not need to disable on
chip interrupts while taking the per-cache spinlock, but we just need to
disable interrupts when taking the per-node kmem_list3 list_lock.

Subject: [PATCH 0193/1267] [PATCH] NUMA slab locking fixes: fix cpu down and
up locking
This fixes locking and bugs in cpu_down and cpu_up paths of the NUMA slab
allocator. Sonny Rao <sonny@burdell.org> reported problems sometime back on
POWER5 boxes, when the last cpu on the nodes were being offlined. We could
not reproduce the same on x86_64 because the cpumask (node_to_cpumask) was not
being updated on cpu down. Since that issue is now fixed, we can reproduce
Sonny's problems on x86_64 NUMA, and here is the fix.
The problem earlier was on CPU_DOWN, if it was the last cpu on the node to go
down, the array_caches (shared, alien) and the kmem_list3 of the node were
being freed (kfree) with the kmem_list3 lock held. If the l3 or the
array_caches were to come from the same cache being cleared, we hit on
badness.
This patch cleans up the locking in cpu_up and cpu_down path. We cannot
really free l3 on cpu down because, there is no node offlining yet and even
though a cpu is not yet up, node local memory can be allocated for it. So l3s
are usually allocated at keme_cache_create and destroyed at
kmem_cache_destroy. Hence, we don't need cachep->spinlock protection to get
to the cachep->nodelist[nodeid] either.
Patch survived onlining and offlining on a 4 core 2 node Tyan box with a 4
dbench process running all the time.

Subject: [PATCH 0194/1267] [PATCH] VFS: Ensure LOOKUP_CONTINUE flag is
preserved by link_path_walk()
When walking a path, the LOOKUP_CONTINUE flag is used by some filesystems
(for instance NFS) in order to determine whether or not it is looking up
the last component of the path. It this is the case, it may have to look
at the intent information in order to perform various tasks such as atomic
open.
A problem currently occurs when link_path_walk() hits a symlink. In this
case LOOKUP_CONTINUE may be cleared prematurely when we hit the end of the
path passed by __vfs_follow_link() (i.e. the end of the symlink path)
rather than when we hit the end of the path passed by the user.
The solution is to have link_path_walk() clear LOOKUP_CONTINUE if and only
if that flag was unset when we entered the function.

Subject: [PATCH 0196/1267] [PATCH] i386 cpu hotplug: don't access freed memory
i386 CPU init code accesses freed init memory when booting a newly-started
processor after CPU hotplug. The cpu_devs array is searched to find the
vendor and it contains pointers to freed data.
Fix that by:
1. Zeroing entries for freed vendor data after bootup.
2. Changing Transmeta, NSC and UMC to all __init[data].
3. Printing a warning (once only) and setting this_cpu
to a safe default when the vendor is not found.
This does not change behavior for AMD systems. They were broken already
but no error was reported.

Subject: [PATCH 0200/1267] [PATCH] kconfig: detect if -lintl is needed when
linking conf,mconf
On a system where libintl.h is present, but the NLS functionality is
supplied by a separate library instead of the system C library, an attempt
to "make config" or "make menuconfig" will fail with link errors, ex:
scripts/kconfig/mconf.o:mconf.c:(.text+0xf63): undefined reference to
`_libintl_gettext'
This patch attempts to correct the problem by detecting whether or not NLS
support requires linking with libintl.

Subject: [PATCH 0201/1267] mm/slab.c (non-NUMA): Fix compile warning and clean
up code
The non-NUMA case would do an unmatched "free_alien_cache()" on an alien
pointer that had never been allocated.
It might not matter from a code generation standpoint (since in the
non-NUMA case, the code doesn't actually _do_ anything), but it not only
results in a compiler warning, it's really really ugly too.
Fix the compiler warning by just having a matching dummy allocation.
That also avoids an unnecessary #ifdef in the code.

+ Prefix: 'f71805f'
+ Addresses scanned: none, address read from Super I/O config space
+ Datasheet: Provided by Fintek on request

+
+Thanks to Denis Kieft from Barracuda Networks for the donation of a

+for providing initial documentation.

+
+Thanks to Chris Lin from Jetway for providing wiring schematics and
+anwsering technical questions.
+
+
+Description
+-----------
+
+The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
+capabilities. It can monitor up to 9 voltages (counting its own power
+source), 3 fans and 3 temperature sensors.
+
+This chip also has fan controlling features, using either DC or PWM, in
+three different modes (one manual, two automatic). The driver doesn't
+support these features yet.
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
+range is thus from 0 to 2.040 V. Voltage values outside of this range
+need external resistors. An exception is in0, which is used to monitor
+the chip's own power source (+3.3V), and is divided internally by a
+factor 2.
+
+The two LSB of the voltage limit registers are not used (always 0), so
+you can only set the limits in steps of 32 mV (before scaling).
+
+The wirings and resistor values suggested by Fintek are as follow:
+
+ pin expected

+(1) Depends on your hardware setup.
+(2) Obviously not correct, swapping R1 and R2 would make more sense.
+
+These values can be used as hints at best, as motherboard manufacturers
+are free to use a completely different setup. As a matter of fact, the
+Jetway K8M8MS uses a significantly different setup. You will have to
+find out documentation about your own motherboard, and edit sensors.conf
+accordingly.
+
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported as 12-bit values from a gated clock
+signal. Speeds down to 366 RPM can be measured. There is no theoretical
+high limit, but values over 6000 RPM seem to cause problem. The effective
+resolution is much lower than you would expect, the step between different
+register values being 10 rather than 1.
+
+The chip assumes 2 pulse-per-revolution fans.
+
+An alarm is triggered if the rotation speed drops below a programmable
+limit or is too low to be measured.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in degrees Celsius. Each temperature measured
+has a high limit, those crossing triggers an alarm. There is an associated
+hysteresis value, below which the temperature has to drop before the
+alarm is cleared.
+
+All temperature channels are external, there is no embedded temperature
+sensor. Each channel can be used for connecting either a thermal diode
+or a thermistor. The driver reports the currently selected mode, but
+doesn't allow changing it. In theory, the BIOS should have configured
+everything properly.

Subject: [PATCH 0216/1267] [PATCH] hwmon: New f71805f driver
This is my f71805f hardware monitoring driver ported from lm_sensors
to Linux 2.6. This new driver differs from the other hardware monitoring
drivers in that it is implemented as a platform driver. This might not
be optimal yet (we would probably need a generic infrastructure and bus
type for Super-I/O logical devices) but it is certainly much better than
the i2c-isa solution.
Note that this driver requires lm_sensors CVS. I hope to get it
released as 2.10.0 soon.

Subject: [PATCH 0217/1267] [PATCH] hwmon: Fix reboot on it87 driver load
Only scan I2C address 0x2d. This is the default address and no IT87xxF
chip was ever seen on I2C at a different address. These chips are
better accessed through their ISA interface anyway.
This fixes bug #5889, although it doesn't address the whole class
of problems. We'd need the ability to blacklist arbitrary I2C addresses
on systems known to contain I2C devices which behave badly when probed.
Plan the I2C interface for removal as well. If nobody complains within
a year, it will confirm my impression that the I2C interface isn't
actually needed by anyone.

kobject_get_path() will oops if one of the component names is
NULL. Fix that by returning NULL instead of oopsing.

Current drm code doesn't work with userspace programs that listen only

interface. Turns out lots of code can just be deleted as the driver
core can do all of this work automatically for you.

This resolves some minor version skew glitches that accumulated for the AVR
Butterfly adapter driver, which caused among other things the existence of
a duplicate Kconfig entry. Most of it boils down to comment updates, but in
one case it removes some now-superfluous code that would be better if not
copied into other controller-level drivers.

Subject: [PATCH 0234/1267] [PATCH] sky2: set mac address fix
Using the sky2 driver with bonding can result in oopses related to
reinitializing the PHY when the MAC address is changed (which bonding
is wont to do). This patch changes sky2_set_mac_address to take less
drastic measures.
This is analagous to the skge patch here:
http://lkml.org/lkml/2005/9/29/399
which fixed the issue here:

Subject: [PATCH 0256/1267] V4L/DVB (3313): FIX: Check if FW was downloaded or
not + new firmware file
- When a firmware was downloaded dvb_usb_device_init returns NULL for the
dvb_usb_device, then nothing should be done with that pointer and device,
because it will re-enumerate.
- A new firmware should be used with digitv devices.
- It should make "slave"-devices work and others, too.

Subject: [PATCH 0259/1267] V4L/DVB (3318e): DVB: remove the at76c651/tda80xx
frontends
The at76c651 and tda80xx frontends are currently completely unused, IOW
their only effect is making the kernel larger for people accitentially
enabling them.
The current in-kernel drivers differ from the drivers at cvs.tuxbox.org,
and re-adding them when parts of the dbox2 project get merged should be
trivial.

Subject: [PATCH 0265/1267] [PATCH] powerpc: Don't allocate zero bytes in
finish_device_tree()
In prom.c we run finish_node() on allnodes twice. The first time we just
calculate how much memory we'll need, the second time we do the actual work.
If the calculation stage determines that we need 0 bytes, then we should skip
the lmb allocation. Although an alloc of zero will work, it has been seen to
lead to a BUG_ON() in reserve_bootmem() on at least one machine.

To prevent problems later in boot, make sure we don't create zero-size lmb

All callers use a constant size, or they check the computed size before they

Subject: [PATCH 0267/1267] [PATCH] powerpc: Refuse to boot a kdump kernel via
OF
You can't boot a kdump kernel via OF, not reliably anyway, the kernel being at
32 MB conflicts with the zImage wrapper etc. and it blows up.
It's trivial to check in prom_init though, and this is early enough that we can
actually drop back to OF where a reset-all will get you going again, which is
kinda nice. I think this should go in for 2.6.16.

Subject: [PATCH 0268/1267] [PATCH] powerpc: IOMMU SG paranoia
This addresses two items, which are unlikely to be hit if we
trust drivers.
The first is moving a memory barrier below where the vmerged SG count
is passed back, but before the list is set to end. If those
instructions were reordered, there could be an issue in iommu_unmap_sg().
The second is making sure we terminate the list on the failure case of
iommu_map_sg(). If a driver does not look at the failure return code,
it could pass a ill-formed SG list to iommu_unmap_sg().

touch_softlockup_watchdog
It turns out that we can't stop the watchdog from
triggering here. If we touch the timer (which just uses the current jiffie
value) before we enable interrupts, it does nothing because jiffies
are not mass-updated until after we enable interrupts. If we touch the
timer after we enable interrupts, its too late because the softlockup
watchdog will already have triggered. The touch_softlockup_watchdog
call removed below does nothing.

Subject: [PATCH 0273/1267] [PATCH] powerpc: Don't overwrite flat device tree
with kdump kernel
It's possible for prom_init to allocate the flat device tree inside the
kdump crash kernel region. If this happens, when we load the kdump kernel we
overwrite the flattened device tree, which is bad.
We could make prom_init try and avoid allocating inside the crash kernel
region, but then we run into issues if the crash kernel region uses all the
space inside the RMO. The easiest solution is to move the flat device tree
once we're running in the kernel.

Subject: [PATCH 0280/1267] [PATCH] powerpc: Cleanup, consolidating icache
dirtying logic
The code to mark a page as icache dirty (so that it will later be
icache-dcache flushed when we try to execute from it) is duplicated in
three places: flush_dcache_page() does this marking and nothing else,
but clear_user_page() and copy_user_page() duplicate it, since those
functions make the page icache dirty themselves.
This patch makes those other functions call flush_dcache_page()
instead, so the logic's all in one place. This will make life less
confusing if we ever need to tweak the details of the the lazy icache
flush mechanism.

Since 404849bbd2bfd62e05b36f4753f6e1af6050a824 we've been using
LOAD_REG_ADDRBASE, which uses the toc pointer, in decrementer_iSeries_masked.
This can explode if we take the decrementer interrupt while we're in a module,
because the toc pointer in r2 will be the module's toc pointer.

effect when onlining cpu
When a cpu is hotplug-onlined, if we don't set per_cpu(last_jiffy) to
something sane, timer_interrupt will execute its while loop for every
tick missed since the cpu was last online (or since the system was
booted, if we're adding a new cpu). This can cause weird hangs, ssh
sessions dropping, and we can even go xmon if we take a global IPI at
the wrong time.

Subject: [PATCH 0300/1267] [MIPS] Au1xx0: really set KSEG0 to uncached on
reboot
Fix a really old buglet in AMD Au1xx0 restart code: instead of
modifying the whole CP0 Config.K0 field to 010b (meaning KSEG0 uncached)
before flushing the caches and resetting a board, it only sets bit 1 of that
reg. which is effectively a NOP since Config.K0 == 011b as the kernel sets it
up (which is also its default value for Au1xx0).

Subject: [PATCH 0309/1267] [MIPS] Remove commented out code to add -mmad for
Nevada.
Adding -mmad is not usable since over half a decade in gcc and when
fixed the proper -march option values should enable the use of the
mad, madu and mul instructions of the R5500, RM5200, RM7000 and RM9000
families.

Subject: [PATCH 0313/1267] [MIPS] ieee754[sd]p_neg workaround
It looks glibc's pow() assumes an unary '-' operation for any number
(including NaNs) always inverts its sign bit (though IEEE754 does not
specify the sign bit for NaNs). This patch make the kernel math-emu
emulates real MIPS neg.[ds] instruction.

Subject: [PATCH 0314/1267] [MIPS] IP22: Fix serial console detection
From: Kaj-Michael Lang <milang@tal.org>
In ip22-setup.c the checks for serial/graphics console logic does
not check if ARCS console=g but the machine is using serial console, as
it does if no keyboard is attached.
This patch adds a check if ConsoleOut is serial. There might also be
support for other graphics than Newport soon...

Subject: [PATCH 0315/1267] [MIPS] Support /proc/kcore for MIPS
I'm pretty sure that the CKSEG0 bits are wrong, but I did need to
cover that region - because the SB-1 kernel links at 0xffffffff80100000
or so, disassembly and printing static variables don't work unless the
debugger can read that region.

Very much to my surprise Fuxin Zhang reports this is all it takes to get
the kernel to work for page sizes larger than 4kB. This also paves the
way for support for the R6000 and R8000 which don't support 4kB page size.

Subject: [PATCH 0324/1267] [MIPS] TX49 MFC0 bug workaround
If mfc0 $12 follows store and the mfc0 is last instruction of a

of the mfc0 might wrongly contain EXL bit.
ERT-TX49H2-027, ERT-TX49H3-012, ERT-TX49HL3-006, ERT-TX49H4-008
Workaround: mask EXL bit of the result or place a nop before mfc0. It
doesn't harm to always clear those bits, so we change the code to do so.

Subject: [PATCH 0325/1267] [MIPS] TX49x7: Fix reporting of the CPU name and
PCI clock
I've noticed that PCI clock was incorrectly reported as 66 MHz while being
mere 33 MHz on RBTX4937 board -- this was due to the different encoding of
the PCI divisor field in CCFG register between TX4927 and TX4937 chips...
Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937");
and some debug printk() were duplicating each other...

Subject: [PATCH 0334/1267] [IA64] Fix wrong use of memparse in efi.c
The check of (end != cp) after memparse in efi.c looks wrong to me.
The result is that we can't use mem= and max_addr= kernel parameter at
the same time.
The following patch removed the check just like other arches do.

Subject: [PATCH 0335/1267] [IA64] Fix CONFIG_PRINTK_TIME
There were two problems with enabling the PRINTK_TIME config
option:
1) The first calls to printk() occur before per-cpu data virtual
address is pinned into the TLB, so sched_clock() can fault.
2) sched_clock() is based on ar.itc, which may not be synchronized
across cpus.
Ken Chen started this patch, Tony Luck tinkered with it, and Jes
Sorensen perfected it.

Subject: [PATCH 0338/1267] [PATCH] x86_64: Fix the node cpumask of a cpu going
down
Currently, x86_64 and ia64 arches do not clear the corresponding bits in
the node's cpumask when a cpu goes down or cpu bring up is cancelled. This
is buggy since there are pieces of common code where the cpumask is checked
in the cpu down code path to decide on things (like in the slab down path).
PPC does the right thing, but x86_64 and ia64 don't (This was the reason
Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce
on other arches). This patch fixes it for x86_64. I won't attempt ia64 as
I cannot test it.
Credit for spotting this should go to Alok.
(akpm: this was applied, then reverted. But it's OK now because we now use
for_each_cpu() in the right places).

When hugepages are newly allocated to a file in mm/hugetlb.c, we clear them
with a call to clear_highpage() on each of the subpages. We should be
using clear_user_highpage(): on powerpc, at least, clear_highpage() doesn't
correctly mark the page as icache dirty so if the page is executed shortly
after it's possible to get strange results.

This does not show up unless you #define DEBUG in the file, which most
people wouldn't do. On PPC405, at least, "sector_t" is unsigned long,
which doesn't match %llx/%llu. Since sector# may well be >32 bits, promote
the value to match the format.

Subject: [PATCH 0343/1267] [PATCH] __cmpxchg() must really always be inlined
on alpha
With the latest 2.6.15 kernel builds for alpha on Debian, we ran into a
problem with undefined references to __cmpxchg_called_with_bad_pointer() in
a couple of kernel modules (xfs.ko and drm.ko; see
http://bugs.debian.org/347556).
It looks like people have been trying to out-clever each other wrt the
definition of "inline" on this architecture :), with the result that
__cmpxchg(), which must be inlined so the compiler can see its argument is
const, is not guaranteed to be inlined. Indeed, it was not being inlined
when building with -Os.
The attached patch fixes the issue by adding an
__attribute__((always_inline)) explicitly to the definition of __cmpxchg()
instead of relying on redefines of "inline" elsewhere to make this happen.

It doesn't do anything but emit a warning, but there's a user population
that's used to adding 'debug' to the UML command line in order to gdb it.
With skas0 mode, that's not necessary, but these users need some indication
that 'debug' doesn't do what they want.

Subject: [PATCH 0346/1267] [PATCH] uml: close TUN/TAP file descriptors
When UML opens a TUN/TAP device, the file descriptor could be copied into
later, long-lived threads, holding the device open even after the interface is
taken down, preventing it from being brought up again. This patch makes these
descriptors close-on-exec so that they disappear from helper processes, and
adds CLONE_FILES to a UML helper thread so that the descriptors are closed in
the thread when they are closed elsewhere in UML.

Subject: [PATCH 0347/1267] [PATCH] uml: balance list_add and list_del in the
network driver
The network driver added an interface to the "opened" list when it was
configured, not when it was brought up, and removed it when it was taken down.
A sequence of ifconfig up, ifconfig down, ... caused it to be removed
multiple times from the list without being added in between, resulting in a
crash. This patch moves the add to when the interface is brought up.

Subject: [PATCH 0353/1267] [PATCH] sys_hpux: fix strlen_user() race
Userspace can alter the string after the kernel has run strlen_user().
Also: the strlen_user() return value includes the \0, so fix that.
Also: handle EFAULT from strlen_user().
It's unlikely anyone is using this code. Very, very unlikely. If I
remember correctly, CONFIG_HPUX turns this code on, but one would actually
need CONFIG_BINFMT_SOM to load a binary that could cause a problem, and
BINFMT_SOM has had an #error in it for quite some time.

Subject: [PATCH 0357/1267] [PATCH] mm: compound release fix
Compound pages on SMP systems can now often be freed from pagetables via
the release_pages path. This uses put_page_testzero which does not handle
compound pages at all. Releasing constituent pages from process mappings
decrements their count to a large negative number and leaks the reference
at the head page - net result is a memory leak.
The problem was hidden because the debug check in put_page_testzero itself
actually did take compound pages into consideration.
Fix the bug and the debug check.

Subject: [PATCH 0358/1267] [PATCH] Fix spinlock debugging delays to not time
out too early
The spinlock-debug wait-loop was using loops_per_jiffy to detect too long
spinlock waits - but on fast CPUs this led to a way too fast timeout and false
messages.
The fix is to include a __delay(1) call in the loop, to correctly approximate
the intended delay timeout of 1 second. The code assumes that every
architecture implements __delay(1) to last around 1/(loops_per_jiffy*HZ)
seconds.

+--------------------
+This document describes the new system call, unshare. The document
+provides an overview of the feature, why it is needed, how it can
+be used, its interface specification, design, implementation and
+how it can be tested.
+
+Change Log:
+-----------
+version 0.1 Initial document, Janak Desai (janak@us.ibm.com), Jan 11, 2006
+
+Contents:
+---------
+ 1) Overview
+ 2) Benefits
+ 3) Cost
+ 4) Requirements
+ 5) Functional Specification
+ 6) High Level Design
+ 7) Low Level Design
+ 8) Test Specification
+ 9) Future Work
+
+1) Overview
+-----------
+Most legacy operating system kernels support an abstraction of threads
+as multiple execution contexts within a process. These kernels provide
+special resources and mechanisms to maintain these "threads". The Linux
+kernel, in a clever and simple manner, does not make distinction
+between processes and "threads". The kernel allows processes to share
+resources and thus they can achieve legacy "threads" behavior without
+requiring additional data structures and mechanisms in the kernel. The
+power of implementing threads in this manner comes not only from
+its simplicity but also from allowing application programmers to work
+outside the confinement of all-or-nothing shared resources of legacy
+threads. On Linux, at the time of thread creation using the clone system
+call, applications can selectively choose which resources to share
+between threads.
+
+unshare system call adds a primitive to the Linux thread model that
+allows threads to selectively 'unshare' any resources that were being
+shared at the time of their creation. unshare was conceptualized by
+Al Viro in the August of 2000, on the Linux-Kernel mailing list, as part
+of the discussion on POSIX threads on Linux. unshare augments the
+usefulness of Linux threads for applications that would like to control
+shared resources without creating a new process. unshare is a natural
+addition to the set of available primitives on Linux that implement
+the concept of process/thread as a virtual machine.
+
+2) Benefits
+-----------
+unshare would be useful to large application frameworks such as PAM
+where creating a new process to control sharing/unsharing of process
+resources is not possible. Since namespaces are shared by default
+when creating a new process using fork or clone, unshare can benefit
+even non-threaded applications if they have a need to disassociate
+from default shared namespace. The following lists two use-cases
+where unshare can be used.
+
+2.1 Per-security context namespaces
+-----------------------------------
+unshare can be used to implement polyinstantiated directories using
+the kernel's per-process namespace mechanism. Polyinstantiated directories,
+such as per-user and/or per-security context instance of /tmp, /var/tmp or
+per-security context instance of a user's home directory, isolate user
+processes when working with these directories. Using unshare, a PAM
+module can easily setup a private namespace for a user at login.
+Polyinstantiated directories are required for Common Criteria certification
+with Labeled System Protection Profile, however, with the availability
+of shared-tree feature in the Linux kernel, even regular Linux systems
+can benefit from setting up private namespaces at login and
+polyinstantiating /tmp, /var/tmp and other directories deemed
+appropriate by system administrators.
+
+2.2 unsharing of virtual memory and/or open files
+-------------------------------------------------
+Consider a client/server application where the server is processing
+client requests by creating processes that share resources such as
+virtual memory and open files. Without unshare, the server has to
+decide what needs to be shared at the time of creating the process
+which services the request. unshare allows the server an ability to
+disassociate parts of the context during the servicing of the
+request. For large and complex middleware application frameworks, this
+ability to unshare after the process was created can be very
+useful.
+
+3) Cost
+-------
+In order to not duplicate code and to handle the fact that unshare
+works on an active task (as opposed to clone/fork working on a newly
+allocated inactive task) unshare had to make minor reorganizational
+changes to copy_* functions utilized by clone/fork system call.
+There is a cost associated with altering existing, well tested and
+stable code to implement a new feature that may not get exercised
+extensively in the beginning. However, with proper design and code
+review of the changes and creation of an unshare test for the LTP
+the benefits of this new feature can exceed its cost.
+
+4) Requirements
+---------------
+unshare reverses sharing that was done using clone(2) system call,
+so unshare should have a similar interface as clone(2). That is,
+since flags in clone(int flags, void *stack) specifies what should
+be shared, similar flags in unshare(int flags) should specify
+what should be unshared. Unfortunately, this may appear to invert
+the meaning of the flags from the way they are used in clone(2).
+However, there was no easy solution that was less confusing and that
+allowed incremental context unsharing in future without an ABI change.
+
+unshare interface should accommodate possible future addition of
+new context flags without requiring a rebuild of old applications.
+If and when new context flags are added, unshare design should allow
+incremental unsharing of those resources on an as needed basis.
+
+5) Functional Specification
+---------------------------
+NAME
+ unshare - disassociate parts of the process execution context
+
+SYNOPSIS
+ #include <sched.h>
+
+ int unshare(int flags);
+
+DESCRIPTION
+ unshare allows a process to disassociate parts of its execution
+ context that are currently being shared with other processes. Part
+ of execution context, such as the namespace, is shared by default
+ when a new process is created using fork(2), while other parts,
+ such as the virtual memory, open file descriptors, etc, may be
+ shared by explicit request to share them when creating a process
+ using clone(2).
+
+ The main use of unshare is to allow a process to control its
+ shared execution context without creating a new process.
+
+ The flags argument specifies one or bitwise-or'ed of several of
+ the following constants.
+
+ CLONE_FS
+ If CLONE_FS is set, file system information of the caller
+ is disassociated from the shared file system information.
+
+ CLONE_FILES
+ If CLONE_FILES is set, the file descriptor table of the
+ caller is disassociated from the shared file descriptor
+ table.
+
+ CLONE_NEWNS
+ If CLONE_NEWNS is set, the namespace of the caller is
+ disassociated from the shared namespace.
+
+ CLONE_VM
+ If CLONE_VM is set, the virtual memory of the caller is
+ disassociated from the shared virtual memory.
+
+RETURN VALUE
+ On success, zero returned. On failure, -1 is returned and errno is
+
+ERRORS
+ EPERM CLONE_NEWNS was specified by a non-root process (process
+ without CAP_SYS_ADMIN).
+
+ ENOMEM Cannot allocate sufficient memory to copy parts of caller's

+
+ EINVAL Invalid flag was specified as an argument.
+
+CONFORMING TO
+ The unshare() call is Linux-specific and should not be used
+ in programs intended to be portable.
+
+SEE ALSO
+ clone(2), fork(2)
+
+6) High Level Design
+--------------------
+Depending on the flags argument, the unshare system call allocates
+appropriate process context structures, populates it with values from
+the current shared version, associates newly duplicated structures
+with the current task structure and releases corresponding shared
+versions. Helper functions of clone (copy_*) could not be used
+directly by unshare because of the following two reasons.
+ 1) clone operates on a newly allocated not-yet-active task
+ structure, where as unshare operates on the current active
+ task. Therefore unshare has to take appropriate task_lock()
+ before associating newly duplicated context structures
+ 2) unshare has to allocate and duplicate all context structures
+ that are being unshared, before associating them with the
+ current task and releasing older shared structures. Failure
+ do so will create race conditions and/or oops when trying
+ to backout due to an error. Consider the case of unsharing
+ both virtual memory and namespace. After successfully unsharing
+ vm, if the system call encounters an error while allocating
+ new namespace structure, the error return code will have to
+ reverse the unsharing of vm. As part of the reversal the
+ system call will have to go back to older, shared, vm
+ structure, which may not exist anymore.
+
+Therefore code from copy_* functions that allocated and duplicated
+current context structure was moved into new dup_* functions. Now,
+copy_* functions call dup_* functions to allocate and duplicate
+appropriate context structures and then associate them with the
+task structure that is being constructed. unshare system call on
+the other hand performs the following:
+ 1) Check flags to force missing, but implied, flags
+ 2) For each context structure, call the corresponding unshare
+ helper function to allocate and duplicate a new context
+ structure, if the appropriate bit is set in the flags argument.
+ 3) If there is no error in allocation and duplication and there
+ are new context structures then lock the current task structure,
+ associate new context structures with the current task structure,
+ and release the lock on the current task structure.
+ 4) Appropriately release older, shared, context structures.
+
+7) Low Level Design
+-------------------
+Implementation of unshare can be grouped in the following 4 different
+items:
+ a) Reorganization of existing copy_* functions
+ b) unshare system call service function
+ c) unshare helper functions for each different process context
+ d) Registration of system call number for different architectures
+
+ 7.1) Reorganization of copy_* functions
+ Each copy function such as copy_mm, copy_namespace, copy_files,
+ etc, had roughly two components. The first component allocated
+ and duplicated the appropriate structure and the second component
+ linked it to the task structure passed in as an argument to the copy
+ function. The first component was split into its own function.
+ These dup_* functions allocated and duplicated the appropriate
+ context structure. The reorganized copy_* functions invoked
+ their corresponding dup_* functions and then linked the newly
+ duplicated structures to the task structure with which the
+ copy function was called.
+
+ 7.2) unshare system call service function
+ * Check flags
+ Force implied flags. If CLONE_THREAD is set force CLONE_VM.
+ If CLONE_VM is set, force CLONE_SIGHAND. If CLONE_SIGHAND is
+ set and signals are also being shared, force CLONE_THREAD. If
+ CLONE_NEWNS is set, force CLONE_FS.
+ * For each context flag, invoke the corresponding unshare_*
+ helper routine with flags passed into the system call and a
+ reference to pointer pointing the new unshared structure
+ * If any new structures are created by unshare_* helper
+ functions, take the task_lock() on the current task,
+ modify appropriate context pointers, and release the
+ task lock.
+ * For all newly unshared structures, release the corresponding
+ older, shared, structures.
+
+ 7.3) unshare_* helper functions
+ For unshare_* helpers corresponding to CLONE_SYSVSEM, CLONE_SIGHAND,
+ and CLONE_THREAD, return -EINVAL since they are not implemented yet.
+ For others, check the flag value to see if the unsharing is
+ required for that structure. If it is, invoke the corresponding
+ dup_* function to allocate and duplicate the structure and return
+ a pointer to it.
+
+ 7.4) Appropriately modify architecture specific code to register the
+ the new system call.
+
+8) Test Specification
+---------------------
+The test for unshare should test the following:
+ 1) Valid flags: Test to check that clone flags for signal and
+ signal handlers, for which unsharing is not implemented
+ yet, return -EINVAL.
+ 2) Missing/implied flags: Test to make sure that if unsharing
+ namespace without specifying unsharing of filesystem, correctly
+ unshares both namespace and filesystem information.
+ 3) For each of the four (namespace, filesystem, files and vm)
+ supported unsharing, verify that the system call correctly
+ unshares the appropriate structure. Verify that unsharing
+ them individually as well as in combination with each
+ other works as expected.
+ 4) Concurrent execution: Use shared memory segments and futex on
+ an address in the shm segment to synchronize execution of
+ about 10 threads. Have a couple of threads execute execve,
+ a couple _exit and the rest unshare with different combination
+ of flags. Verify that unsharing is performed as expected and
+ that there are no oops or hangs.
+
+9) Future Work
+--------------
+The current implementation of unshare does not allow unsharing of
+signals and signal handlers. Signals are complex to begin with and
+to unshare signals and/or signal handlers of a currently running
+process is even more complex. If in the future there is a specific
+need to allow unsharing of signals and/or signal handlers, it can
+be incrementally added to unshare without affecting legacy
+applications using unshare.

Subject: [PATCH 0360/1267] [PATCH] unshare system call -v5: system call
handler function
sys_unshare system call handler function accepts the same flags as clone
system call, checks constraints on each of the flags and invokes corresponding
unshare functions to disassociate respective process context if it was being
shared with another task.
Here is the link to a program for testing unshare system call.
http://prdownloads.sourceforge.net/audit/unshare_test.c?download
Please note that because of a problem in rmdir associated with bind mounts and
clone with CLONE_NEWNS, the test fails while trying to remove temporary test
directory. You can remove that temporary directory by doing rmdir, twice,
from the command line. The first will fail with EBUSY, but the second will
succeed. I have reported the problem to Ram Pai and Al Viro with a small
program which reproduces the problem. Al told us yesterday that he will be
looking at the problem soon. I have tried multiple rmdirs from the
unshare_test program itself, but for some reason that is not working. Doing
two rmdirs from command line does seem to remove the directory.

Subject: [PATCH 0371/1267] IPoIB: Don't start send-only joins while multicast
thread is stopped
Fix the following race scenario:
- Device is up.
- Port event or set mcast list triggers ipoib_mcast_stop_thread,
this cancels the query and waits on mcast "done" completion.
- Completion is called and "done" is set.
- Meanwhile, ipoib_mcast_send arrives and starts a new query,
re-initializing "done".
Fix this by adding a "multicast started" bit and checking it before
starting a send-only join.

Subject: [PATCH 0372/1267] IPoIB: Fix another send-only join race
Further, there's an additional issue that I saw in testing:
ipoib_mcast_send may get called when priv->broadcast is NULL (e.g. if
the device was downed and then upped internally because of a port
event).
If this happends and the send-only join request gets completed before
priv->broadcast is set, we get an oops.

Subject: [PATCH 0400/1267] [PATCH] nfsroot port= parameter fix [backport of
2.4 fix]
Direct backport of 2.4 fix that didn't get propagated to 2.6; original
comment follows:
<quote>
When I specify the NFS port for nfsroot (e.g.,
nfsroot=<dir>,port=2049), the
kernel uses the wrong port. In my case it tries to use 264 (0x108)
instead
of 2049 (0x801).
This patch adds the missing htons().
Eric
</quote>
Patch got applied in 2.4.21-pre6. Author: Eric Lammerts (<eric@lammerts.org>,
AFAICS).

Subject: [PATCH 0404/1267] [PATCH] powerpc: Fix sound driver use of i2c
The PowerMac sound drivers used to rely on a "bug" of the i2c-keywest
driver that implemented I2C_SMBUS_BLOCK_DATA incorrectly, that is it did
what I2C_SMBUS_I2C_BLOCK_DATA should have done. The new i2c-powermac
driver that replaces keywest has this bug fixed, thus the sound drivers
must be fixed too.

Subject: [PATCH 0405/1267] [PATCH] arm: fix dependencies for MTD_XIP
MTD_XIP depends on having working asm/mtd-xip.h; it's not just per-architecture
(arm-only, as current Kconfig would have it), but actually per-subarch as
well. Introduced a new symbol (ARCH_MTD_XIP) set by arch Kconfig; MTD_XIP
depends on it.

fixes
* compat_alloc_user_space() returns __user pointer
* copying between two userland areas is copy_in_user(), not copy_from_user()
* dereferencing userland pointers is bad

Subject: [PATCH 0418/1267] [PATCH] powerpc: Thermal control for dual core G5s
This patch adds a windfarm module, windfarm_pm112, for the dual core G5s
(both 2 and 4 core models), keeping the machine from getting into
vacuum-cleaner mode ;) For proper credits, the patch was initially
written by Paul Mackerras, and slightly reworked by me to add overtemp
handling among others. The patch also removes the sysfs attributes from
windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm
core to automagically expose attributes for sensor & controls.

When issuing an SG_IO ioctl through sd that resulted in an unrecoverable
error, a nearly infinite retry loop was discovered. This is due to the
fact that the block layer SG_IO code is not setting up rq->retries. This
patch also fixes up the sg_scsi_ioctl path.

Subject: [PATCH 0425/1267] [PATCH] block: implement elv_insert and use it (fix
ordcolor flipping bug)
q->ordcolor must only be flipped on initial queueing of a hardbarrier
request.
Constructing ordered sequence and requeueing used to pass through
__elv_add_request() which flips q->ordcolor when it sees a barrier
request.
This patch separates out elv_insert() from __elv_add_request() and uses
elv_insert() when constructing ordered sequence and requeueing.
elv_insert() inserts the given request at the specified position and
does nothing else.

Subject: [PATCH 0427/1267] [PATCH] alpha: set cpu_possible_map much earlier
All the percpu data structure walkers want cpu_possible_map to be
initialized early, but alpha instead populated "hwrpb_cpu_present_mask"
early in setup_smp(), and then initialized cpu_possible_map only much
later.
Thanks go to Heiko Carstens and Dipankar Sarma for noticing.
This fixes it and we can get rid of hwrpb_cpu_present_mask entirely.

The ixdp2x01 pci init call doesn't check whether it's really running
on an ixdp2x01, making it impossible to compile one kernel that works
on both the ixdp2x01 and another ixp2000 board.

The ixdp2x01_clock is already 50MHz by default, so no need to
override it with 50MHz in the ixdp2801 defconfig as is done now,
which is confusing as well.

Patch from Lennert Buytenhek
Most ixp2000 boards don't actually work if pci=firmware isn't used, so
the defconfig isn't really the right place to specify this. Instead of
specifying it in the defconfigs, make the relevant board code take care
of setting pci=firmware.

Subject: [PATCH 0437/1267] [ARM] 3303/1: S3C24XX - add clock enable usage
counting
Patch from Ben Dooks
Move to using an enable count for the shared clocks
and protect the clock system using a mutex instead
of just disabling IRQs during the clock update.
Since there is little more code in the path for
non-shared clocks, the enable and disable calls
use the same code for each.

struct sockaddr_un loses its padding with EABI. Since the size of the
structure is used as a validation test in unix_mkname(), we need to
change the length argument to 110 whenever it is 112.

Subject: [PATCH 0444/1267] [ARM] 3309/1: disable the pre-ARMv5 NPTL kernel
helper in the non MMU case
Patch from Nicolas Pitre
The cmpxchg emulation on pre-ARMv5 relies on user code executed from a
kernel address. If the operation cannot complete atomically, it is
aborted from the usr_entry macro by clearing the Z flag. This clearing
of the Z flag is done whenever the user pc is above TASK_SIZE.
However this "pc >= TASK_SIZE" test cannot work in the non MMU case.
Worse: the current code will corrupt the Z flag on every entry to the
kernel.
Let's disable it in the non MMU case for now. Using NPTL on non MMU
targets needs to be worked out anyway.

__kuser_cmpxchg transient false negative
Patch from Nicolas Pitre
The pre ARMv5 implementation can be aborted if an exception occurs in
the middle of it. Because of that, the ARMv6 implementation doesn't
re-attempt the operation on a failed strex either. Let's make this
transient nature of such a false positive more explicit in the
definition.

Subject: [PATCH 0446/1267] [ARM] 3311/1: clean up include/asm-arm/mutex.h
Patch from Nicolas Pitre
Since:
if (unlikely(__res || __ex_flag))
produces worse code on ARM than:
if (unlikely(__res | __ex_flag))
I therefore made it more explicit:
__res |= __ex_flag;
if (unlikely(__res != 0))
so it is not seen as a typo again.
Also made everything static inline rather than macros for better readability
(both produce the same code after all).
And finally added missing \t from multi-line assembly code.

serial8250_console_write() was updating the IER in hardware without
also updating the copy in uart_8250_port. This causes issues functions

Subject: [PATCH 0455/1267] [ARM] 3279/1: OMAP: 1/3 Fix low-level io init
Patch from Tony Lindgren
This patch adds the missing cache flushes to common low-level
init that are needed to access the IO region. These flushes
are normally done at the end of devicemaps_init(), but we
need to detect the OMAP core type early.

Subject: [PATCH 0461/1267] [IPV6]: Address autoconfiguration does not work
after device down/up cycle
If you set network interface down and up again, the IPv6 address
autoconfiguration does not work. 'ip addr' shows that the link-local
address is in tentative state. We don't even react to periodical router
advertisements.
During NETDEV_DOWN we clear IF_READY, and we don't set it back in
NETDEV_UP. While starting to perform DAD on the link-local address, we
notice that the device is not in IF_READY, and we abort autoconfiguration
process (which would eventually send router solicitations).

Subject: [PATCH 0474/1267] [NETLINK]: Fix a severe bug
netlink overrun was broken while improvement of netlink.
Destination socket is used in the place where it was meant to be source socket,
so that now overrun is never sent to user netlink sockets, when it should be,
and it even can be set on kernel socket, which results in complete deadlock
of rtnetlink.
Suggested fix is to restore status quo passing source socket as additional
argument to netlink_attachskb().
A little explanation: overrun is set on a socket, when it failed
to receive some message and sender of this messages does not or even
have no way to handle this error. This happens in two cases:
1. when kernel sends something. Kernel never retransmits and cannot
wait for buffer space.
2. when user sends a broadcast and the message was not delivered
to some recipients.

Subject: [PATCH 0475/1267] [NETLINK]: illegal use of pid in rtnetlink
When a netlink message is not related to a netlink socket,
it is issued by kernel socket with pid 0. Netlink "pid" has nothing
to do with current->pid. I called it incorrectly, if it was named "port",
the confusion would be avoided.

Subject: [PATCH 0481/1267] [BRIDGE]: fix error handling for add interface to
bridge
Refactor how the bridge code interacts with kobject system.
It should still use kobjects even if not using sysfs.
Fix the error unwind handling in br_add_if.

arch/powerpc/kernel/systbl.S
With this, new system calls only have to be wired up in one place
for ARCH=ppc and ARCH=powerpc, rather than 2.

+ f) Freescale SOC USB controllers
+
+ The device node for a USB controller that is part of a Freescale
+ SOC is as described in the document "Open Firmware Recommended
+ Practice : Universal Serial Bus" with the following modifications
+ and additions :
+
+ Required properties :
+ - compatible : Should be "fsl-usb2-mph" for multi port host usb
+ controllers, or "fsl-usb2-dr" for dual role usb controllers
+ - phy_type : For multi port host usb controllers, should be one of
+ "ulpi", or "serial". For dual role usb controllers, should be
+ one of "ulpi", "utmi", "utmi_wide", or "serial".
+ - reg : Offset and length of the register set for the device
+ - port0 : boolean; if defined, indicates port0 is connected for
+ fsl-usb2-mph compatible controllers. Either this property or
+ "port1" (or both) must be defined for "fsl-usb2-mph" compatible
+ controllers.
+ - port1 : boolean; if defined, indicates port1 is connected for
+ fsl-usb2-mph compatible controllers. Either this property or
+ "port0" (or both) must be defined for "fsl-usb2-mph" compatible
+ controllers.
+
+ Recommended properties :
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+ Example multi port host usb controller device node :
+ usb@22000 {
+ device_type = "usb";
+ compatible = "fsl-usb2-mph";
+ reg = <22000 1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = <700>;
+ interrupts = <27 1>;
+ phy_type = "ulpi";
+ port0;
+ port1;
+ };
+
+ Example dual role usb controller device node :
+ usb@23000 {
+ device_type = "usb";
+ compatible = "fsl-usb2-dr";
+ reg = <23000 1000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = <700>;
+ interrupts = <26 1>;
+ phy = "ulpi";
+ };
+
+
More devices will be defined as this spec matures.

Subject: [PATCH 0486/1267] [PATCH] sched: remove smpnice
I don't think the code is quite ready, which is why I asked for Peter's
additions to also be merged before I acked it (although it turned out that
it still isn't quite ready with his additions either).
Basically I have had similar observations to Suresh in that it does not
play nicely with the rest of the balancing infrastructure (and raised
similar concerns in my review).
The samples (group of 4) I got for "maximum recorded imbalance" on a 2x2
SMP+HT Xeon are as follows:
| Following boot | hackbench 20 | hackbench 40
-----------+----------------+---------------------+---------------------
2.6.16-rc2 | 30,37,100,112 | 5600,5530,6020,6090 | 6390,7090,8760,8470
+nosmpnice | 3, 2, 4, 2 | 28, 150, 294, 132 | 348, 348, 294, 347
Hackbench raw performance is down around 15% with smpnice (but that in
itself isn't a huge deal because it is just a benchmark). However, the
samples show that the imbalance passed into move_tasks is increased by
about a factor of 10-30. I think this would also go some way to explaining
latency blips turning up in the balancing code (though I haven't actually
measured that).
We'll probably have to revert this in the SUSE kernel.

Subject: [PATCH 0488/1267] [PATCH] kexec: fix in free initrd when overlapped
with crashkernel region
It is possible that the reserved crashkernel region can be overlapped with
initrd since the bootloader sets the initrd location. When the initrd
region is freed, the second kernel memory will not be contiguous. The
Kexec_load can cause an oops since there is no contiguous memory to write
the second kernel or this memory could be used in the first kernel itself
and may not be part of the dump. For example, on powerpc, the initrd is
located at 36MB and the crashkernel starts at 32MB. The kexec_load caused
panic since writing into non-allocated memory (after 36MB). We could see
the similar issue even on other archs.
One possibility is to move the initrd outside of crashkernel region. But,
the initrd region will be freed anyway before the system is up. This patch
fixes this issue and frees only regions that are not part of crashkernel
memory in case overlaps.

Subject: [PATCH 0490/1267] [PATCH] Fix building external modules on ppc32
We are setting up sources for building external modules like this:
/usr/src/linux-obj> # create a .config file
/usr/src/linux-obj> make -C /usr/src/linux O=$PWD oldconfig
/usr/src/linux-obj> make -C /usr/src/linux O=$PWD prepare
/usr/src/linux-obj> make -C /usr/src/linux O=$PWD scripts
/usr/src/linux-obj> make -C /usr/src/linux O=$PWD clean
After that, external modules can be built with:
/usr/src/module> make -C /usr/src/linux-obj M=$PWD
This fails for ppc32 because the `make clean' removes the
arch/powerpc/include directory. This should be done in archmrproper
instead of in archclean.

Subject: [PATCH 0491/1267] [PATCH] x86: don't initialise cpu_possible_map to
all ones
Initialising cpu_possible_map to all-ones with CONFIG_HOTPLUG_CPU means that
a) All for_each_cpu() loops will iterate across all NR_CPUS CPUs, rather
than over possible ones. That can be quite expensive.
b) Soon we'll be allocating per-cpu areas only for possible CPUs. So with
CPU_MASK_ALL, we'll be wasting memory.
I also switched voyager over to not use CPU_MASK_ALL in the non-CPU-hotplug
case. Should be OK..
I note that parisc is also using CPU_MASK_ALL. Suggest that it stop doing
that.

Subject: [PATCH 0493/1267] [PATCH] shmdt cannot detach not-alined shm segment
cleanly.
sys_shmdt() can manage shm segments which are covered by multiple vmas. (This
can happen when a user uses mprotect() after shmat().)
This works well if shm is aligned to PAGE_SIZE, but if not, the last
segment cannot be detached. It is because a comparison in sys_shmdt()
(vma->vm_end - addr) < size
addr == return address of shmat()
size == shmsize, argments to shmget()
size should be aligned to PAGE_SIZE before being compared with vma->vm_end,
which is aligned.

Also swap_page does need to ignore all reference bits when unmapping a
page. Otherwise we may have to repeatedly unmap a frequently touched page.
So change the try_to_unmap parameter to 1.

Subject: [PATCH 0499/1267] [SERIAL] Remove incorrect code from ioc4 serial
driver
Serial drivers in general should not write uart_info->flags - they're
private to serial_core. Serial drivers have no need to fiddle with
tty->alt_speed, nor manipulate TTY_IO_ERROR in tty->flags. Fix the
ioc4 serial driver for both these points by simply removing the
offending code.

Subject: [PATCH 0501/1267] IB/mthca: Don't print debugging info until we have
all values
When debugging is enabled, the mthca_QUERY_DEV_LIM() firmware command
function prints out some of the device limits that it queries.
However the debugging prints happen before all of the fields are
extracted from the firmware response, so some of the values that get
printed are uninitialized junk. Move the prints to the end of the
function to fix this.

Subject: [PATCH 0502/1267] IPoIB: Yet another fix for send-only joins
Even after the last fix, it's still possible for a send-only join to
start before the join for the broadcast group has finished. This
could cause us to create a multicast group using attributes from the
broadcast group that haven't been initialized yet, so we would use
garbage for the Q_Key, etc. Fix this by waiting until the broadcast
group's attached flag is set before starting send-only joins.

Subject: [PATCH 0503/1267] [PATCH] fstatat64 support
The *at patches introduced fstatat and, due to inusfficient research, I
used the newfstat functions generally as the guideline. The result is that
on 32-bit platforms we don't have all the information needed to implement
fstatat64.
This patch modifies the code to pass up 64-bit information if
__ARCH_WANT_STAT64 is defined. I renamed the syscall entry point to make
this clear. Other archs will continue to use the existing code. On x86-64
the compat code is implemented using a new sys32_ function. this is what
is done for the other stat syscalls as well.
This patch might break some other archs (those which define
__ARCH_WANT_STAT64 and which already wired up the syscall). Yet others
might need changes to accomodate the compatibility mode. I really don't
want to do that work because all this stat handling is a mess (more so in
glibc, but the kernel is also affected). It should be done by the arch
maintainers. I'll provide some stand-alone test shortly. Those who are
eager could compile glibc and run 'make check' (no installation needed).
The patch below has been tested on x86 and x86-64.

Subject: [PATCH 0505/1267] [PATCH] x86-64: Fix HPET timer on x460
[description from AK]
The IBM Summit 3 chipset doesn't implement the HPET timer replacement
option. Since the current Linux code relies on it use a mixed mode with
both PIT for the interrupt and HPET counters for the time keeping. That
was already implemented, but didn't work properly because it was still
using the last interrupt offset in HPET. This resulted in x460 not
booting. Fix this up by using the free running HPET counter.
Shouldn't affect any other machine because they either use full HPET mode
or no HPET at all.
TBD needs a similar 32bit fix.

Subject: [PATCH 0506/1267] [PATCH] select: fix returned timeval
With David Woodhouse <dwmw2@infradead.org>
select() presently has a habit of increasing the value of the user's
`timeout' argument on return.
We were writing back a timeout larger than the original. We _deliberately_
round up, since we know we must wait at _least_ as long as the caller asks
us to.
The patch adds a couple of helper functions for magnitude comparison of
timespecs and of timevals, and uses them to prevent the various poll and
select functions from returning a timeout which is larger than the one which
was passed in.
The patch also fixes a bug in compat_sys_pselect7(): it was adding the new
timeout value to the old one and was returning that. It should just return
the new timeout value.
(We have various handy timespec/timeval-to-from-nsec conversion functions in
time.h. But this code open-codes it all).

page during zone reclaim
shrink_list() and refill_inactive() check all ptes pointing to a page for
reference bits in order to decide if the page should be put on the active
list. This is not necessary for zone_reclaim since we are only interested
in removing unmapped pages. Skip the checks in both functions.

Lost a few hours debugging an early-bootup fault within printk itself,
which manifested itself as a hard to debug early hang.
This patch makes it much easier by printing out early faults via
early_printk(), which function is a lot simpler than a full printk, and
hence more likely to succeed in emergencies. (We do not recover from early
faults anyway, so there's no loss from not having these messages in the
normal printk buffer.)

Subject: [PATCH 0513/1267] [PATCH] s390: fix sclp memory corruption in tty
pages list
When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface. Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list. The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.
To avoid this remove the busy retry limit and increase retry intervals.

Subject: [PATCH 0532/1267] [SCSI] ipr: Fix adapter initialization failure
Since scsi core is always sending scatterlists now, remove
some code which was written with the bad assumption that
a small transfer would not be sent down in a scatterlist.
Without this fix, the ipr driver ends up sending garbage
data to the adapter following a reset, causing it to
fail the reset and take the adapter offline.

Subject: [PATCH 0533/1267] [SCSI] megaraid_legacy: kobject_register failure
Attached patch fixes problem that cause kobject_register failure
during loading. Kobject_register would fail when there are more than
1 module with same module name. This patch will change module name of
megaraid_legacy from 'megaraid' to 'megaraid_legacy'.

pm->sg.size is set from the Residual Byte Count register. However,
the upper byte of the RBC is the opcode of the instruction that was
executing, so we need to mask it off. This fixes some spurious rejects
of IGNORE WIDE RESIDUE messages.

reiserfs inode attributes
Unfortunately, the reiserfs_attrs_cleared bit in the superblock flag can
lie. File systems have been observed with the bit set, yet still contain
garbage in the stat data field, causing unpredictable results.
This patch backs out the enable-by-default behavior.
It eliminates the changes from: d50a5cd860ce721dbeac6a4f3c6e42abcde68cd8,
and ef5e5414e7a83eb9b4295bbaba5464410b11e030.

Subject: [PATCH 0543/1267] [PATCH] arch/x86_64/kernel/traps.c
PTRACE_SINGLESTEP oops
We found a problem with x86_64 kernels with preemption enabled, where
having multiple tasks doing ptrace singlesteps around the same time will
cause the system to 'oops'. The problem seems that a task can get
preempted out of the do_debug() processing while it is running on the
DEBUG_STACK stack. If another task on that same cpu then enters do_debug()
and uses the same per-cpu DEBUG_STACK stack, the previous preempted tasks's
stack contents can be corrupted, and the system will oops when the
preempted task is context switched back in again.
The typical oops looks like the following:

This patch disables preemptions for the task upon entry to do_debug(), before
interrupts are reenabled, and then disables preemption before exiting
do_debug(), after disabling interrupts. I've noticed that the task can be
preempted either at the end of an interrupt, or on the call to
force_sig_info() on the spin_unlock_irqrestore() processing. It might be
better to attempt to code a fix in entry.S around the code that calls
do_debug().

Subject: [PATCH 0544/1267] [PATCH] x86_64: GART DMA merging fix
Don't touch the non DMA members in the sg list in dma_map_sg in the IOMMU
Some drivers (in particular ST) ran into problems because they reused the sg
lists after passing them to pci_map_sg(). The merging procedure in the K8
GART IOMMU corrupted the state. This patch changes it to only touch the dma*
entries during merging, but not the other fields. Approach suggested by Dave
Miller.

This patch reduces the default L2CAP MTU for all RFCOMM connections
from 1024 to 1013 to improve the interoperability with some broken
RFCOMM implementations. To make this more flexible the L2CAP MTU
becomes also a module parameter and so it can changed at runtime.

Subject: [PATCH 0550/1267] [Bluetooth] Fix firmware loading problem of BT3C
driver
Before the PCMCIA subsystem was fully integrated into the device and
driver model, the BT3C driver had to workaround this when loading the
firmware. This workaround is broken and makes the driver oops when
loading the firmware. This patch removes this workaround and uses now
the provided device structure from the PCMCIA subsystem.

there's a problem with IPsec that has been bugging some of our users
for the last couple of kernel revs. Every now and then, IPsec will
freeze the machine completely. This is with openswan user land,
and with kernels up to and including 2.6.16-rc2.
I managed to debug this a little, and what happens is that we end
up looping in xfrm_lookup, and never get out. With a bit of debug
printks added, I can this happening:
ip_route_output_flow calls xfrm_lookup
xfrm_find_bundle returns NULL (apparently we're in the
middle of negotiating a new SA or something)
We therefore call xfrm_tmpl_resolve. This returns EAGAIN
We go to sleep, waiting for a policy update.
Then we loop back to the top
Apparently, the dst_orig that was passed into xfrm_lookup
has been dropped from the routing table (obsolete=2)
This leads to the endless loop, because we now create
a new bundle, check the new bundle and find it's stale
(stale_bundle -> xfrm_bundle_ok -> dst_check() return 0)
People have been testing with the patch below, which seems to fix the
problem partially. They still see connection hangs however (things
only clear up when they start a new ping or new ssh). So the patch
is obvsiouly not sufficient, and something else seems to go wrong.
I'm grateful for any hints you may have...
I suggest that we simply bail out always. If the dst decides to die
on us later on, the packet will be dropped anyway. So there is no
great urgency to retry here. Once we have the proper resolution
queueing, we can then do the retry again.

parisc defines ARCH_WANT_STAT64, so we want to use fstatat64. It does not
appear that it needs to be ENTRY_COMP, because struct stat64 is the same
on both 32-bit and 64-bit (unlike on other platforms which did define a
compat_sys_fstatat64.)

Also make the kernel warnings reporting BIOS handoff problems be more useful,
reporting the register whose value displays the trouble.

Use the real-time status registers of the Winbond W83782D, W83783S and
W83627HF chips, instead of the interrupt status registers. Interrupts
cannot be trusted at least for voltage inputs, as they are two-times
triggers (as opposed to comparator mode, which we want.) The w83627hf
driver was fixed in a similar way some times ago.

Probe and remove methods are now defined at bus level. No more need to
redefine them at driver level in i2c-isa.
This lets us get rid of these annoying messages:
Driver 'it87-isa' needs updating - please use bus_type methods
Thanks to Nicolas Mailhot for reporting the problem and testing the fix.

Subject: [PATCH 0582/1267] [PATCH] x86: fix oprofile kernel callgraph
regression
Fix x86 oprofile regression introduced by:
commit c34d1b4d165c67b966bca4aba026443d7ff161eb
[PATCH] mm: kill check_user_page_readable
That commit reorganized tests for the userspace stack walking moving all
those tests into dump_backtrace(), however, dump_backtrace() was used for
both userspace and kernel stalk walking. The result is typically no
recorded callgraph information for kernel samples.
Revive the original function as dump_kernel_backtrace() and rename the
other to dump_user_backtrace() to avoid future confusion.

Subject: [PATCH 0583/1267] [PATCH] add scsi_execute_in_process_context() API
We have several points in the SCSI stack (primarily for our device
functions) where we need to guarantee process context, but (given the
place where the last reference was released) we cannot guarantee this.
This API gets around the issue by executing the function directly if
the caller has process context, but scheduling a workqueue to execute
in process context if the caller doesn't have it. Unfortunately, it
requires memory allocation in interrupt context, but it's better than
what we have previously. The true solution will require a bit of
re-engineering, so isn't appropriate for 2.6.16.

Subject: [PATCH 0584/1267] [SCSI] fix wrong context bugs in SCSI
There's a bug in releasing scsi_device where the release function
actually frees the block queue. However, the block queue release
calls flush_work(), which requires process context (the scsi_device
structure may release from irq context). Update the release function
to invoke via the execute_in_process_context() API.
Also clean up the scsi_target structure releasing via this API.

From 63077519899721120b61d663a68adced068a459d Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Wed, 8 Feb 2006 01:48:03 +0900
Subject: [PATCH 0590/1267] [MIPS] Rewrite get_wchan and its helper functions
using kallsyms_lookup.
Implement get_wchan() and frame_info_init() using kallsyms_lookup().
This fixes problem with static sched/lock functions and mfinfo[]
maintenance issue. If CONFIG_KALLSYMS was disabled, get_wchan() just
returns thread_saved_pc() value.
Also unwind stackframe based on "addiu sp,-imm" analysis instead of
frame pointer. This fixes problem with functions compiled without
-fomit-frame-pointer.

Subject: [PATCH 0591/1267] [MIPS] Add protected_blast_icache_range,
blast_icache_range, etc.
Add blast_xxx_range(), protected_blast_xxx_range() etc. for common
use. They are built by __BUILD_BLAST_CACHE_RANGE().
Use protected_cache_op() macro for various protected_ routines.
Output code should be logically same.

Subject: [PATCH 0592/1267] [MIPS] More uaccess.h fixes with gcc >= 4.0.1.
From Richard Sandiford <richard@codesourcery.com>:
This patch caused a miscompilation of the restore_gp_regs() block
in restore_sigcontext(). This was in a 32-bit kernel compiled with
GCC CVS head.
restore_gp_regs() copies 64-bit user fields into 32-bit variables,
and in this combination, the new __get_user_asm_ll32() clobbers too
many registers. It says:
/*
* Get a long long 64 using 32 bit registers.
*/
{ \
__asm__ __volatile__( \
"1: lw %1, (%3) \n" \
"2: lw %D1, 4(%3) \n" \
" move %0, $0 \n" \
"3: .section .fixup,\"ax\" \n" \
"4: li %0, %4 \n" \
" move %1, $0 \n" \
" move %D1, $0 \n" \
" j 3b \n" \
" .previous \n" \
" .section __ex_table,\"a\" \n" \
" " __UA_ADDR " 1b, 4b \n" \
" " __UA_ADDR " 2b, 4b \n" \
" .previous \n" \
: "=r" (__gu_err), "=&r" (val) \
: "0" (0), "r" (addr), "i" (-EFAULT)); \
}
and this requires val (%1) to be a 64-bit value. In the case I saw,
gcc was using $3 for the 32-bit val, and wasn't expecting $4 to be
clobbered.

Subject: [PATCH 0600/1267] [IA64] Count disabled cpus as potential
hot-pluggable CPUs
Have a facility to account for potentially hot-pluggable CPUs. ACPI doesnt
give a determinstic method to find hot-pluggable CPUs. Hence we use 2 methods
to assist.
- BIOS can mark potentially hot-pluggable CPUs as disabled in the MADT tables.
- User can specify the number of hot-pluggable CPUs via parameter
additional_cpus=X
The option is enabled only if ACPI_CONFIG_HOTPLUG_CPU=y which enables the
physical hotplug option. Without which user can still use logical onlining
and offlining of CPUs by enabling CONFIG_HOTPLUG_CPU=y
Adds more bits to cpu_possible_map for potentially hot-pluggable cpus.

Subject: [PATCH 0605/1267] [PATCH] compound page: use page[1].lru
If a compound page has its own put_page_testzero destructor (the only current
example is free_huge_page), that is noted in page[1].mapping of the compound
page. But that's rather a poor place to keep it: functions which call
set_page_dirty_lock after get_user_pages (e.g. Infiniband's
__ib_umem_release) ought to be checking first, otherwise set_page_dirty is
liable to crash on what's not the address of a struct address_space.
And now I'm about to make that worse: it turns out that every compound page
needs a destructor, so we can no longer rely on hugetlb pages going their own
special way, to avoid further problems of page->mapping reuse. For example,
not many people know that: on 50% of i386 -Os builds, the first tail page of a
compound page purports to be PageAnon (when its destructor has an odd
address), which surprises page_add_file_rmap.
Keep the compound page destructor in page[1].lru.next instead. And to free up
the common pairing of mapping and index, also move compound page order from
index to lru.prev. Slab reuses page->lru too: but if we ever need slab to use
compound pages, it can easily stack its use above this.
(akpm: decoded version of the above: the tail pages of a compound page now
have ->mapping==NULL, so there's no need for the set_page_dirty[_lock]()
caller to check that they're not compund pages before doing the dirty).

Subject: [PATCH 0606/1267] [PATCH] compound page: default destructor
Somehow I imagined that calling a NULL destructor would free a compound page
rather than oopsing. No, we must supply a default destructor, __free_pages_ok
using the order noted by prep_compound_page. hugetlb can still replace this
as before with its own free_huge_page pointer.
The case that needs this is not common: rarely does put_compound_page's
put_page_testzero bring the count down to 0. But if get_user_pages is applied
to some part of a compound page, without immediate release (e.g. AIO or
Infiniband), then it's possible for its put_page to come after the containing
vma has been unmapped and the driver done its free_pages.
That's just the kind of case compound pages are supposed to be guarding
against (but Nick points out, nor did PageReserved handle this right).

Fix hole where tty structure can be released when reference count is non
zero. Existing code can sleep without tty_sem protection between deciding
to release the tty structure (setting local variables tty_closing and
otty_closing) and setting TTY_CLOSING to prevent further opens. An open
can occur during this interval causing release_dev() to free the tty
structure while it is still referenced.
This should fix bugzilla.kernel.org [Bug 6041] New: Unable to handle kernel
paging request
In Bug 6041, tty_open() oopes on accessing the tty structure it has
successfully claimed. Bug was on SMP machine with the same tty being
opened and closed by multiple processes, and DEBUG_PAGEALLOC enabled.

Subject: [PATCH 0609/1267] [PATCH] HPET: handle multiple ACPI EXTENDED_IRQ
resources
When the _CRS for a single HPET contains multiple EXTENDED_IRQ resources,
we overwrote hdp->hd_nirqs every time we found one.
So the driver worked when all the IRQs were described in a single
EXTENDED_IRQ resource, but failed when multiple resources were used.
(Strictly speaking, I think the latter is actually more correct, but both
styles have been used.)
Someday we should remove all the ACPI stuff from hpet.c and use PNP driver
registration instead. But currently PNP_MAX_IRQ is 2, and HPETs often have
more IRQs. Hint, hint, Adam :-)

From 7c8903f6373f9abecf060bad53ca36bc4ac037f2 Mon Sep 17 00:00:00 2001
From: Mark Fasheh <mark.fasheh@oracle.com>
Date: Tue, 14 Feb 2006 13:53:03 -0800
Subject: [PATCH 0610/1267] [PATCH] jbd: revert checkpoint list changes
This patch reverts commit f93ea411b73594f7d144855fd34278bcf34a9afc:
[PATCH] jbd: split checkpoint lists
This broke journal_flush() for OCFS2, which is its method of being sure
that metadata is sent to disk for another node.
And two related commits 8d3c7fce2d20ecc3264c8d8c91ae3beacdeaed1b and
43c3e6f5abdf6acac9b90c86bf03f995bf7d3d92 with the subjects:
[PATCH] jbd: log_do_checkpoint fix
[PATCH] jbd: remove_transaction fix
These seem to be incremental bugfixes on the original patch and as such are
no longer needed.

arguments (i.e. same offset+length - actually quite common, since most
processes try to lock the entire file) then the first GRANTED call that wakes
one up will also wake the other.
Currently when the NLM_GRANTED callback comes in, lockd walks the list of
blocked locks in search of a match to the lock that the NLM server has
granted. Although it checks the lock pid, start and end, it fails to check
the filehandle and the server address.
By checking the filehandle and server IP address, we ensure that this only
happens if the locks truly are referencing the same file.

Subject: [PATCH 0615/1267] [PATCH] madvise MADV_DONTFORK/MADV_DOFORK
Currently, copy-on-write may change the physical address of a page even if the
user requested that the page is pinned in memory (either by mlock or by
get_user_pages). This happens if the process forks meanwhile, and the parent
writes to that page. As a result, the page is orphaned: in case of
get_user_pages, the application will never see any data hardware DMA's into
this page after the COW. In case of mlock'd memory, the parent is not getting
the realtime/security benefits of mlock.
In particular, this affects the Infiniband modules which do DMA from and into
user pages all the time.
This patch adds madvise options to control whether memory range is inherited
across fork. Useful e.g. for when hardware is doing DMA from/into these
pages. Could also be useful to an application wanting to speed up its forks
by cutting large areas out of consideration.

Subject: [PATCH 0616/1267] [PATCH] sched: revert "filter affine wakeups"
Revert commit d7102e95b7b9c00277562c29aad421d2d521c5f6:
[PATCH] sched: filter affine wakeups
Apparently caused more than 10% performance regression for aim7 benchmark.
The setup in use is 16-cpu HP rx8620, 64Gb of memory and 12 MSA1000s with 144
disks. Each disk is 72Gb with a single ext3 filesystem (courtesy of HP, who
supplied benchmark results).
The problem is, for aim7, the wake-up pattern is random, but it still needs
load balancing action in the wake-up path to achieve best performance. With
the above commit, lack of load balancing hurts that workload.
However, for workloads like database transaction processing, the requirement
is exactly opposite. In the wake up path, best performance is achieved with
absolutely zero load balancing. We simply wake up the process on the CPU that
it was previously run. Worst performance is obtained when we do load
balancing at wake up.
There isn't an easy way to auto detect the workload characteristics. Ingo's
earlier patch that detects idle CPU and decide whether to load balance or not
doesn't perform with aim7 either since all CPUs are busy (it causes even
bigger perf. regression).
Revert commit d7102e95b7b9c00277562c29aad421d2d521c5f6, which causes more
than 10% performance regression with aim7.

Subject: [PATCH 0619/1267] [PATCH] hrtimer: round up relative start time on
low-res arches
CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that
they simply return xtime in do_gettimeoffset(). In this corner-case we
want to round up by resolution when starting a relative timer, to avoid
short timeouts. This will go away with the GTOD framework.

Subject: [PATCH 0620/1267] [PATCH] FRV: Miscellaneous fixes
Make various alterations and fixes to the FRV arch:
(1) Resyncs the FRV system call collection with the i386 arch.
(2) Discards __iounmap() as it's not used.
(3) Fixes the use of the SWAP/SWAPI instruction to get the arguments the right
way around in atomic.h, and also to get the asm constraints correct.
(4) Moves copy_to/from_user_page() to asm/cacheflush.h to be consistent with
other archs.

Subject: [PATCH 0621/1267] [PATCH] FRV: Use virtual interrupt disablement
Make the FRV arch use virtual interrupt disablement because accesses to the
processor status register (PSR) are relatively slow and because we will
soon have the need to deal with multiple interrupt controls at the same
time (separate h/w and inter-core interrupts).
The way this is done is to dedicate one of the four integer condition code
registers (ICC2) to maintaining a virtual interrupt disablement state
whilst inside the kernel. This uses the ICC2.Z flag (Zero) to indicate
whether the interrupts are virtually disabled and the ICC2.C flag (Carry)
to indicate whether the interrupts are physically disabled.
ICC2.Z is set to indicate interrupts are virtually disabled. ICC2.C is set
to indicate interrupts are physically enabled. Under normal running
conditions Z==0 and C==1.
Disabling interrupts with local_irq_disable() doesn't then actually
physically disable interrupts - it merely sets ICC2.Z to 1. Should an
interrupt then happen, the exception prologue will note ICC2.Z is set and
branch out of line using one instruction (an unlikely BEQ). Here it will
physically disable interrupts and clear ICC2.C.
When it comes time to enable interrupts (local_irq_enable()), this simply
clears the ICC2.Z flag and invokes a trap #2 if both Z and C flags are
clear (the HI integer condition). This can be done with the TIHI
conditional trap instruction.
The trap then physically reenables interrupts and sets ICC2.C again. Upon
returning the interrupt will be taken as interrupts will then be enabled.
Note that whilst processing the trap, the whole exceptions system is
disabled, and so an interrupt can't happen till it returns.
If no pending interrupt had happened, ICC2.C would still be set, the HI
condition would not be fulfilled, and no trap will happen.
Saving interrupts (local_irq_save) is simply a matter of pulling the ICC2.Z
flag out of the CCR register, shifting it down and masking it off. This
gives a result of 0 if interrupts were enabled and 1 if they weren't.
Restoring interrupts (local_irq_restore) is then a matter of taking the
saved value mentioned previously and XOR'ing it against 1. If it was one,
the result will be zero, and if it was zero the result will be non-zero.
This result is then used to affect the ICC2.Z flag directly (it is a
condition code flag after all). An XOR instruction does not affect the
Carry flag, and so that bit of state is unchanged. The two flags can then
be sampled to see if they're both zero using the trap (TIHI) as for the
unconditional reenablement (local_irq_enable).
This patch also:
(1) Modifies the debugging stub (break.S) to handle single-stepping crossing
into the trap #2 handler and into virtually disabled interrupts.
(2) Removes superseded fixup pointers from the second instructions in the trap
tables (there's no a separate fixup table for this).
(3) Declares the trap #3 vector for use in .org directives in the trap table.
(4) Moves irq_enter() and irq_exit() in do_IRQ() to avoid problems with
virtual interrupt handling, and removes the duplicate code that has now
been folded into irq_exit() (softirq and preemption handling).
(5) Tells the compiler in the arch Makefile that ICC2 is now reserved.
(6) Documents the in-kernel ABI, including the virtual interrupts.
(7) Renames the old irq management functions to different names.

+ =================================
+ INTERNAL KERNEL ABI FOR FR-V ARCH
+ =================================
+
+The internal FRV kernel ABI is not quite the same as the userspace ABI. A number of the registers
+are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs
+no-MMU.
+
+This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and
+most of them do not have any scratch registers, thus requiring at least one general purpose
+register to be clobbered in such an event. Also, within the kernel core, it is possible to simply
+jump or call directly between functions using a relative offset. This cannot be extended to modules
+for the displacement is likely to be too far. Thus in modules the address of a function to call
+must be calculated in a register and then used, requiring two extra instructions.
+
+This document has the following sections:
+
+ (*) System call register ABI
+ (*) CPU operating modes
+ (*) Internal kernel-mode register ABI
+ (*) Internal debug-mode register ABI
+ (*) Virtual interrupt handling
+
+
+========================
+SYSTEM CALL REGISTER ABI
+========================
+
+When a system call is made, the following registers are effective:
+
+ REGISTERS CALL RETURN
+ =============== ======================= =======================
+ GR7 System call number Preserved
+ GR8 Syscall arg #1 Return value
+ GR9-GR13 Syscall arg #2-6 Preserved
+
+
+===================
+CPU OPERATING MODES
+===================
+
+The FR-V CPU has three basic operating modes. In order of increasing capability:
+
+ (1) User mode.
+
+ Basic userspace running mode.
+
+ (2) Kernel mode.
+
+ Normal kernel mode. There are many additional control registers available that may be
+ accessed in this mode, in addition to all the stuff available to user mode. This has two
+ submodes:
+
+ (a) Exceptions enabled (PSR.T == 1).
+
+ Exceptions will invoke the appropriate normal kernel mode handler. On entry to the
+ handler, the PSR.T bit will be cleared.
+
+ (b) Exceptions disabled (PSR.T == 0).
+
+ No exceptions or interrupts may happen. Any mandatory exceptions will cause the CPU to
+ halt unless the CPU is told to jump into debug mode instead.
+
+ (3) Debug mode.
+
+ No exceptions may happen in this mode. Memory protection and management exceptions will be
+ flagged for later consideration, but the exception handler won't be invoked. Debugging traps
+ such as hardware breakpoints and watchpoints will be ignored. This mode is entered only by
+ debugging events obtained from the other two modes.
+
+ All kernel mode registers may be accessed, plus a few extra debugging specific registers.
+
+
+=================================
+INTERNAL KERNEL-MODE REGISTER ABI
+=================================
+
+There are a number of permanent register assignments that are set up by entry.S in the exception
+prologue. Note that there is a complete set of exception prologues for each of user->kernel
+transition and kernel->kernel transition. There are also user->debug and kernel->debug mode
+transition prologues.
+
+
+ REGISTER FLAVOUR USE
+ =============== ======= ====================================================
+ GR1 Supervisor stack pointer
+ GR15 Current thread info pointer
+ GR16 GP-Rel base register for small data
+ GR28 Current exception frame pointer (__frame)
+ GR29 Current task pointer (current)
+ GR30 Destroyed by kernel mode entry
+ GR31 NOMMU Destroyed by debug mode entry
+ GR31 MMU Destroyed by TLB miss kernel mode entry
+ CCR.ICC2 Virtual interrupt disablement tracking
+ CCCR.CC3 Cleared by exception prologue (atomic op emulation)
+ SCR0 MMU See mmu-layout.txt.
+ SCR1 MMU See mmu-layout.txt.
+ SCR2 MMU Save for EAR0 (destroyed by icache insns in debug mode)
+ SCR3 MMU Save for GR31 during debug exceptions
+ DAMR/IAMR NOMMU Fixed memory protection layout.
+ DAMR/IAMR MMU See mmu-layout.txt.
+
+
+Certain registers are also used or modified across function calls:
+
+ REGISTER CALL RETURN
+ =============== =============================== ===============================
+ GR0 Fixed Zero -
+ GR2 Function call frame pointer
+ GR3 Special Preserved
+ GR3-GR7 - Clobbered
+ GR8 Function call arg #1 Return value (or clobbered)
+ GR9 Function call arg #2 Return value MSW (or clobbered)
+ GR10-GR13 Function call arg #3-#6 Clobbered
+ GR14 - Clobbered
+ GR15-GR16 Special Preserved
+ GR17-GR27 - Preserved
+ GR28-GR31 Special Only accessed explicitly
+ LR Return address after CALL Clobbered
+ CCR/CCCR - Mostly Clobbered
+
+
+================================
+INTERNAL DEBUG-MODE REGISTER ABI
+================================
+
+This is the same as the kernel-mode register ABI for functions calls. The difference is that in
+debug-mode there's a different stack and a different exception frame. Almost all the global
+registers from kernel-mode (including the stack pointer) may be changed.
+
+ REGISTER FLAVOUR USE
+ =============== ======= ====================================================
+ GR1 Debug stack pointer
+ GR16 GP-Rel base register for small data
+ GR31 Current debug exception frame pointer (__debug_frame)
+ SCR3 MMU Saved value of GR31
+
+
+Note that debug mode is able to interfere with the kernel's emulated atomic ops, so it must be
+exceedingly careful not to do any that would interact with the main kernel in this regard. Hence
+the debug mode code (gdbstub) is almost completely self-contained. The only external code used is
+the sprintf family of functions.
+
+Futhermore, break.S is so complicated because single-step mode does not switch off on entry to an
+exception. That means unless manually disabled, single-stepping will blithely go on stepping into
+things like interrupts. See gdbstub.txt for more information.
+
+
+==========================
+VIRTUAL INTERRUPT HANDLING
+==========================
+
+Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once
+to read and once to write), we don't actually disable interrupts at all if we don't have to. What
+we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we
+then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume
+execution at the point the interrupt happened. Setting condition flags as a side effect of an
+arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the
+kernel - it does not affect userspace.
+
+The flags we use are:
+
+ (*) CCR.ICC2.Z [Zero flag]
+
+ Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be
+ modified by logical instructions without affecting the Carry flag.
+
+ (*) CCR.ICC2.C [Carry flag]
+
+ Clear to indicate hardware interrupts are really disabled, set otherwise.
+
+
+What happens is this:
+
+ (1) Normal kernel-mode operation.
+
+ ICC2.Z is 0, ICC2.C is 1.
+
+ (2) An interrupt occurs. The exception prologue examines ICC2.Z and determines that nothing needs
+ doing. This is done simply with an unlikely BEQ instruction.
+
+ (3) The interrupts are disabled (local_irq_disable)
+
+ ICC2.Z is set to 1.
+
+ (4) If interrupts were then re-enabled (local_irq_enable):
+
+ ICC2.Z would be set to 0.
+
+ A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would be used to trap if
+ interrupts were now virtually enabled, but physically disabled - which they're not, so the
+ trap isn't taken. The kernel would then be back to state (1).
+
+ (5) An interrupt occurs. The exception prologue examines ICC2.Z and determines that the interrupt
+ shouldn't actually have happened. It jumps aside, and there disabled interrupts by setting
+ PSR.PIL to 14 and then it clears ICC2.C.
+
+ (6) If interrupts were then saved and disabled again (local_irq_save):
+
+ ICC2.Z would be shifted into the save variable and masked off (giving a 1).
+
+ ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be unaffected (ie: 0).
+
+ (7) If interrupts were then restored from state (6) (local_irq_restore):
+
+ ICC2.Z would be set to indicate the result of XOR'ing the saved value (ie: 1) with 1, which
+ gives a result of 0 - thus leaving ICC2.Z set.
+
+ ICC2.C would remain unaffected (ie: 0).
+
+ A TIHI #2 instruction would be used to again assay the current state, but this would do
+ nothing as Z==1.
+
+ (8) If interrupts were then enabled (local_irq_enable):
+
+ ICC2.Z would be cleared. ICC2.C would be left unaffected. Both flags would now be 0.
+
+ A TIHI #2 instruction again issued to assay the current state would then trap as both Z==0
+ [interrupts virtually enabled] and C==0 [interrupts really disabled] would then be true.
+
+ (9) The trap #2 handler would simply enable hardware interrupts (set PSR.PIL to 0), set ICC2.C to
+ 1 and return.
+
+(10) Immediately upon returning, the pending interrupt would be taken.
+
+(11) The interrupt handler would take the path of actually processing the interrupt (ICC2.Z is
+ clear, BEQ fails as per step (2)).
+
+(12) The interrupt handler would then set ICC2.C to 1 since hardware interrupts are definitely
+ enabled - or else the kernel wouldn't be here.
+
+(13) On return from the interrupt handler, things would be back to state (1).
+
+This trap (#2) is only available in kernel mode. In user mode it will result in SIGILL.

Subject: [PATCH 0624/1267] [PATCH] neofb: avoid resetting display config on
unblank
Fix issues with the NeoMagic framebuffer driver.
It nicely complements my previous fix already in linus' tree. The only
thing missing now is that the external CRT will not be activated at neofb
init when external-only is selected, either by register read or
module/kernel parameter.
Testing was done on a Dell Latitude CPi-A/NM2200 chip.
Previous behaviour:
- before booting linux, set the preferred display config X via FN+F8
- boot linux, neofb stores the register values in a private
variable
- change the display config to Y via keystroke
- leave the machine in peace until display is blanked
- touching any key will result in display config X being restored
- booting up, the BIOS will acknowledge config Y, though...
Current behaviour:
At the time of unblanking, config Y is honoured because we now read back
register contents instead of just overwriting them with outdated values.

From: David Brownell <dbrownell@users.sourceforge.net>
Date: Wed, 15 Feb 2006 00:49:35 -0500
Subject: [PATCH 0630/1267] Input: ads7846 - assorted updates
This updates the ads7846 touchscreen driver:
- to allow faster clocking (this driver doesn't push sample rates);
- bugfixes the conversion of spi_transfer to lists;
- some dma-unsafe command buffers are fixed.

Subject: [PATCH 0632/1267] [NETFILTER]: Fix xfrm lookup after SNAT
To find out if a packet needs to be handled by IPsec after SNAT, packets
are currently rerouted in POST_ROUTING and a new xfrm lookup is done. This
breaks SNAT of non-unicast packets to non-local addresses because the
packet is routed as incoming packet and no neighbour entry is bound to the
dst_entry. In general, it seems to be a bad idea to replace the dst_entry
after the packet was already sent to the output routine because its state
might not match what's expected.
This patch changes the xfrm lookup in POST_ROUTING to re-use the original
dst_entry without routing the packet again. This means no policy routing
can be used for transport mode transforms (which keep the original route)
when packets are SNATed to match the policy, but it looks like the best
we can do for now.

Subject: [PATCH 0637/1267] [PATCH] fix kill_proc_info() vs CLONE_THREAD race
There is a window after copy_process() unlocks ->sighand.siglock
and before it adds the new thread to the thread list.
In that window __group_complete_signal(SIGKILL) will not see the
new thread yet, so this thread will start running while the whole
thread group was supposed to exit.
I beleive we have another good reason to place attach_pid(PID/TGID)
under ->sighand.siglock. We can do the same for
release_task()->__unhash_process()
de_thread()->switch_exec_pids()
After that we don't need tasklist_lock to iterate over the thread
list, and we can simplify things, see for example do_sigaction()
or sys_times().

Subject: [PATCH 0638/1267] [PATCH] fix kill_proc_info() vs fork() theoretical
race
copy_process:
attach_pid(p, PIDTYPE_PID, p->pid);
attach_pid(p, PIDTYPE_TGID, p->tgid);
What if kill_proc_info(p->pid) happens in between?
copy_process() holds current->sighand.siglock, so we are safe
in CLONE_THREAD case, because current->sighand == p->sighand.
Otherwise, p->sighand is unlocked, the new process is already
visible to the find_task_by_pid(), but have a copy of parent's
'struct pid' in ->pids[PIDTYPE_TGID].
This means that __group_complete_signal() may hang while doing
do ... while (next_thread() != p)
We can solve this problem if we reverse these 2 attach_pid()s:
attach_pid() does wmb()
group_send_sig_info() calls spin_lock(), which
provides a read barrier. // Yes ?
I don't think we can hit this race in practice, but still.

From: Jes Sorensen <jes@sgi.com>
Date: Mon, 13 Feb 2006 05:29:57 -0500
Subject: [PATCH 0641/1267] [IA64-SGI] sn2 minor fixes and cleanups
General SN2 code cleanup:
- Do not initialize global variables to zero
- Use kzalloc instead of kmalloc+memset
- Check kmalloc return values
- Do not obfuscate spin lock calls
- Remove some unused code
- Various formatting cleanups

The __sn_cnodeid_to_nasid array was incorrectly sized at MAX_NUMNODES.
On a large system, this array could overflow. The following patch
corrects this by defining it to MAX_COMPACT_NODES.

Subject: [PATCH 0647/1267] [IA64] ia64: simplify and fix udelay()
The original ia64 udelay() was simple, but flawed for platforms without
synchronized ITCs: a preemption and migration to another CPU during the
while-loop likely resulted in too-early termination or very, very
lengthy looping.
The first fix (now in 2.6.15) broke the delay loop into smaller,
non-preemptible chunks, reenabling preemption between the chunks. This
fix is flawed in that the total udelay is computed to be the sum of just
the non-premptible while-loop pieces, i.e., not counting the time spent
in the interim preemptible periods. If an interrupt or a migration
occurs during one of these interim periods, then that time is invisible
and only serves to lengthen the effective udelay().
This new fix backs out the current flawed fix and returns to a simple
udelay(), fully preemptible and interruptible. It implements two simple
alternative udelay() routines: one a default generic version that uses
ia64_get_itc(), and the other an sn-specific version that uses that
platform's RTC.

Subject: [PATCH 0648/1267] [XFRM]: Fix SNAT-related crash in
xfrm4_output_finish
When a packet matching an IPsec policy is SNATed so it doesn't match any
policy anymore it looses its xfrm bundle, which makes xfrm4_output_finish
crash because of a NULL pointer dereference.
This patch directs these packets to the original output path instead. Since
the packets have already passed the POST_ROUTING hook, but need to start at
the beginning of the original output path which includes another
POST_ROUTING invocation, a flag is added to the IPCB to indicate that the
packet was rerouted and doesn't need to pass the POST_ROUTING hook again.

If skb->ip_summed is CHECKSUM_HW here, skb->csum includes checksum

Subject: [PATCH 0656/1267] [PATCH] neofb: avoid resetting display config on
unblank (v2)
There were two mistakes in the register-read-on-(un)blank approach.
- First, without proper register (un)locking the value read back will always
be zero, and this is what I missed entirely until just now. Due to this,
the logic could not be verified at all and I tried some bogus checks which
are completely stupid.
- Second, the LCD status bit will always be set to zero when the backlight
has been turned off. Reading the value back during unblank will disable the
LCD unconditionally, regardless of the state it is supposed to be in, since
we set it to zero beforehand.
So this is what we do now:
- create a new variable in struct neofb_par, and use that to determine
whether to read back registers (initialized to true)
- before actually blanking the screen, read back the register to sense any
possible change made through Fn key combo
- use proper neoUnlock() / neoLock() to actually read something
- every call to neofb_blank() determines if we read back next time: blanking
disables readback, unblanking (FB_BLANK_UNBLANK) enables it
This should give us a nice and clean state machine. Has been thoroughly
tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached
CRT in all possible combinations of LCD/CRT on/off. I changed the config via
Fn key, let the console blank, unblanked by keypress - works flawlessly.

Fix a latent bug in cpuset_exit() handling. If a task tried to allocate
memory after calling cpuset_exit(), it oops'd in
cpuset_update_task_memory_state() on a NULL cpuset pointer.
So set the exiting tasks cpuset to the root cpuset instead of to NULL.
A distro kernel hit this with an added kernel package that had just such a
hook (allocating memory) in the exit code path.

Subject: [PATCH 0662/1267] [PATCH] x86_64: early initialization of cpu_to_node
The early initialization of cpu_to_node code as it is now only updates the
cpu_to_node array, and does not update cpu_pda()->nodemember. This will
cause numa_node_id() to return 0 on systems where CPU 0 is not on Node 0.
This leads to a kernel panic in slab.c.
I've tested the patch below on a 16 processor x86_64 ES7000-600 server, and
no longer see the panic I saw with the original 2.6.16-rc3.

Subject: [PATCH 0665/1267] [ARM] Fix SMP initialisation oops
A change to the SMP initialisation caused the following oops:
CPU1: Booted secondary processor
CPU1: D VIPT write-back cache
CPU1: I cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets
CPU1: D cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets
<7>Calibrating delay loop... 83.14 BogoMIPS (lpj=415744)

...
PC is at enqueue_task+0x1c/0x64
LR is at activate_task+0xcc/0xe4
SMP initialisation now requires cpu_possible_map to be initialised in
setup_arch(). Move this from smp_prepare_cpus() to smp_init_cpus()
and call it from our setup_arch() if CONFIG_SMP is enabled.

Subject: [PATCH 0666/1267] [PATCH] Fix over-zealous tag clearing in
radix_tree_delete
If a tag is set for a node being deleted from a radix_tree, then that
tag gets cleared from the parent of the node, even if it is set for some
siblings of the node begin deleted.
This patch changes the logic to include a test for any_tag_set similar
to the logic a little futher down. Care is taken to ensure that
'nr_cleared_tags' remains equals to the number of entries in the 'tags'
array which are set to '0' (which means that this tag is not set in the
tree below pathp->node, and should be cleared at pathp->node and
possibly above.
[ Nick says: "Linus FYI, I was able to modify the radix tree test
harness to catch the bug and can no longer trigger it after the fix.
Resulting code passes all other harness tests as well of course." ]

If a data transfer is small (less than a FIFO size) we would
hang waiting for the data to be read due to the PIO interrupt
not occuring. We allowed for this in our PIO interrupt handler,
but not when setting up a data transfer.
Apply the "fix" when setting up a data transfer as well.

Subject: [PATCH 0681/1267] [PATCH] wireless/atmel: fix Open System
authentication process bugs
This patch fixes a number of bugs in the authentication process:
1) When falling back to Shared Key authentication mode from Open System,
a missing 'return' would cause the auth request to be sent, but would
drop the card into Management Error state. When falling back, the
driver should also indicate that it is switching to Shared Key mode by
setting exclude_unencrypted.
2) Initial authentication modes were apparently wrong in some cases,
causing the driver to attempt Shared Key authentication mode when in
fact the access point didn't support that mode or even had WEP disabled.
The driver should set the correct initial authentication mode based on
wep_is_on and exclude_unencrypted.
3) Authentication response packets from the access point in Open System
mode were getting ignored because the driver was expecting the sequence
number of a Shared Key mode response. The patch separates the OS and SK
mode handling to provide the correct behavior.

in enable_timer_nmi_watchdog()).

AMD SimNow!'s JIT doesn't like them at all in the guest. For distribution
installation it's easiest if it's a boot time option.
Also I moved the variable to a more appropiate place and make
it independent from sysctl
And marked __read_mostly which it is.

workaround when the machine has C2 or C3
Many laptops have problems with ticking the local APIC timer in C2/C3.
The code added earlier to use it by default on ATI didn't really work
for them. Don't enable it when the system supports C2/C3.
This doesn't fix the problem fully, but at least it's not worse than before.

Subject: [PATCH 0691/1267] [PATCH] Handle all and empty zones when setting up
custom zonelists for mbind
The memory allocator doesn't like empty zones (which have an
uninitialized freelist), so a x86-64 system with a node fully
in GFP_DMA32 only would crash on mbind.
Fix that up by putting all possible zones as fallback into the zonelist
and skipping the empty ones.
In fact the code always enough allocated space for all zones,
but only used it for the highest. This change just uses all the
memory that was allocated before.
This should work fine for now, but whoever implements node hot removal
needs to fix this somewhere else too (or make sure zone datastructures
by itself never go away, only their memory)

Subject: [PATCH 0692/1267] [PATCH] Provide an interface for getting the
current tick length
This provides an interface for arch code to find out how many
nanoseconds are going to be added on to xtime by the next call to
do_timer. The value returned is a fixed-point number in 52.12 format
in nanoseconds. The reason for this format is that it gives the
full precision that the timekeeping code is using internally.
The motivation for this is to fix a problem that has arisen on 32-bit
powerpc in that the value returned by do_gettimeofday drifts apart
from xtime if NTP is being used. PowerPC is now using a lockless
do_gettimeofday based on reading the timebase register and performing
some simple arithmetic. (This method of getting the time is also
exported to userspace via the VDSO.) However, the factor and offset
it uses were calculated based on the nominal tick length and weren't
being adjusted when NTP varied the tick length.
Note that 64-bit powerpc has had the lockless do_gettimeofday for a
long time now. It also had an extremely hairy routine that got called
from the 32-bit compat routine for adjtimex, which adjusted the
factor and offset according to what it thought the timekeeping code
was going to do. Not only was this only called if a 32-bit task did
adjtimex (i.e. not if a 64-bit task did adjtimex), it was also
duplicating computations from kernel/timer.c and it wasn't clear that
it was (still) correct.
The simple solution is to ask the timekeeping code how long the
current jiffy will be on each timer interrupt, after calling
do_timer. If this jiffy will be a different length from the last one,
we then need to compute new values for the factor and offset used in
the lockless do_gettimeofday. In this way we can keep xtime and
do_gettimeofday in sync, even when NTP is varying the tick length.
Note that when adjtimex varies the tick length, it almost always
introduces the variation from the next tick on. The only case I could
see where adjtimex would vary the length of the current tick is when
an old-style adjtime adjustment is being cancelled. (It's not clear
to me why the adjustment has to be cancelled immediately rather than
from the next tick on.) Thus I don't see any real need for a hook in
adjtimex; the rare case of an old-style adjustment being cancelled can
be fixed up at the next tick.

Subject: [PATCH 0698/1267] [PATCH] skge: speed setting
This is a clone of John Linville's fixed for speed setting on sky2 driver.
The skge driver has the same code (and bug). It would not allow manually forcing
100 and 10 mbit.

Subject: [PATCH 0699/1267] [PATCH] sky2: speed setting fix
Users report problems w/ auto-negotiation disabled and the link set
to 100/Half or 10/Half. Problems range from poor performance to no
link at all.
The current sky2 code does not set things properly on link up if
autonegotiation is disabled. Plus it does not contemplate a 10Mbit
setting at all. This patch corrects that.

[patch 1/2] s390: lcs performance enhancements
From: Klaus Wacker <kdwacker@de.ibm.com>
- When flood pinging (with large packet size) an LCS device,
about 90 % of all packets are dropped by driver.
- increased number of lcs IO buffers to 32.
- use netif_stop_queue/netif_wake_queue in lcs_start_xmit routine
- don't lock the whole xmit routine but just the piece of code where
tx_buffer is touched.

From: Frank Pavlic <fpavlic@de.ibm.com>
- fixed kernel panic when using EDDP support in Layer 2 mode
- NULL pointer exception in qeth_set_offline fixed.
- setting EDDP in Layer 2 mode did not set NETIF_F_(SG/TSO)
flags when device became online.
- use sscanf for parsing and converting IPv4 addresses
from string to __u8 values.
- qeth_string_to_ipaddr6 fixed. in case of double colon
the converted IPv6 address out from the string was not correct
in previous implementation.

Subject: [PATCH 0708/1267] [PATCH] fix deadlock in ext2
Fix a deadlock possible in the ext2 file system implementation. This
deadlock occurs when a file is removed from an ext2 file system which was
mounted with the "sync" mount option.
The problem is that ext2_xattr_delete_inode() was invoking the routine,
sync_dirty_buffer(), using a buffer head which was previously locked via
lock_buffer(). The first thing that sync_dirty_buffer() does is to lock
the buffer head that it was passed. It does this via lock_buffer(). Oops.
The solution is to unlock the buffer head in ext2_xattr_delete_inode()
before invoking sync_dirty_buffer(). This makes the code in
ext2_xattr_delete_inode() obey the same locking rules as all other callers
of sync_dirty_buffer() in the ext2 file system implementation.

Heiko Carstens <heiko.carstens@de.ibm.com> wrote:
The boot sequence on s390 sometimes takes ages and we spend a very long
time (up to one or two minutes) in calibrate_migration_costs. The time
spent there differs from boot to boot. Also the calculated costs differ
a lot. I've seen differences by up to a factor of 15 (yes, factor not
percent). Also I doubt that making these measurements make much sense on
a completely virtualized architecture where you cannot tell how much cpu
time you will get anyway.
So introduce the CONFIG_DEFAULT_MIGRATION_COST method for an architecture
to set the scheduler migration costs. This turns off automatic detection
of migration costs. Makes sense on virtual platforms, where migration
costs are hard to measure accurately.

Subject: [PATCH 0713/1267] [PATCH] s390: fix preempt_count of idle thread with
cpu hotplug
Set preempt_count of idle_thread to zero before switching off cpu. Otherwise
the preempt_count will be wrong if the cpu is switched on again since the
thread will be reused.

Subject: [PATCH 0714/1267] [PATCH] s390: additional_cpus parameter
Introduce additional_cpus command line option. By default no additional cpu
can be attached to the system anymore. Only the cpus present at IPL time can
be switched on/off. If it is desired that additional cpus can be attached to
the system the maximum number of additional cpus needs to be specified with
this option.
This change is necessary in order to limit the waste of per_cpu data
structures.

Introduce possible_cpus command line option. Hard sets the number of bits set
in cpu_possible_map. Unlike the additional_cpus parameter this one guarantees
that num_possible_cpus() will stay constant even if the system gets rebooted
and a different number of cpus are present at startup.

Subject: [PATCH 0716/1267] [PATCH] s390: smp initialization speed
The last changes that introduced the additional_cpus command line parameter
also introduced a regression regarding smp initialization speed. In
smp_setup_cpu_possible_map() cpu_present_map is set to the same value as
cpu_possible_map. Especially that means that bits in the present map will be
set for cpus that are not present. This will cause a slow down in the initial
cpu_up() loop in smp_init() since trying to take cpus online that aren't
present takes a while.
Fix this by setting only bits for present cpus in cpu_present_map and set
cpu_present_map to cpu_possible_map in smp_cpus_done().

Subject: [PATCH 0720/1267] [PATCH] fuse: fix bug in aborted fuse_release_end()
There's a rather theoretical case of the BUG triggering in
fuse_reset_request():
- iget() fails because of OOM after a successful CREATE_OPEN request
- during IO on the resulting RELEASE request the connection is aborted
Fix and add warning to fuse_reset_request().

Subject: [PATCH 0721/1267] [PATCH] allow windfarm_pm112 module to load
The windfarm_pm112 module relies on smu_sat_get_sdb_partition which is in
windfarm_smu_sat.c but is not exported to modules, so despite Kconfig
having the option to build the pm112 as modules, this can never be loaded.
This patch fixes that by exporting smu_sat_get_sdb_partition with
EXPORT_SYMBOL_GPL

Subject: [PATCH 0726/1267] [PATCH] ACPI: fix vendor resource length
computation
acpi_rs_get_list_length() needs to account for all the vendor-defined data
bytes. Failing to include these causes buffers to be sized too small,
which causes slab corruption when we later convert AML to resources and run
off the end of the buffer.
This causes slab corruption on machines that use ACPI vendor-defined
resources. All HP ia64 machines do, and I'm told that some NEC machines
may as well.

Subject: [PATCH 0732/1267] [PATCH] don't mangle INQUIRY if cmddt or evpd bits
are set
sbp2.c mangles INQUIRY response in a way that only applies to standard
inquiry data (i.e. when both cmddt and evpd bits are 0). Leave other cases
alone; e.g. when asking for VPD the length of reply is in byte 3, not 4
and byte 4 is the first byte of device serial number.

1) it should use nr_processes(), not nr_threads; otherwise we are getting
very confused find(1) and friends, among other things.
2) better do that at stat() time than at every damn lookup in procfs root.
Patch had been sitting in FC4 kernels for many months now...

Subject: [PATCH 0738/1267] powerpc: Keep xtime and gettimeofday in sync
This fixes a regression which was introduced by moving ppc32 to use
the same sort of lockless gettimeofday as ppc64 has been using for
some time. This involves getting the timebase and performing some
simple arithmetic to convert it to seconds and microseconds. However,
the factor and offset used there weren't being updated when NTP
varied the tick length using adjtimex. 64-bit didn't notice the
problem because it had a hook in the 32-bit adjtimex compat routine
that attempted to work out what the generic timekeeping code would
do and alter the factor and offset to match. However, that code
was very complex and it wasn't clear that it still matched what the
generic code would do.
Now we use the generic current_tick_length() routine that was recently
added to check that the current tick will be as long as we expect; if
not we recompute the factor and offset. This keeps gettimeofday and
xtime in sync. In addition we check that gettimeofday hasn't got ahead
of xtime on each timer interrupt; if it has, we resync.

Subject: [PATCH 0741/1267] [PATCH] powerpc: Don't start secondary CPUs in a UP
&& KEXEC kernel
Because smp_release_cpus() is built for SMP || KEXEC, it's not safe to
unconditionally call it from setup_system(). On a UP && KEXEC kernel we'll
start up the secondary CPUs which will then go beserk and we die.
Simple fix is to conditionally call smp_release_cpus() in setup_system(). With
that in place we don't need the dummy definition of smp_release_cpus() because
all call sites are #ifdef'ed either SMP or KEXEC.

Subject: [PATCH 0743/1267] [PATCH] powerpc: Fix bug in spinup of renumbered
secondary threads
If the logical and physical cpu ids of a secondary thread don't match, we will
fail to spin the thread up on pSeries machines due to a bug in pseries/smp.c
We call the RTAS "start-cpu" method with the physical cpu id, the address of
pSeries_secondary_smp_init and the value to pass that function in r3. Currently
we pass "lcpu", the logical cpu id, but pSeries_secondary_smp_init expects
the physical cpu id in r3.
We should be passing pcpu instead.

Subject: [PATCH 0745/1267] [NETFILTER]: Fix NAT PMTUD problems
ICMP errors are only SNATed when their source matches the source of the
connection they are related to, otherwise the source address is not
changed. This creates problems with ICMP frag. required messages
originating from a router behind the NAT, if private IPs are used the
packet has a good change of getting dropped on the path to its destination.
Always NAT ICMP errors similar to the original connection.
Based on report by Al Viro.

Subject: [PATCH 0746/1267] [IRDA]: irda-usb bug fixes
This patch fixes 2 bugs in the USB-IrDA code.
The first one is a buffer overrun in the RX path. We are now using
IRDA_SKB_MAX_MTU when initializing the Rx URB.
The second one is a potential stack recursion when unplugging the USB
dongle. It seems that first we get the Rx URB with a generic error
code, and after a while the Rx URB comes again with a "disconnect"
error code. Since we are resubmitting the Rx URB immediately after
receiving the first error one, we might enter an endless loop.
When getting an error Rx URB, the patch defers the Rx URB resubmitting
so that it gives us a chance to catch the disconnect one, in case the
dongle has juts been unplugged.
Tested against 2.6.16-rc2.

Subject: [PATCH 0747/1267] [NETFILTER]: Fix outgoing redirects to loopback
When redirecting an outgoing packet to loopback, it keeps the original
conntrack reference and information from the outgoing path, which
falsely triggers the check for DNAT on input and the dst_entry is
released to trigger rerouting. ip_route_input refuses to route the
packet because it has a local source address and it is dropped.
Look at the packet itself to dermine if it was NATed. Also fix a
missing inversion that causes unneccesary xfrm lookups.

Subject: [PATCH 0749/1267] [PATCH] libata: fix WARN_ON() condition in
*_fill_sg()
For ATAPI commands, padding can reduce qc->n_elem by one and thus to
zero making assert(qc->n_elem > 0)'s in ata_fill_sg() and qs_fill_sg()
fail for legal commands. This patch fixes the assert()'s to take
qc->pad_len into account.
Although the condition check seems a bit excessive, as this part of
code isn't still stable yet, I think it's worth to keep those.

Subject: [PATCH 0750/1267] [PATCH] libata: fix qc->n_elem == 0 case handling
in ata_qc_next_sg
This patch makes ata_for_each_sg() start with pad_sgent when
qc->n_elem is zero. Previously, ata_for_each_sg() unconditionally
started with qc->__sg, handling the first sg to fill_sg() routines
even when the entry was invalid. And while at it, unwind ?: in
ata_qc_next_sg() into if statement.

Subject: [PATCH 0753/1267] [PATCH] OOM kill: children accounting
In the badness() calculation, there's currently this piece of code:
/*
* Processes which fork a lot of child processes are likely
* a good choice. We add the vmsize of the children if they
* have an own mm. This prevents forking servers to flood the
* machine with an endless amount of children
*/
list_for_each(tsk, &p->children) {
struct task_struct *chld;
chld = list_entry(tsk, struct task_struct, sibling);
if (chld->mm = p->mm && chld->mm)
points += chld->mm->total_vm;
}
The intention is clear: If some server (apache) keeps spawning new children
and we run OOM, we want to kill the father rather than picking a child.
This -- to some degree -- also helps a bit with getting fork bombs under
control, though I'd consider this a desirable side-effect rather than a
feature.
There's one problem with this: No matter how many or few children there are,
if just one of them misbehaves, and all others (including the father) do
everything right, we still always kill the whole family. This hits in real
life; whether it's javascript in konqueror resulting in kdeinit (and thus the
whole KDE session) being hit or just a classical server that spawns children.
Sidenote: The killer does kill all direct children as well, not only the
selected father, see oom_kill_process().
The idea in attached patch is that we do want to account the memory
consumption of the (direct) children to the father -- however not fully.
This maintains the property that fathers with too many children will still
very likely be picked, whereas a single misbehaving child has the chance to
be picked by the OOM killer.
In the patch I account only half (rounded up) of the children's vm_size to
the parent. This means that if one child eats more mem than the rest of
the family, it will be picked, otherwise it's still the father and thus the
whole family that gets selected.
This is heuristics -- we could debate whether accounting for a fourth would
be better than for half of it. Or -- if people would consider it worth the
trouble -- make it a sysctl. For now I sticked to accounting for half,
which should IMHO be a significant improvement.
The patch does one more thing: As users tend to be irritated by the choice
of killed processes (mainly because the children are killed first, despite
some of them having a very low OOM score), I added some more output: The
selected (father) process will be reported first and it's oom_score printed
to syslog.
Description:
Only account for half of children's vm size in oom score calculation
This should still give the parent enough point in case of fork bombs. If
any child however has more than 50% of the vm size of all children
together, it'll get a higher score and be elected.
This patch also makes the kernel display the oom_score.

Subject: [PATCH 0754/1267] [PATCH] Terminate process that fails on a
constrained allocation
Some allocations are restricted to a limited set of nodes (due to memory
policies or cpuset constraints). If the page allocator is not able to find
enough memory then that does not mean that overall system memory is low.
In particular going postal and more or less randomly shooting at processes
is not likely going to help the situation but may just lead to suicide (the
whole system coming down).
It is better to signal to the process that no memory exists given the
constraints that the process (or the configuration of the process) has
placed on the allocation behavior. The process may be killed but then the
sysadmin or developer can investigate the situation. The solution is
similar to what we do when running out of hugepages.
This patch adds a check before we kill processes. At that point
performance considerations do not matter much so we just scan the zonelist
and reconstruct a list of nodes. If the list of nodes does not contain all
online nodes then this is a constrained allocation and we should kill the
current process.

Subject: [PATCH 0756/1267] [PATCH] cfi_cmdset_0001: fix range for cache
invalidation
I found an issue in cfi_cmdset0001.c. It is related to cache region
invalidation in the buffered write procedure.
The code performs cache invalidation from "cmd_addr" to "cmd_adr + len" in
do_write_buffer() while we modify region from "adr" to "adr+len".
This issue affects writes + reads of data by small chunks.

Subject: [PATCH 0760/1267] [PATCH] suspend-to-ram: allow video options to be
set at runtime
Currently, acpi video options can only be set on kernel command line. That's
little inflexible; I'd like userland s2ram application that just works, and
modifying kernel command line according to whitelist is not fun. It is better
to just allow s2ram application to set video options just before suspend
(according to the whitelist).
This implements sysctl to allow setting suspend video options without reboot.
(akpm: Documentation updates for this new sysctl are pending..)

Subject: [PATCH 0769/1267] [PATCH] powermac: Fix loss of ethernet PHY on sleep
Some recent PowerBook models tend to lose the ethernet PHY on
suspend/resume. It -seems- that they use a combo ethernet-firewire PHY
chip and the firewire PHY seems to die the same way when that happens. Not
trying to toggle the firewire cable power appears to fix it. So this patch
disables changes to the firewire cable power control GPIO on those models.

Subject: [PATCH 0775/1267] [PATCH] radeonfb: resume support for Samsung P35
laptops
Make resume from suspend-to-ram possible for Samsung P35 laptops.
The radeon mobility 9700 chip on Samsung P35 laptops locks up everything on
resume from suspend-to-ram if it is not reinitialized.
VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
Class 0300: 1002:4e50
Subsystem: 144d:c00c
Unfortunately, the DMI strings are mostly identical for all Samsung
laptops. So we match the PCI ID and subsystem ID of the graphics card
which is unique for each Samsung laptop model.

Subject: [PATCH 0776/1267] [PATCH] s390: V=V qdio fixes
Using FCP devices with V=V support, the input queue stalled when CCQ 97 had
been returned in qdio_do_eqbs. When this happen we have to reissue the eqbs
instruction.
Another bug was when V=V was enabled we checked if hardware has SIGA-sync
support. If not we returned with 0 from tiqdio_is_inbound_q_done. Thus qdio
lost initiative on FCP devices and input queue stalled. Running devices in
V=V there is no SIGA-sync support but nevertheless we have to process
tiqdio_is_inbound_q_done either.

Subject: [PATCH 0777/1267] [PATCH] s390: dasd reference counting
When using the dasd diag discipline, the base discipline module (eckd or fba)
can be unloaded, even though the dasd driver requires both discipline modules
(base and diag) to work correctly.
Implement reference counting for both base and diag discipline modules in
order to fix this.

- * The internal buffer is meant to store obaque blobs of data, so it doesn't
- * know of higher level concepts like triggers.
- * It consists of a number of pages that are used as a ringbuffer. Each data
- * blob is stored in a simple record that consists of an integer, which
- * contains the size of the following data, and the data bytes themselfes.
- *
- * To allow for multiple independent readers we create one internal buffer
- * each time the device is opened and destroy the buffer when the file is
- * closed again.
- *
- * One record can be written to a buffer by using the functions
- * - dasd_eer_start_record (one time per record to write the size to the buffer
- * and reserve the space for the data)
- * - dasd_eer_write_buffer (one or more times per record to write the data)
- * The data can be written in several steps but you will have to compute
- * the total size up front for the invocation of dasd_eer_start_record.
- * If the ringbuffer is full, dasd_eer_start_record will remove the required

-/* The extended error reporting functionality */
-/*****************************************************************************/
-
-/*
- * When a DASD device driver wants to report an error, it calls the
- * function dasd_eer_write_trigger (via a notifier mechanism) and gives the
- * respective trigger ID as parameter.
- * Currently there are four kinds of triggers:
- *
- * DASD_EER_FATALERROR: all kinds of unrecoverable I/O problems
- * DASD_EER_PPRCSUSPEND: PPRC was suspended
- * DASD_EER_NOPATH: There is no path to the device left.
- * DASD_EER_STATECHANGE: The state of the device has changed.
- *
- * For the first three triggers all required information can be supplied by
- * the caller. For these triggers a record is written by the function
- * dasd_eer_write_standard_trigger.
- *
- * When dasd_eer_write_trigger is called to write a DASD_EER_STATECHANGE
- * trigger, we have to gather the necessary sense data first. We cannot queue
- * the necessary SNSS (sense subsystem status) request immediatly, since we
- * are likely to run in a deadlock situation. Instead, we schedule a
- * work_struct that calls the function dasd_eer_sense_subsystem_status to
- * create and start an SNSS request asynchronously.
- *
- * To avoid memory allocations at runtime, the necessary memory is allocated
- * when the extended error reporting is enabled for a device (by
- * dasd_eer_probe). There is one private eer data structure for each eer
- * enabled DASD device. It contains memory for the work_struct, one SNSS cqr
- * and a flags field that is used to coordinate the use of the cqr. The call
- * to write a state change trigger can come in at any time, so we have one flag
- * CQR_IN_USE that protects the cqr itself. When this flag indicates that the
- * cqr is currently in use, dasd_eer_sense_subsystem_status cannot start a
- * second request but sets the SNSS_REQUESTED flag instead.
- *
- * When the request is finished, the callback function dasd_eer_SNSS_cb
- * is called. This function will invoke the function
- * dasd_eer_write_SNSS_trigger to finally write the trigger. It will also
- * check the SNSS_REQUESTED flag and if it is set it will call
- * dasd_eer_sense_subsystem_status again.
- *
- * To avoid race conditions during the handling of the lock, the flags must
- * be protected by the snsslock.

This patch fixes a bug of include/asm-m32r/system.h:__cmpxchg_u32().
static __inline__ unsigned long
__cmpxchg_u32(volatile unsigned int *p, unsigned int old, unsigned int new);
In __cmpxchg_u32(), the "old" value must not be changed to the previous "*p"
value. But the former code modifies the previous "*p" value.
A deadlock at _atomic_dec_and_lock sometimes happened due to this bug.

Subject: [PATCH 0780/1267] [PATCH] m32r: update sys_tas() routine
This patch updates and fixes sys_tas() routine for m32r.
In the previous implementation, a lockup rarely caused at sys_tas()
routine in SMP environment.
> > The problem is that touching *addr will generate an oops if that page isn't
> > paged in. If we convert it to use get_user() then that's an improvement,
> > but we must not run get_user() under spinlock or local_irq_disable().
I rewrote sys_tas() routine by using "lock -> unlock" instructions, and
utilizing the m32r's interrupt handling characteristics; the m32r processor
can accept interrupts only at the 32-bit instruction boundary. So, the
"unlock" instruction can be executed continuously after the "lock"
instruction execution without any interruptions.
In addition, to solve such a page_fault problem, I use a fixup code like
get_user().
And, as for the kernel lockup problem, we found that a calling
do_page_fault() routine with disabling interrupts might cause a lockup at
flush_tlb_others(), because we checked a completion of IPI handler's
operations in a spin-locked critical section.
Therefore, by using "lock -> unlock" code, we can implement the sys_tas()
rouitine without disabling interrupts explicitly, then no lockups would
happen at flush_tlb_others(), I hope.
Compile check and some working test in SMP environment have done.

In daemonize() a new thread gets cleaned up and 'merged' with init_task.
The current fs_struct is handled there, but not the current namespace.
This adds the namespace part.
[ Eric Biederman pointed out the namespace wrappers, and also notes that
we can't ever count on using our parents namespace because we already
have called exit_fs(), which is the only way to the namespace from a
process. ]

Subject: [PATCH 0784/1267] [MIPS] Fixes for uaccess.h with gcc >= 4.0.1
It seems current get_user() incorrectly sign-extend an unsigned int
value on 64bit kernel. I think this is because '(__typeof__(val))'
cast in final assignment. I suppose the cast should be
'(__typeof__(*(addr))'.

Subject: [PATCH 0785/1267] [MIPS] Add support for TIF_RESTORE_SIGMASK for
signal32
Following the recent implementation of TIF_RESTORE_SIGMASK in
arch/mips/kernel/signal.c, 64-bit kernels with 32-bit user-land
compatibility oops when starting init. signal32.c needs to be
converted to use TIF_RESTORE_SIGMASK too.

Subject: [PATCH 0794/1267] [MIPS] Add topology_init.
A recent patch introduced cpu topology in sysfs. When you run a kernel
with SMP and sysfs enabled, you now get an Oops on boot. The following
patch fixes that by adding topology_init to arch/mips/kernel/smp.c. The
code is copied from arch/s390/kernel/smp.c.

Subject: [PATCH 0798/1267] [PATCH] tmpfs: fix mount mpol nodelist parsing
I've been dissatisfied with the mpol_nodelist mount option which was
added to tmpfs earlier in -rc. Replace it by mpol=policy:nodelist.
And it was broken: a nodelist is a comma-separated list of numbers and
ranges; the mount options are a comma-separated list of token=values.
Whoops, blindly strsep'ing on commas doesn't work so well: since we've
no numeric tokens, and unlikely to add them, use that to distinguish.
Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject
all its options as invalid if not NUMA. /proc shows MPOL_PREFERRED
as "prefer", so use that name for the policy instead of "preferred".
Enforce that mpol=default has no nodelist; that mpol=prefer has one
node only; that mpol=bind has a nodelist; but let mpol=interleave use
node_online_map if no nodelist given. Describe this in tmpfs.txt.

Subject: [PATCH 0803/1267] Revert mount/umount uevent removal
This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit
from Kay Sievers that removed the mount/umount uevents from the kernel.
Some older versions of HAL still depend on these events to detect when a
new device has been mounted. These events are not correctly emitted,
and are broken by design, and so, should not be relied upon by any
future program. Instead, the /proc/mounts file should be polled to
properly detect this kind of event.
A feature-removal-schedule.txt entry has been added, noting when this
interface will be removed from the kernel.

Subject: [PATCH 0804/1267] [ARM] 3340/1: Fix the PCI setup for direct master
access to SDRAM
Patch from Catalin Marinas
The initial code did not configure the inbound memory windows for direct
master access to the SDRAM. This patch creates a 1:1 mapping between the
Versatile/PB PCI memory windows and its SDRAM. Note that an updated FPGA
image is needed for Versatile/PB since the original windows were 1MB and
not able to cover the whole SDRAM (now extended to 256MB). The patch also
fixes the PCI IRQ mapping for slot #2.

* FIXME: for now, we just copy the alarm time because we're lazy (and

This patch adds one day to the alarm iff the alarm wrapped beyond midnight and therefore appears to be in the past.

Subject: [PATCH 0810/1267] [ARM] 3325/2: GPIO function to control multi-drive
(open collector) capability
Patch from Andrew Victor
This patch adds the at91_set_multi_drive() function to enable/disable
the multi-drive (open collector) pin capability on the AT91RM9200
processor.
This is necessary to fix the UDC (USB Gadget) driver for the AT91RM9200
board as it will not allow the board reset line to be pulled low if the
pullup is not driven as an open collector output as the boards are wired
to the USB connector on both the DK/EK.
This version of the patch updates it to 2.6.16-rc4.
Orignal patch by Jeff Warren.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Patch from Mårten Wikström
This patch fixes a bug in ixp4xx_set_irq_type() which leads to
GPIO being incorrectly set to both edge triggered for raising
as well as falling edge interrupt types. See the previous
discussion on patch 3312/1.

Subject: [PATCH 0815/1267] [PATCH] sky2: limit coalescing values to ring size
Don't allow coalescing values to be bigger than the transmit ring.
Since if you set them that big, the interrupt never happens and driver
livelocks.

Subject: [PATCH 0817/1267] [PATCH] sky2: force early transmit status
Need to force a transmit coalesce timer restart after processing
transmit packets. Otherwise, can get transmit status after last
update and chip doesn't send the next one.
Can go with the chip defaults for coalescing timers, except for
Tx timer which needs to be bigger.

Subject: [PATCH 0818/1267] [PATCH] sky2: use device iomem to access PCI config
To avoid problems with PCI config access without ACPI (or busted ACPI tables),
use the device's window into PCI config space.
I know this probably will upset the purists, but I would rather have users
than ACPI testers. It also generates less code.

Subject: [PATCH 0820/1267] sbp2: fix another deadlock after disconnection
If there were commands enqueued but not completed before an SBP-2 unit
was unplugged (or an attempt to reconnect failed), knodemgrd or any
process which tried to remove the device would sleep uninterruptibly
in blk_execute_rq(). Therefore make sure that all commands are
completed when sbp2 retreats.

Subject: [PATCH 0821/1267] sbp2: variable status FIFO address (fix login
timeout)
Let the ieee1394 core select a suitable 1394 address range for sbp2's
status FIFO instead of using a fixed range. Since the core only selects
addresses which are guaranteed to be out of the "physical range" as per
OHCI 1.1, this patch also fixes an old bug:
OHCI controllers which implement a writeable PhysicalUpperBound register
included sbp2's status FIFO in the physical range. That way sbp2 was
never notified of a succesful login and always failed after timeout.
Affected OHCI host adapters include ALi and Fujitsu controllers.
As another side effect of this patch, the status FIFO is no longer
located in a range for which OHCI chips perform "posted writes". Each
status write now requires a response subaction. But since large data
transfers involve only few status writes, there is no measurable
decrease of I/O throughput. What's more, the status FIFO is now safe
from potential host bus errors. Nevertheless, posted writes could be
re-enabled by extensions to the ARM features of the 1394 stack.

Subject: [PATCH 0822/1267] sbp2: update 36byte inquiry workaround (fix
compatibility regression)
Since about Linux 2.6.14, sbp2's inquiry workaround did not work anymore
due to changes in the SCSI layer. Update it to become effective again.
Testing one of the two known affected bridges has shown that skip_ms_page_8
is required as well.
Also, make force_inquiry_hack tunable via /sys/module/sbp2/parameters.

Subject: [PATCH 0831/1267] [NETFILTER]: Fix bridge netfilter related in
xfrm_lookup
The bridge-netfilter code attaches a fake dst_entry with dst->ops == NULL
to purely bridged packets. When these packets are SNATed and a policy
lookup is done, xfrm_lookup crashes because it tries to dereference
dst->ops.
Change xfrm_lookup not to dereference dst->ops before checking for the
DST_NOXFRM flag and set this flag in the fake dst_entry.

Subject: [PATCH 0832/1267] [IPV4]: Fix garbage collection of multipath route
entries
When garbage collecting route cache entries of multipath routes
in rt_garbage_collect(), entries were deleted from the hash bucket
'i' while holding a spin lock on bucket 'k' resulting in a system
hang. Delete entries, if any, from bucket 'k' instead.

Subject: [PATCH 0833/1267] [XFRM]: Eliminate refcounting confusion by creating
__xfrm_state_put().
We often just do an atomic_dec(&x->refcnt) on an xfrm_state object
because we know there is more than 1 reference remaining and thus
we can elide the heavier xfrm_state_put() call.
Do this behind an inline function called __xfrm_state_put() so that is
more obvious and also to allow us to more cleanly add refcount
debugging later.

Subject: [PATCH 0834/1267] [NET] ethernet: Fix first packet goes out with MAC
00:00:00:00:00:00
When you turn off ARP on a netdevice then the first packet always goes
out with a dstMAC of all zeroes. This is because the first packet is
used to resolve ARP entries. Even though the ARP entry may be resolved
(I tried by setting a static ARP entry for a host i was pinging from),
it gets overwritten by virtue of having the netdevice disabling ARP.
Subsequent packets go out fine with correct dstMAC address (which may
be why people have ignored reporting this issue).
To cut the story short:
the culprit code is in net/ethernet/eth.c::eth_header()
----
/*
* Anyway, the loopback-device should never use this
function...
*/
if (dev->flags & (IFF_LOOPBACK|IFF_NOARP))
{
memset(eth->h_dest, 0, dev->addr_len);
return ETH_HLEN;
}
if(daddr)
{
memcpy(eth->h_dest,daddr,dev->addr_len);
return ETH_HLEN;
}
----
Note how the h_dest is being reset when device has IFF_NOARP.
As a note:
All devices including loopback pass a daddr. loopback in fact passes
a 0 all the time ;->
This means i can delete the check totaly or i can remove the IFF_NOARP
Alexey says:
--------------------
I think, it was me who did this crap. It was so long ago I do not remember
why it was made.
I remember some troubles with dummy device. It tried to resolve
addresses, apparently, without success and generated errors instead of
blackholing. I think the problem was eventually solved at neighbour
level.
After some thinking I suspect the deletion of this chunk could change
behaviour of some parts which do not use neighbour cache f.e. packet
socket.
I think safer approach would be to move this chunk after if (daddr).
And the possibility to remove this completely could be analyzed later.
--------------------
Patch updated with Alexey's safer suggestions.

Subject: [PATCH 0837/1267] [PATCH] powerpc: Only calculate htab_size in one
place for kexec
For kexec we need to know the size of the MMU hash table.
Currently we calculate the size once in the htab code, and then twice more in
the kexec code, once using htab_hash_mask and once using ppc64_pft_size.
On some machines the ppc64_pft_size calculation is broken because
ppc64_pft_size is not set.
So we need to fix the second calculation, but better still we should just
calculate the size once and use it everywhere else.
Tested on Power5 LPAR, Power4 non-LPAR and Power3.

timeout value for kdump
The panic CPU is waiting forever due to some large timeout value if some
CPU is not responding to an IPI.
This patch fixes the problem - the maximum waiting period will be
10 seconds and then the kdump boot will go ahead.

Subject: [PATCH 0840/1267] [PATCH] powerpc: fix altivec_unavailable_exception
Oopses
altivec_unavailable_exception is called without setting r3... it looks like
the r3 that actually gets passed in as struct pt_regs *regs is the
undisturbed value of r3 at the time the altivec instruction was encountered.
The user actually gets to choose the pt_regs printed in the Oops!
This fixes the oops by passing the correct pt_regs pointer to
altivec_unavailable_exception.

Subject: [PATCH 0844/1267] [PATCH] powerpc: Fix runlatch performance issues
The runlatch SPR can take a lot of time to write. My original runlatch
code would set it on every exception entry even though most of the time
this was not required. It would also continually set it in the idle
loop, which is an issue on an SMT capable processor.
Now we cache the runlatch value in a threadinfo bit, and only check for
it in decrementer and hardware interrupt exceptions as well as the idle
loop. Boot on POWER3, POWER5 and iseries, and compile tested on pmac32.

Subject: [PATCH 0845/1267] [PATCH] powerpc64: remove broken/bitrotted HMT
support
HMT support is currently broken and needs to be reworked to play nicely
with the SMT scheduler. Remove the bit rotten bits for the time being.
I also updated an incorrect comment, we enter __secondary_hold with the
physical cpu id in r3.

Subject: [PATCH 0847/1267] [PATCH] powerpc: Fix some MPIC + HT APIC buglets
Do disable, not enable, the HT APIC IRQ in the function that is
supposed to.
Enable the MPIC IRQ before enabling the downstream APIC IRQ, avoids
potentially losing an interrupt.

Maple firmware does not need PCI resource allocation, and in fact, it
can cause problems in some strange cases.

Subject: [PATCH 0849/1267] [PATCH] Fix race condition in hvc console.
tty_schedule_flip() would schedule a thread that would call flush_to_ldisc().
If tty_buffer_request_room() gets called prior to that thread running --
which is likely in this loop in hvc_poll(), it would set the active flag
in the tty buffer and consequently flush_to_ldisc() would ignore it.
The result is that input on the hvc console is not processed.
This fix calls tty_flip_buffer_push (and flags the tty as
"low_latency"). The push to the ldisc thus happens synchronously.

Subject: [PATCH 0850/1267] [PATCH] drivers/net/tlan.c: #ifdef CONFIG_PCI the
PCI specific code
drivers/net/tlan.c compiles with CONFIG_PCI=n only with a warning and
due to the dead code elimination of gcc.
Additionally, this fixes the only compile error I found with
CONFIG_PCI=n and the gcc -Werror-implicit-function-declaration
flag on i386.

Subject: [PATCH 0856/1267] [ARM] 3348/1: Disable GPIO interrupts
Patch from Andrew Victor
disable_irq() lazily disables the interrupt, so the IRQ is only disabled
once the interrupt occurs again. The GPIO interrupt handler therefore
must first check disable_depth to see if the IRQ needs to be disabled.
Orignal patch by Bill Gatliff.

Subject: [PATCH 0857/1267] [PATCH] m32r: enable asm code optimization
Add -O2 option to AFLAGS to enable asm code optimization for m32r.
On m32r gas, "-m32r2 -O" option enables assembler's parallel code
generation optimization for M32R2 ISA as a default. So, "-no-parallel"
option is required explicitly for a cpu core with single instuction
issuing, for example, VDEC2.

Subject: [PATCH 0858/1267] [PATCH] m32r: fix and update for gcc-4.0
Fix and update for gcc-4.0.
- arch/m32r/kernel/signal.c:
Change type of the 8th parameter of sys_rt_sigsuspend() from
'struct pt_regs' to 'struct pt_regs *'.
This functions make use of the 'regs' parameter to return status value,
but gcc-4.0 optimizes and removes it as a dead code.
Functions, sys_sigaltstack() and sys_rt_sigreturn(), have also modified.
- arch/m32r/lib/usercopy.c, include/asm-m32r/uaccess.h:
Add early-clobber constraints('&') to output values of asm statements;
these constraints seems to be required for gcc-4.0 register assignment.

errno
To avoid conflicts, in kernel files errno is expanded to kernel_errno, to
distinguish it from glibc errno. In this case, the code wants to use the libc
errno but the kernel one is used; in the other usage, we return errno in place
of -errno in case of an error.

Subject: [PATCH 0867/1267] [PATCH] vgacon: no vertical resizing on EGA
EGA boards suck: they mostly have write-only registers. This is
particularly problematic for the overflow register: for being able to write
to it, we would have to handle vertical sync & such too, which (I'd say)
would potentially break a lot of configurations. Instead, just disabling
vertical resize for EGA boards is just nice enough (horizontal resize still
works).

Fix a problem seen on i686 machine with NX support where the instruction
could not be single stepped because of NX bit set on the memory pages
allocated by kprobes module. This patch provides allocation of instruction
solt so that the processor can execute the instruction from that location
similar to x86_64 architecture. Thanks to Bibo and Masami for testing this
patch.

Right at the moment (thanks to a patch from Andrew), cpu_possible_map on

Subject: [PATCH 0872/1267] [PATCH] page migration: Fix MPOL_INTERLEAVE
behavior for migration via mbind()
migrate_pages_to() allocates a list of new pages on the intended target
node or with the intended policy and then uses the list of new pages as
targets for the migration of a list of pages out of place.
When the pages are allocated it is not clear which of the out of place
pages will be moved to the new pages. So we cannot specify an address as
needed by alloc_page_vma(). This causes problem for MPOL_INTERLEAVE which
will currently allocate the pages on the first node of the set. If mbind
is used with vma that has the policy of MPOL_INTERLEAVE then the
interleaving of pages may be destroyed.
This patch fixes that by generating a fake address for each alloc_page_vma
which will result is a distribution of pages as prescribed by
MPOL_INTERLEAVE.
Lee also noted that the sequence of nodes for the new pages seems to be
inverted. So we also invert the way the lists of pages for migration are
build.

Subject: [PATCH 0873/1267] [PATCH] x86: fix broken SMP boot sequence
Recent GDT changes broke the SMP boot sequence if the booting CPU is
numbered anything other than zero. There's also a subtle source of error
in that the boot time CPU now uses cpu_gdt_table (which is actually the GDT
for booting CPUs in head.S). This patch fixes both problems by making GDT
descriptors themselves allocated from a per_cpu area and switching to them
in cpu_init(), which now means that cpu_gdt_table is exclusively used for
booting CPUs again.

Subject: [PATCH 0878/1267] [PATCH] flags parameter for linkat
I'm currently at the POSIX meeting and one thing covered was the
incompatibility of Linux's link() with the POSIX definition. The name.
Linux does not follow symlinks, POSIX requires it does.
Even if somebody thinks this is a good default behavior we cannot change this
because it would break the ABI. But the fact remains that some application
might want this behavior.
We have one chance to help implementing this without breaking the behavior.
For this we could use the new linkat interface which would need a new
flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new
behavior could be invoked.
I do not want to introduce such a patch now. But we could add the
parameter now, just don't use it. The patch below would do this. Can we
get this late patch applied before the release more or less fixes the
syscall API?

Subject: [PATCH 0879/1267] [PATCH] vmscan: fix zone_reclaim
- PF_SWAPWRITE needs to be set for RECLAIM_SWAP to be able to write
out pages to swap. Currently RECLAIM_SWAP may not do that.
- remove setting nr_reclaimed pages after slab reclaim since the slab shrinking
code does not use that and the nr_reclaimed pages is just right for the
intended follow up action.

Subject: [PATCH 0884/1267] [PATCH] Fix topology.c location
When compiling a non-default subarch, topology.c is missing from the kernel
build. This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition,
on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to
reference uninitialized data that should have been set up by the initcall
in topology.c which calls register_cpu. This causes a kernel panic on boot
on newer Intel processors. Moving topology.c to arch/i386/kernel fixes
both of these problems.
Thanks to Dan Hecht for finding and fixing this problem.

Subject: [PATCH 0888/1267] [PATCH] sata_sil: implement R_ERR on DMA activate
FIS errata fix
Silicon Image has disclosed a new sil3114/3152 errata and workaround
which causes the controller to return R_ERR on DMA activate FIS if the
FIS is received while the next PRD is being fetched. This patch
implements the workaround.
This errata results in lock up and doesn't trigger if m15w workaround
is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1
which makes 3512/3114 lock up with some drives on all kernel versions
since 2.6.14-rc1 upto now (2.6.16-rc4). This patch should fix the
regression.

Subject: [PATCH 0892/1267] [PATCH] x86_64: no_iommu removal in pci-gart.c
In previous versions of pci-gart.c, no_iommu was used to determine if IOMMU was
disabled in the GART DMA mapping functions. This changed in 2.6.16 and now
gart_xxx() functions are only called if gart is enabled. Therefore, uses of
no_iommu in the GART code are no longer necessary and can be removed.
Also, it removes double deceleration of no_iommu and force_iommu in pci.h and
proto.h, by removing the deceleration in pci.h.
Lastly, end_pfn off by one error.
Tested (along with patch 1/2) on dual opteron with gart enabled, iommu=soft,
and iommu=off.

Subject: [PATCH 0897/1267] [PATCH] x86-64/i386: Use common X86_PM_TIMER option
and make it EMBEDDED
This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi
And since PM timer is needed for correct timing on a lot of systems
now (e.g. AMD dual cores) and we often get bug reports from people
who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had
this change before and it's a good thing.
I also fixed the description slightly to make this more clear.

Subject: [PATCH 0899/1267] [PATCH] x86_64: Disable ACPI blacklist by year for
now on x86-64
ACPI is initialized very early on x86-64, before the DMI code is
initialized. This means it would often discover a 0 year and then turn
off ACPI because it thought the BIOS was too old. Some systems don't
boot without ACPI so this was a problem.
I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged. For 2.6.16 let's just turn the
check off. It never made much sense anyways because there are no x86-64
systems older than 2002 or so and they generally all have working ACPI.

Subject: [PATCH 0901/1267] [PATCH] x86_64: Move the SMP time selection earlier
SMP time selection originally ran after all CPUs were brought up because
it needed to know the number of CPUs to decide if it needs an MP safe
timer or not.
This is not needed anymore because we know present CPUs early.
This fixes a couple of problems:
- apicmaintimer didn't always work because it relied on state that was
set up time_init_gtod too late.
- The output for the used timer in early kernel log was misleading
because time_init_gtod could actually change it later. Now always
print the final timer choice

Subject: [PATCH 0902/1267] [PATCH] x86_64: Better ATI timer fix
The previous experiment for using apicmaintimer on ATI systems didn't
work out very well. In particular laptops with C2/C3 support often
don't let it tick during idle, which makes it useless. There were also
some other bugs that made the apicmaintimer often not used at all.
I tried some other experiments - running timer over RTC and some other
things but they didn't really work well neither.
I rechecked the specs now and it turns out this simple change is
actually enough to avoid the double ticks on the ATI systems. We just
turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC.
I tested it on a few ATI systems and it worked there. In fact it worked
on all chipsets (NVidia, Intel, AMD, ATI) I tried it on.
According to the ACPI spec routing should always work through the
IO-APIC so I think it's the correct thing to do anyways (and most of the
old gunk in check_timer should be thrown away for x86-64).
But for 2.6.16 it's best to do a fairly minimal change:
- Use the known to be working everywhere-but-ATI IRQ0 both over 8254
and IO-APIC setup everywhere
- Except on ATI disable IRQ0 in the 8254
- Remove the code to select apicmaintimer on ATI chipsets
- Add some boot options to allow to override this (just paranoia)
In 2.6.17 I hope to switch the default over to this for everybody.

Commit 9c869edac591977314323a4eaad5f7633fca684f broke voyager again
rather subtly because it already had its own topology exporting
functions, so now each CPU gets registered twice.
I think we can actually use the generic ones, so I don't propose
reverting it. The attached should eliminate the voyager topology
functions in favour of the generic ones.
I also added a define to ensure voyager is never hotplug CPU (we don't
have the support in the SMP harness).

Subject: [PATCH 0907/1267] [SPARC64]: Make cpu_present_map available earlier.
The change to kernel/sched.c's init code to use for_each_cpu()
requires that the cpu_possible_map be setup much earlier.
Set it up via setup_arch(), constrained to NR_CPUS, and later
constrain it to max_cpus in smp_prepare_cpus().
This fixes SMP booting on sparc64.

Further investigation shows that the problem was introduced during
Alan's "TTY layer buffering revamp" patch, the amount of data to be
copied being reduced after buffer allocation. Moving the count fixup
around solves the problem.

Subject: [PATCH 0912/1267] [MIPS] SMP: Fix initialization order bug.
A recent change requires cpu_possible_map to be initialized before
smp_sched_init() but most MIPS platforms were initializing their
processors in the prom_prepare_cpus callback of smp_prepare_cpus. The
simple fix of calling prom_prepare_cpus from one of the earlier SMP
initialization hooks doesn't work well either since IPIs may require
init_IRQ() to have completed, so bit the bullet and split
prom_prepare_cpus into two initialization functions, plat_smp_setup
which is called early from setup_arch and plat_prepare_cpus called where
prom_prepare_cpus used to be called.

Subject: [PATCH 0917/1267] [IPSEC]: Kill post_input hook and do NAT-T in
esp_input directly
The only reason post_input exists at all is that it gives us the
potential to adjust the checksums incrementally in future which
we ought to do.
However, after thinking about it for a bit we can adjust the
checksums without using this post_input stuff at all. The crucial
point is that only the inner-most NAT-T SA needs to be considered
when adjusting checksums. What's more, the checksum adjustment
comes down to a single u32 due to the linearity of IP checksums.
We just happen to have a spare u32 lying around in our skb structure :)
When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum
is currently unused. All we have to do is to make that the checksum
adjustment and voila, there goes all the post_input and decap structures!
I've left in the decap data structures for now since it's intricately
woven into the sec_path stuff. We can kill them later too.

before using it
Every rerouter needs to provide a save and a reroute function, we don't
need to check for them. But we do need to check if a rerouter is registered
at all for the current family, with bridging for example packets of
unregistered families can hit nf_queue.

Subject: [PATCH 0923/1267] [NETFILTER]: Restore {ipt,ip6t,ebt}_LOG
compatibility
The nfnetlink_log infrastructure changes broke compatiblity of the LOG
targets. They currently use whatever log backend was registered first,
which means that if ipt_ULOG was loaded first, no messages will be printed
to the ring buffer anymore.
Restore compatiblity by using the old log functions by default and only use
the nf_log backend if the user explicitly said so.

Subject: [PATCH 0924/1267] [REQSK]: Don't reset rskq_defer_accept in
reqsk_queue_alloc
In 295f7324ff8d9ea58b4d3ec93b1aaa1d80e048a9 I moved defer_accept from
tcp_sock to request_queue and mistakingly reset it at reqsl_queue_alloc, causing
calls to setsockopt(TCP_DEFER_ACCEPT ) to be lost after bind, the fix is to
remove the zeroing of rskq_defer_accept from reqsl_queue_alloc.
Thanks to Alexandra N. Kossovsky <Alexandra.Kossovsky@oktetlabs.ru> for
reporting and testing the suggested fix.

Subject: [PATCH 0925/1267] via-velocity: fix memory corruption when changing
the mtu
velocity_rx_refill() only replenishes the descriptor entries which
belong to the CPU. It works great in the Rx path but the driver must
ensure that all the descriptors are freed before velocity_rx_refill()
is used in velocity_change_mtu(). The patch resets the Rx descriptors
in velocity_free_rd_ring().

Subject: [PATCH 0939/1267] [SCSI] sg: Remove aha1542 hack
Remove a hack in the sg driver that alters the total buffer
length for SG_IO commands to ensure buffers are not odd byte
lengths. This breaks on the ipr driver since it requires the
request_bufflen to equal the length specified in the cdb.
The block layer SG_IO code does not appear to have this hack.

Subject: [PATCH 0940/1267] [SCSI] fc_transport: stop creating duplicate rport
entries.
Current fc_transport consumers initially register rports
with an UNKNOWN role-state and follow-up with a call to
fc_remote_port_rolechg(). Modify code in
fc_remote_port_add() to scan the fc_host_rport_bindings()
array for consistent bindings regardless of role-type.
Original code would only scan bindings array for targets,
causing duplicate fc_remote_ports/rport-X:Y-Z entries to be
created for the yet-to-be-role-changed rports.

Subject: [PATCH 0946/1267] [PATCH] powerpc: fix dynamic PCI probe regression
Some hotplug driver functions were migrated to the kernel for use by EEH
in commit 2bf6a8fa21570f37fd1789610da30f70a05ac5e3.
Previously, the PCI Hotplug module had been changed to use the new
OFDT-based PCI probe when appropriate:
5fa80fcdca9d20d30c9ecec30d4dbff4ed93a5c6
When rpaphp_pci_config_slot() was moved from the rpaphp driver to the
new kernel function pcibios_add_pci_devices(), the OFDT-based probe
stuff was dropped. This patch restores it.

Subject: [PATCH 0947/1267] [PATCH] powerpc: vdso 64bits gettimeofday bug
A bug in the assembly code of the vdso can cause gettimeofday() to hang
or to return incorrect results. The wrong register was used to test for
pending updates of the calibration variables and to create a dependency
for subsequent loads. This fixes it.

Subject: [PATCH 0949/1267] [PATCH] powerpc/iseries: Fix double phys_to_abs bug
in htab_bolt_mapping
Before the merge I updated create_pte_mapping() to work for iSeries, by
calling iSeries_hpte_bolt_or_insert. (4c55130b2aa93370f1bf52d2304394e91cf8ee39)
Later we changed iSeries_hpte_insert to cope with the bolting case, and called
that instead from create_pte_mapping() (which was renamed to htab_bolt_mapping)
(3c726f8dee6f55e96475574e9f645327e461884c).
Unfortunately that change introduced a subtle bug, where we pass an absolute
address to iSeries_hpte_insert() where it expects a physical address. This
leads to us calling phys_to_abs() twice on the physical address, which is
seriously bogus.
This only causes a problem if the absolute address from the first translation
can be looked up again in the chunk_map, which depends on the size and layout
of memory. I've seen it fail on one box, but not others.
The minimal fix is to pass the physical address to iSeries_hpte_insert(). For
2.6.17 we should make phys_to_abs() BUG if we try to double-translate an
address.

Subject: [PATCH 0950/1267] [PATCH] cfq-iosched: slice expiry fixups
During testing of SLES10, we encountered a hang in the CFQ io scheduler.
Turns out the deferred slice expiry logic is buggy, so remove that for
now. We could be left with an idle queue that would never wake up. So
kill that logic, always expire immediately. Also fix a potential timer
race condition.
Patch looks bigger than it is, because it moves a function.

Subject: [PATCH 0954/1267] [MIPS] Initialize S-cache function pointers even on
S-cache-less CPUs.
When a CPU has no scache, the scache flushing functions currently
aren't getting initialized and the NULL pointer is eventually called
as a function. Initialize the scache flushing functions as a noop
when there's no scache.
Initial patch by me and most of the debugging done by Martin Michlmayr.

Subject: [PATCH 0956/1267] [SCSI] aha152x: fix variable use before
initialisation and other bugs
- change interface of the reset functions from Scsi_Cmnd to Scsi_Host.
- add functions with the original interface and rename the new
functions to reflect the new interface.
- call these from the pcmcia driver, thereby avoiding the need to
construct a (broken) Scsi_Cmnd from a Scsi_Host.
- just run the bh if the interrupt is from the controller and if so
ensure that it's only called once per interrupt.

Subject: [PATCH 0957/1267] [IA64] sysctl option to silence unaligned trap
warnings
Allow sysadmin to disable all warnings about userland apps
making unaligned accesses by using:
# echo 1 > /proc/sys/kernel/ignore-unaligned-usertrap
Rather than having to use prctl on a process by process basis.
Default behaivour leaves the warnings enabled.

Fix http://bugzilla.kernel.org/show_bug.cgi?id=6128
Finish morphing the "early handoff" version of the EHCI BIOS handshake over
to match the previous implementation inside the EHCI driver (except that
now we forcibly disable the SMI). The version that had been with the PCI
code was surprisingly full of bugs.

Subject: [PATCH 0966/1267] [PATCH] sky2: remove MSI support
Remove Message Signaled Interrupt support (for 2.6.16).
MSI is inherently edge-triggered and that is incompatiable (without more
work) with NAPI.
In future, will replace with smarter lockless-IRQ handling like
tg3.c

Subject: [PATCH 0967/1267] [PATCH] e1000: revert to single descriptor for
legacy receive path
A recent patch attempted to enable more efficient memory usage by using
only 2kB descriptors for jumbo frames. The method used to implement this
has since been commented upon as "illegal" and in recent kernels even
causes a BUG when receiving ip fragments while using jumbo frames.
This patch simply goes back to the way things were. We expect some
complaints due to order 3 allocations failing to come back due to this
change.

Subject: [PATCH 0970/1267] [PATCH] fuse: fix bug in negative lookup
If negative entries (nodeid == 0) were sent in reply to LOOKUP requests,
two bugs could be triggered:
- looking up a negative entry would return -EIO,
- revaildate on an entry which turned negative would send a FORGET
request with zero nodeid, which would cause an abort() in the
library.
The above would only happen if the 'negative_timeout=N' option was used,
otherwise lookups reply -ENOENT, which worked correctly.

Subject: [PATCH 0971/1267] [PATCH] drivers/mtd/redboot.c: recognise a foreign
byte sex partition table
The RedBoot boot loader writes flash partition tables containing native
byte sex 32 bit values. When booting an opposite byte sex kernel (e.g. an
LE kernel from BE RedBoot) the current MTD driver fails to handle the
partition table and therefore is unable to generate the correct partition
map for the flash.
So far as I am aware this problem is ARM specific, because only ARM
supports software change of the CPU (memory system) byte sex, however the
partition table parsing is in generic MTD code. The patch below has been
tested on NSLU2 (an IXP4XX based system) with a patch,
10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM
specific) required to make the maps/ixp4xx.c driver work with an LE kernel.
Builds of the patched system are in the 'unstable' release of OpenSlug and
UcSlugC available from www.nslu2-linux.org. These builds are BE, the
archives at www.nslu2-linux.org and www.handhelds.org (see
monotone.vanille.de) can be built LE (currently DISTRO targets
nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf,
nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested
extensively will both BE and LE systems on the NSLU2 (including swapping
between BE and LE by reflashing from both RedBoot and Linux).
The patch recognises that the FIS directory (the partition table) is
byte-reversed by examining the partition table size, which is known to be
one erase block (this is an assumption made elsewhere in redboot.c). If
the size matches the erase block after byte swapping the value then
byte-reversal is assumed, if not no further action is taken. The patched
code is fail safe; should redboot.c be changed to support a partition table
with a modified size field the test will fail and the partition table will
be assumed to have the host byte sex.
If byte-reversal is detected the patch byte swaps the remainder of the 32
bit fields in the copy of the table; this copy is then used to set up the
MTD partition map.

remove_from_swap() currently attempts to use page_lock_anon_vma to obtain
an anon_vma lock. That is not working since the page may have been
remapped via swap ptes in order to move the page.
However, do_migrate_pages() obtain the mmap_sem lock and therefore there is
a guarantee that the anonymous vma will not vanish from under us. There is
therefore no need to use page_lock_anon_vma.

Subject: [PATCH 0978/1267] [PATCH] Add mm->task_size and fix powerpc vdso
This patch adds mm->task_size to keep track of the task size of a given mm
and uses that to fix the powerpc vdso so that it uses the mm task size to
decide what pages to fault in instead of the current thread flags (which
broke when ptracing).
(akpm: I expect that mm_struct.task_size will become the way in which we
finally sort out the confusion between 32-bit processes and 32-bit mm's. It
may need tweaks, but at this stage this patch is powerpc-only.)

Subject: [PATCH 0985/1267] [PATCH] pcmcia: add id for AMB8110 PC Card
The axnet_cs driver can support the AMB8110 PC Card, so add the id for it.
In the old pcmcia-cs config file, this card is listed with the comment "not
specific enough". The last entry in the axnet_ids has the same comment.
They are disabled, and for good reason as it was originally identified by
the MANFID, and that is shared with several cards that use both the
pcnet_cs driver and axnet_cs driver. I tried my AMB8110 with pcnet_cs, and
found that it works fine, and I cannot find a reason for either, except
that the old config file recommended axnet_cs.

UML on x86-64
The check to determine which format string is appopriate for u64 and
friends works in most cases, but UML on x86_64 doesn't define CONFIG_X86_64,
so it results in screen fulls of compile-time warnings.
This patch fixes it to handle that case.

Subject: [PATCH 0991/1267] [MIPS] Use USECS_PER_SEC / HZ instead of tick_usec
in do_gettimeofday.
The 'tick_usec' is USER_HZ period in usec. do_gettimeofday() should
use kernel HZ value.
Here is a patch for MIPS. It seems m32r, m68k and sparc have same
problem though their HZ and USER_HZ are same for now.

Orphan dir recovery can deadlock with another process in
ocfs2_delete_inode() in some corner cases. Fix this by tracking recovery
state more closely and allowing it to handle inode wipes which might
deadlock.

Lucho's atomic create+open fix had a bug in the super block initialization
causing all mounts to fail. He was freeing an fcall too early. This patch
fixes that oversight.

Subject: [PATCH 1003/1267] [PATCH] v9fs: simplify fid mapping
v9fs has been plagued by an over-complicated approach trying to map Linux
dentry semantics to Plan 9 fid semantics. Our previous approach called for
aggressive flushing of the dcache resulting in several problems (including
wierd cwd behavior when running /bin/pwd).
This patch dramatically simplifies our handling of this fid management. Fids
will not be clunked as promptly, but the new approach is more functionally
correct. We now clunk un-open fids only when their dentry ref_count reaches 0
(and d_delete is called).
Another simplification is we no longer seek to match fids to the process-id or
uid of the action initiator. The uid-matching will need to be revisited when
we fix the security model.

Subject: [PATCH 1005/1267] [PATCH] time_interpolator: Use readq_relaxed()
instead of readq().
On some platforms readq performs additional work to make sure I/O is done
in a coherent way. This is not needed for time retrieval as done by the
time interpolator. So we can use readq_relaxed instead which will improve
performance.
It affects sparc64 and ia64 only. Apparently it makes a significant
difference on ia64.

Subject: [PATCH 1008/1267] [PATCH] reiserfs: fix unaligned bitmap usage
The bitmaps associated with generation numbers for directory entries
are declared as an array of ints. On some platforms, this causes alignment
exceptions.
The following patch uses the standard bitmap declaration macros to
declare the bitmaps, fixing the problem.

Subject: [PATCH 1011/1267] powerpc: Fix might-sleep warning in program check
exception handler
On 32-bit, the exception prolog for the program check exception doesn't
enable interrupts early on. If it is an illegal instruction exception,
we read the instruction in order to emulate certain instructions, and
the get_user of the instruction triggers a WARN_ON since interrupts
are still disabled. This adds a local_irq_enable() to enable
interrupts before reading the instruction.

The variable `timebase' used to transfer the current timebase value
from one cpu to the other in smp_core99_give/take_timebase was only
an unsigned long, i.e. 32 bits on 32-bit machines. It needs to be
64 bits. This makes it a u64, and fixes the issue reported by Kyle
Moffett, that the two cpus see wildly different values for the time

Subject: [PATCH 1014/1267] [PATCH] powerpc: Fix old g5 issues with windfarm
Some of the windfarm sensor modules can initialize on old machines that
don't have full windfarm support like non-dual core desktop G5s.
Unfortunately, by doing so, they would trigger a bug in their matching
algorithm causing them to attach to the wrong bus, thus triggering
issues with the i2c core and breaking the thermal driver.
This patch fixes the probing issue (so that they will work when a
windfarm port is done to these machines) and also prevents for now
windfarm to load at all on these machines that still use therm_pm72 to
avoid wasting resources.

On logically-partitioned machines the first element of the reg
property in the memory node is defined to be the "RMO" region,
i.e. the memory that the processor can access in real mode. On other
machines the first element has no special meaning, so only take it to
be the RMO region on LPAR machines.

Composite2 input
This patch adds another composite input to the Pinnacle PCTV 100i
definition which filters the chrominace signal from the luma input. This
improves video quality for Composite signals on the S-Video connector of
the card.
In addition the name string of the card is changed to include PCTV 40i
and 50i since these cards are identical.

Subject: [PATCH 1024/1267] V4L/DVB (3348): Fixed saa7134 ALSA initialization
with multiple cards
When multiple cards were installed, only the first card would have
audio initialized, because only the first position in the array parameter
defaulted to "1"
To make things worse, the "enable" parameter wasn't enabled, so there
was no workaround.

Subject: [PATCH 1027/1267] V4L/DVB (3378): Restore power on defaults of
tda9887 after tda8290 probe
The probing code for tda8290 changes the state of the tda9887 GP ports.
The patch assumes that if probing for tda8290 failed, this must be a
tda9887 and restores its power on defaults.
This should solve the module load order issue with some pinnacle cards.

Subject: [PATCH 1030/1267] V4L/DVB (3382): Fix stv0297 for qam128 on tt c1500
(saa7146)
I have a TT C1500 card (saa7146, STV0297) which had problems tuning
channels at QAM128 (like the ones in the Finnish HTV / Welho network).
A fix which seems to work perfectly so far is to change the delay for
QAM128 to the same values as for QAM256 in stv0297_set_frontend(),

PCI subsystem ID
- ELSA EX-VISION 500TV was incorrectly programmed to have the same
subsystem ID as ELSA EX-VISION 300TV, (1048:226b)
- This changeset replaces the incorrect subsystem ID (1048:226b)
with the correct one (1048:226a) for the ELSA EX-VISION 500TV.

Almost all the code for the VIA RNG is guarded with __i386__ #ifdefs,
the only exception being the enumeration of RNG types which is used to
index into the rng_vector ops array. This patch adds an ifdef around
that for consistency and since the guard makes a difference when adding
new RNG types on non-i386 hardware.

Subject: [PATCH 1040/1267] [CIFS] Always match oplock break (cache
notification) to the right tcp session when multiply mounted.
Fixes slow response when cifs client is mounted to shares on multiple
servers and oplock break occurs (usually due to attempt to multiply open a
file). When treeids on mutiple mounted shares match and we find the wrong
match first, we searched for the wrong cached files to send oplock break
response for which usually meant that no matching file was found and thus
the server would have to timeout the notification. Oplock break timeout is
about 20 seconds on some servers so this could cause significantly slower
performance on file open calls in a few cases (in particular when multiple
shares are mounted from multiple servers, tree ids match, and we have a
cached file which is later opened multiple times). This was the most
important of the bugs that was found and fixed at Connectathon
(interoperability testing event) this week.

Subject: [PATCH 1041/1267] [BRIDGE]: fix crash in STP
Bridge would crash because of uninitailized timer if STP is used and
device was inserted into a bridge before bridge was up. This got
introduced when the delayed port checking was added. Fix is to not
enable STP on port unless bridge is up.

cares (not sure about Xen) but since it generates add uevent
it should generate remove as well.

Subject: [PATCH 1049/1267] [SERIAL] Fix two bugs in parport_serial
Steinar H. Gunderson reported:
- For some reason, it detects the 9845 as a 9735 -- it appears this is
simply related to the ordering in parport_serial_pci_tbl[]. If we move
the 9845 up above the 9735, it prints out 9710:9845, but no change in
behaviour. (We didn't find out why this was the case; we left it alone
since it didn't affect our problem.)
- The card has no parallel port (at least no physical ones), yet it reports
(via its subsystem ID of 0x0014) one parallel port and four serial ports.
The probe for the parallel port fails, and the driver just aborts. Thus,
it doesn't find the serial ports.
Fix the debugging code to use dev_dbg, but don't bother displaying the
PCI ID of the detected board (that's accessible via other means.)
Also, arrange for parport_register() to return 0 even if it finds no
ports.

Subject: [PATCH 1053/1267] Add early-boot-safety check to cond_resched()
Just to be safe, we should not trigger a conditional reschedule during
the early boot sequence. We've historically done some questionable
early on, and the safety warnings in __might_sleep() are generally
turned off during that period, so there might be problems lurking.
This affects CONFIG_PREEMPT_VOLUNTARY, which takes over might_sleep() to
cause a voluntary conditional reschedule.

Subject: [PATCH 1055/1267] slab: clarify and fix calculate_slab_order()
If we triggered the 'offslab_limit' test, we would return with
cachep->gfporder incremented once too many times.
This clarifies the logic somewhat, and fixes that bug.

Subject: [PATCH 1056/1267] [PATCH] cramfs mounts provide corrupted content
since 2.6.15
Fix handling of cramfs images created by util-linux containing empty
regular files. Images created by cramfstools 1.x were ok.
Fill out inode contents in cramfs_iget5_set() instead of get_cramfs_inode()
to prevent issues if cramfs_iget5_test() is called with I_LOCK|I_NEW still
set.

Subject: [PATCH 1061/1267] [PATCH] fix next_timer_interrupt() for hrtimer
Also from Thomas Gleixner <tglx@linutronix.de>
Function next_timer_interrupt() got broken with a recent patch
6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to
hrtimer. This broke things as next_timer_interrupt() did not check hrtimer
tree for next event.
Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ,
VST) implementations, as the system can be in idle when next hrtimer event
was supposed to happen. At least ARM and S390 currently use
next_timer_interrupt().

Subject: [PATCH 1068/1267] [PATCH] numa_maps update
Change the format of numa_maps to be more compact and contain additional
information that is useful for managing and troubleshooting memory on a
NUMA system. Numa_maps can now also support huge pages.
Fixes:
1. More compact format. Only display fields if they contain additional
information.
2. Always display information for all vmas. The old numa_maps did not display
vma with no mapped entries. This was a bit confusing because page
migration removes ptes for file backed vmas. After page migration
a part of the vmas vanished.
3. Rename maxref to maxmap. This is the maximum mapcount of all the pages
in a vma and may be used as an indicator as to how many processes
may be using a certain vma.
4. Include the ability to scan over huge page vmas.
New items shown:
dirty
Number of pages in a vma that have either the dirty bit set in the
page_struct or in the pte.
file=<filename>
The file backing the pages if any
stack
Stack area
heap
Heap area
huge
Huge page area. The number of pages shows is the number of huge
pages not the regular sized pages.
swapcache
Number of pages with swap references. Must be >0 in order to
be shown.
active
Number of active pages. Only displayed if different from the number
of pages mapped.
writeback
Number of pages under writeback. Only displayed if >0.
Sample ouput of a process using huge pages:

Subject: [PATCH 1070/1267] [PATCH] ramfs needs to update directory m/ctime on
symlink
ramfs neglects to update the directory mtime and ctime fields when creating
a new symbolic link. Ramfs was modified in 2.6.15 to update these fields
when other types of entries are created. The symlink support is separate
from that other support, so that change did not cover quite all of the
possibilities.
All of the directory content manipulation entry points now seem to be
covered with respect to these time field updates.

Subject: [PATCH 1072/1267] [PATCH] smaps: shared fix
The point of the smaps "shared" is to count the number of pages that are
mapped by more than one process, according to Mauricio Lin. However, smaps
uses page_count for this, so it will return a false positive for every page
that is mapped by just that one process, which is also in pagecache or
swapcache. There are false positive situations for anonymous pages not in
swapcache as well: - page reclaim, migration - get_user_pages (eg.
direct-io, ptrace)
Use page_mapcount instead, to count the number of mappings to the page.
Use vm_normal_page so that weird things like /dev/mem aren't counted either.

Subject: [PATCH 1076/1267] [TG3]: Add DMA address workaround
Add DMA workaround for chips that do not support full 64-bit DMA
addresses.
5714, 5715, and 5780 chips only support DMA addresses less than 40
bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so
that pci_map_xxx() calls will map the DMA address below 40 bits if
necessary. On 64-bit systems without IOMMU, set the dma_mask to
64-bit and check for DMA addresses exceeding the limit in
tg3_start_xmit().
5788 only supports 32-bit DMA so need to set the mask appropriately
also.
Thanks to Chris Elmquist at SGI for reporting and helping to debug
the problem on 5714.
Thanks to David Miller for explaining the HIGHMEM and DMA stuff.

Subject: [PATCH 1077/1267] [ARM] 3352/1: DSB required for the completion of a
TLB maintenance operation
Patch from Catalin Marinas
Chapter B2.7.3 in the latest ARM ARM (with v6 information) states that
the completion of a TLB maintenance operation is only guaranteed by
the execution of a DSB (Data Syncronization Barrier, formerly Data
Write Barrier or Drain Write Buffer).
Note that a DSB is only needed in the flush_tlb_kernel_* functions
since the completion is guaranteed by a mode change (i.e. switching
back to user mode) for the flush_tlb_user_* functions.

Increase the severity to KERN_ERR, for the initial
message (and also add the physical address to this

KERN_DEBUG, but increase the severity when isolation
fails to KERN_CRIT.

Subject: [PATCH 1083/1267] [IA64] gensparse_defconfig: turn on PNPACPI
Turn on CONFIG_PNPACPI. I recently removed 8250_acpi.c. All devices
previously claimed by 8250_acpi.c should now be claimed by 8250_pnp.c.
This depends on having CONFIG_PNPACPI so ACPI devices show up as PNP
devices.
All other ia64 defconfigs either have CONFIG_PNPACPI already, or
don't have 8250 support turned on at all.

Subject: [PATCH 1087/1267] powerpc: Fix various syscall/signal/swapcontext
bugs
A careful reading of the recent changes to the system call entry/exit
paths revealed several problems, plus some things that could be
simplified and improved:
* 32-bit wasn't testing the _TIF_NOERROR bit in the syscall fast exit
path, so it was only doing anything with it once it saw some other
bit being set. In other words, the noerror behaviour would apply to
the next system call where we had to reschedule or deliver a signal,
which is not necessarily the current system call.
* 32-bit wasn't doing the call to ptrace_notify in the syscall exit
path when the _TIF_SINGLESTEP bit was set.
* _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and
_TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set
by system calls. I took it out of _TIF_USER_WORK_MASK.
* On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers
to be restored (unless perhaps a signal was delivered or the syscall
was traced or single-stepped). Thus the non-volatile registers
weren't restored on exit from a signal handler. We probably got
away with it mostly because signal handlers written in C wouldn't
alter the non-volatile registers.
* On 32-bit I simplified the code and made it more like 64-bit by
making the syscall exit path jump to ret_from_except to handle
preemption and signal delivery.
* 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was
set - but I think because of that 32-bit was actually restoring the
non-volatile registers on exit from a signal handler.
* I changed the order of enabling interrupts and saving the
non-volatile registers before calling do_syscall_trace_leave; now we
enable interrupts first.

Subject: [PATCH 1094/1267] [PATCH] serial core: work around sub-driver bugs
We're presently getting oopses because Bluetooth (and possibly other) drivers
are calling core functions after things have been shut down.
So rather than oopsing, let's drop a warning then take avoiding action, so the
machine survives. Once all the sub-drivers are fixed up we can remove the
take-avoiding-action part.

Subject: [PATCH 1096/1267] [PATCH] udf: fix uid/gid options and add
uid/gid=ignore and forget options
Fix a bug in udf where it would write uid/gid = 0 to the disk for files
owned by the id given with the uid=/gid= mount options. It also adds 4 new
mount options: uid/gid=forget and uid/gid=ignore. Without any options the
id in core and on disk always match. Giving uid/gid=nnn specifies a
default ID to be used in core when the on disk ID is -1. uid/gid=ignore
forces the in core ID to allways be used no matter what the on disk ID is.
uid/gid=forget forces the on disk ID to always be written out as -1.
The use of these options allows you to override ownerships on a disk or
disable ownwership information from being written, allowing the media to be
used portably between different computers and possibly different users
without permissions issues that would require root to correct.

Fix i386 nmi_watchdog that does not meet watchdog timeout condition. It
does not hit die_nmi when it should be triggered, because the current
nmi_watchdog_tick in arch/i386/kernel/nmi.c never count up alert_counter
like this:
void nmi_watchdog_tick (struct pt_regs * regs) {
if (last_irq_sums[cpu] == sum) {
alert_counter[cpu]++; <- count up alert_counter, but
if (alert_counter[cpu] == 5*nmi_hz)
die_nmi(regs, "NMI Watchdog detected LOCKUP");
alert_counter[cpu] = 0; <- reset alert_counter
This patch changes it back to the previous and working version.
This was found and originally written by Kohta NAKASHIMA.

Subject: [PATCH 1101/1267] [PATCH] rcu batch tuning
This patch adds new tunables for RCU queue and finished batches. There are
two types of controls - number of completed RCU updates invoked in a batch
(blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark,
qlowmark).
By default, the per-cpu batch limit is set to a small value. If the input
RCU rate exceeds the high watermark, we do two things - force quiescent
state on all cpus and set the batch limit of the CPU to INTMAX. Setting
batch limit to INTMAX forces all finished RCUs to be processed in one shot.
If we have more than INTMAX RCUs queued up, then we have bigger problems
anyway. Once the incoming queued RCUs fall below the low watermark, the
batch limit is set to the default.

Subject: [PATCH 1102/1267] [PATCH] fix file counting
I have benchmarked this on an x86_64 NUMA system and see no significant
performance difference on kernbench. Tested on both x86_64 and powerpc.
The way we do file struct accounting is not very suitable for batched
freeing. For scalability reasons, file accounting was
constructor/destructor based. This meant that nr_files was decremented
only when the object was removed from the slab cache. This is susceptible
to slab fragmentation. With RCU based file structure, consequent batched
freeing and a test program like Serge's, we just speed this up and end up
with a very fragmented slab -
llm22:~ # cat /proc/sys/fs/file-nr
587730 0 758844
At the same time, I see only a 2000+ objects in filp cache. The following
patch I fixes this problem.
This patch changes the file counting by removing the filp_count_lock.
Instead we use a separate percpu counter, nr_files, for now and all
accesses to it are through get_nr_files() api. In the sysctl handler for
nr_files, we populate files_stat.nr_files before returning to user.
Counting files as an when they are created and destroyed (as opposed to
inside slab) allows us to correctly count open files with RCU.

Subject: [PATCH 1106/1267] [PATCH] s390: dasd partition detection
DASD allows to open a device as soon as gendisk is registered, which means the
device is a fake device (capacity=0) and we do know nothing about blocksize
and partitions at that point of time. In case the device is opened by
someone, the bdev and inode creation is done with the fake device info and the
following partition detection code is just using the wrong data.
To avoid this modify the DASD state machine to make sure that the open is
rejected until the device analysis is either finished or an unformatted device
was detected.

While testing kexec and kdump we hit problems where the new kernel would
freeze or instantly reboot. The easiest way to trigger it was to kexec a
kernel compiled for CONFIG_M586 on an athlon cpu. Compiling for CONFIG_MK7
instead would work fine.
The patch fixes a few problems with the kexec inline asm.

Subject: [PATCH 1114/1267] [IA64] Fix race in the accessed/dirty bit handlers
A pte may be zapped by the swapper, exiting process, unmapping or page
migration while the accessed or dirty bit handers are about to run. In that
case the accessed bit or dirty is set on an zeroed pte which leads the VM to
conclude that this is a swap pte. This may lead to
- Messages from the vm like
swap_free: Bad swap file entry 4000000000000000
- Processes being aborted
swap_dup: Bad swap file entry 4000000000000000
VM: killing process ....
Page migration is particular suitable for the creation of this race since
it needs to remove and restore page table entries.
The fix here is to check for the present bit and simply not update
the pte if the page is not present anymore. If the page is not present
then the fault handler should run next which will take care of the problem
by bringing the page back and then mark the page dirty or move it onto the
active list.

A recent change to compat. dev_ifconf() in fs/compat_ioctl.c
causes ifconf data to be truncated 1 entry too early when copying it
to userspace. The correct amount of data (length) is returned,
but the final entry is empty (zero, not filled in).
The for-loop 'i' check should use <= to allow the final struct
ifreq32 to be copied. I also used the ifconf-corruption program
in kernel bugzilla #4746 to make sure that this change does not
re-introduce the corruption.

Subject: [PATCH 1116/1267] [PATCH] i386: port ATI timer fix from x86_64 to
i386 II
ATI chipsets tend to generate double timer interrupts for the local APIC
timer when both the 8254 and the IO-APIC timer pins are enabled. This is
because they route it to both and the result is anded together and the CPU
ends up processing it twice.
This patch changes check_timer to disable the 8254 routing for interrupt 0.
I think it would be safe on all chipsets actually (i tested it on a couple
and it worked everywhere) and Windows seems to do it in a similar way, but
to be conservative this patch only enables this mode on ATI (and adds
options to enable/disable too)
Ported over from a similar x86-64 change.
I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but
tweaked it a bit to work even without ACPI.
Inspired by a patch from Chuck Ebbert, but redone.

Subject: [PATCH 1117/1267] [PATCH] block: disable block layer bouncing for
most memory on 64bit systems
The low level PCI DMA mapping functions should handle it in most cases.
This should fix problems with depleting the DMA zone early. The old
code used precious GFP_DMA memory in many cases where it was not needed.

At times gcc will place bits of __exit functions into .rodata. If
compiled into the kernle itself we used to discard .exit.text - but
not the bits left in .rodata. While harmless this did at times result
in a large number of warnings. So until gcc fixes this, discard
.exit.text at runtime.

Subject: [PATCH 1132/1267] [SCSI] zfcp: fix device registration issues
The patch fixes following issues:
(1) Replace scsi_add_device with scsi_scan_target.
(Thus the rport instead of the scsi_host becomes parent of a
scsi_target again.)
(2) Avoid scsi_device allocation during registration of an remote port.
(Would be done during fc_scsi_scan_rport.)
(3) Fix queuecommand behaviour when an zfcp unit is blocked.
(Call scsi_done with DID_NO_CONNECT instead of returning
SCSI_MLQUEUE_DEVICE_BUSY otherwise we might end up waiting
for completion in blk_execute_rq for ever.)

Subject: [PATCH 1133/1267] [PATCH] page_add_file_rmap(): remove BUG_ON()s
Remove two early-development BUG_ONs from page_add_file_rmap.
The pfn_valid test (originally useful for checking that nobody passed an
artificial struct page) comes too late, since we already have the struct
page.
The PageAnon test (useful when anon was first distinguished from file rmap)
prevents ->nopage implementations from reusing ->mapping, which would
otherwise be available.

smi_data_buf_free() references dcdbas_pdev when calling
dma_free_coherent(). In dcdbas_exit(), smi_data_buf_free() is called after
platform_device_unregister(dcdbas_pdev).
This patch moves platform_device_unregister(dcdbas_pdev) after
smi_data_buf_free() in dcdbas_exit().

Subject: [PATCH 1143/1267] [PATCH] s390: Increase spinlock retry code
performance
Currently the code tries up to spin_retry times to grab a lock using the cs
instruction. The cs instruction has exclusive access to a memory region
and therefore invalidates the appropiate cache line of all other cpus. If
there is contention on a lock this leads to cache line trashing. This can
be avoided if we first check wether a cs instruction is likely to succeed
before the instruction gets actually executed.

fix
When pages are onlined, not only zone->present_pages but also
pgdat->node_present_pages should be refreshed.
This parameter is used to show information at
/sys/device/system/node/nodeX/meminfo via si_meminfo_node().
So, it shows strange value for MemUsed which is calculated
(node_present_pages - all zones free pages).

Subject: [PATCH 1148/1267] [PATCH] slab: Node rotor for freeing alien caches
and remote per cpu pages.
The cache reaper currently tries to free all alien caches and all remote
per cpu pages in each pass of cache_reap. For a machines with large number
of nodes (such as Altix) this may lead to sporadic delays of around ~10ms.
Interrupts are disabled while reclaiming creating unacceptable delays.
This patch changes that behavior by adding a per cpu reap_node variable.
Instead of attempting to free all caches, we free only one alien cache and
the per cpu pages from one remote node. That reduces the time spend in
cache_reap. However, doing so will lengthen the time it takes to
completely drain all remote per cpu pagesets and all alien caches. The
time needed will grow with the number of nodes in the system. All caches
are drained when they overflow their respective capacity. So the drawback
here is only that a bit of memory may be wasted for awhile longer.
Details:
1. Rename drain_remote_pages to drain_node_pages to allow the specification
of the node to drain of pcp pages.
2. Add additional functions init_reap_node, next_reap_node for NUMA
that manage a per cpu reap_node counter.
3. Add a reap_alien function that reaps only from the current reap_node.
For us this seems to be a critical issue. Holdoffs of an average of ~7ms
cause some HPC benchmarks to slow down significantly. F.e. NAS parallel
slows down dramatically. NAS parallel has a 12-16 seconds runtime w/o rotor
compared to 5.8 secs with the rotor patches. It gets down to 5.05 secs with
the additional interrupt holdoff reductions.

invalidation problem
Patch from Catalin Marinas
ARM1136 erratum 371025 (category 2) specifies that, under rare
conditions, an invalidate I-cache by MVA (line or range) operation can
fail to invalidate a cache line. The recommended workaround is to
either invalidate the entire I-cache or invalidate the range by
set/way rather than MVA.
Note that for a 16K cache size, invalidating a 4K page by set/way is
equivalent to invalidating the entire I-cache.

.kernelrelease
Rebuilding a previously built tree while using make's -j option from
time to time results in the version.h check running at the same time as
the updating of .kernelrelease, resulting in UTS_RELEASE remaining an
empty string (and as a side effect causing the entire kernel to be
rebuilt).

Subject: [PATCH 1154/1267] [PATCH] ext3: ext3_symlink should use GFP_NOFS
allocations inside
This patch fixes illegal __GFP_FS allocation inside ext3 transaction in
ext3_symlink(). Such allocation may re-enter ext3 code from
try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal
handle in task_struct and, hence, is not reentrable.
This bug led to "Assertion failure in journal_dirty_metadata()" messages.

Subject: [PATCH 1155/1267] [PATCH] ext3: fix nobh mode for chattr +j inodes
One can do "chattr +j" on a file to change its journalling mode. Fix
writeback mode with "nobh" handling for it.
Even though, we mount ext3 filesystem in writeback mode with "nobh" option,
some one can do "chattr +j" on a single file to force it to do journalled
mode. In order to do journaling, ext3_block_truncate_page() need to
fallback to default case of creating buffers and adding them to transaction
etc.

Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all
agree are very much wrong. These files shouldn't become part of the ABI by
the 2.6.16 release, so I rather have this minimal patch merged to disable
them for now, the real fix can then come during the 2.6.17 devel window.

Subject: [PATCH 1159/1267] [PATCH] remove __put_task_struct_cb export again
The patch '[PATCH] RCU signal handling' [1] added an export for
__put_task_struct_cb, a put_task_struct helper newly introduced in that
patch. But the put_task_struct couldn't be used modular previously as
__put_task_struct wasn't exported. There are not callers of it in modular
code, and it shouldn't be exported because we don't want drivers to hold
references to task_structs.
This patch removes the export and folds __put_task_struct into
__put_task_struct_cb as there's no other caller.

Subject: [PATCH 1173/1267] [PATCH] Wrong return value corrupts free object in
e1000 driver
For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT
instead of one of the NETDEV_TX_* error codes. In fact, it frees up
the SKB before returning this. This makes the queueing layer think
the packet should be requeued and subsequently we corrupt a freed
object.

Subject: [PATCH 1174/1267] [PATCH] dl2k: DMA freeing error
This patch fixes an error in the dl2k driver's DMA mapping/unmapping.
The adapter uses the upper 16bits of the DMA address for the buffer
size. However, this is not masked off when referencing the DMA
address, and can lead to errors by trying to free a DMA address out of
range.
Thanks,
Jon

Subject: [PATCH 1193/1267] [PATCH] x86-64: Fix up handling of non canonical
user RIPs
EM64T CPUs have somewhat weird error reporting for non canonical RIPs in
SYSRET.
We can't handle any exceptions there because the exception handler would
end up running on the user stack which is unsafe.
To avoid problems any code that might end up with a user touched pt_regs
should return using int_ret_from_syscall. int_ret_from_syscall ends up
using IRET, which allows safe exceptions.

Subject: [PATCH 1199/1267] [PATCH] Fix sigaltstack corruption among cloned
threads
This patch fixes alternate signal stack corruption among cloned threads
with CLONE_SIGHAND (and CLONE_VM) for linux-2.6.16-rc6.
The value of alternate signal stack is currently inherited after a call of
clone(... CLONE_SIGHAND | CLONE_VM). But if sigaltstack is set by a
parent thread, and then if multiple cloned child threads (+ parent threads)
call signal handler at the same time, some threads may be conflicted -
because they share to use the same alternative signal stack region.
Finally they get sigsegv. It's an undesirable race condition. Note that
child threads created from NPTL pthread_create() also hit this conflict
when the parent thread uses sigaltstack, without my patch.
To fix this problem, this patch clears the child threads' sigaltstack
information like exec(). This behavior follows the SUSv3 specification.
In SUSv3, pthread_create() says "The alternate stack shall not be inherited
(when new threads are initialized)". It means that sigaltstack should be
cleared when sigaltstack memory space is shared by cloned threads with
CLONE_SIGHAND.
Note that I chose "if (clone_flags & CLONE_SIGHAND)" line because:
- If clone_flags line is not existed, fork() does not inherit sigaltstack.
- CLONE_VM is another choice, but vfork() does not inherit sigaltstack.
- CLONE_SIGHAND implies CLONE_VM, and it looks suitable.
- CLONE_THREAD is another candidate, and includes CLONE_SIGHAND + CLONE_VM,
but this flag has a bit different semantics.
I decided to use CLONE_SIGHAND.
[ Changed to test for CLONE_VM && !CLONE_VFORK after discussion --Linus ]

Subject: [PATCH 1200/1267] [PATCH] NFS: Fix a potential panic in O_DIRECT
Based on an original patch by Mike O'Connor and Greg Banks of SGI.
Mike states:
A normal user can panic an NFS client and cause a local DoS with
'judicious'(?) use of O_DIRECT. Any O_DIRECT write to an NFS file where the
user buffer starts with a valid mapped page and contains an unmapped page,
will crash in this way. I haven't followed the code, but O_DIRECT reads with
similar user buffers will probably also crash albeit in different ways.
Details: when nfs_get_user_pages() calls get_user_pages(), it detects and
correctly handles get_user_pages() returning an error, which happens if the
first page covered by the user buffer's address range is unmapped. However,
if the first page is mapped but some subsequent page isn't, get_user_pages()
will return a positive number which is less than the number of pages requested
(this behaviour is sort of analagous to a short write() call and appears to be
intentional). nfs_get_user_pages() doesn't detect this and hands off the
array of pages (whose last few elements are random rubbish from the newly
allocated array memory) to it's caller, whence they go to
nfs_direct_write_seg(), which then totally ignores the nr_pages it's given,
and calculates its own idea of how many pages are in the array from the user
buffer length. Needless to say, when it comes to transmit those uninitialised
page* pointers, we see a crash in the network stack.

- Disable the EDAC sysfs code. The sysfs interface that EDAC presents to
user space needs more thought, and is likely to change substantially.
Therefore disable it for now so users don't start depending on it in its
current form.
- Disable the default behavior of calling panic() when an uncorrectible
error is detected (since for now, there is no sysfs interface that allows
the user to configure this behavior).

Subject: [PATCH 1209/1267] Fix a direct I/O locking issue revealed by the new
mutex code. Affects only XFS (i.e. DIO_OWN_LOCKING case) - currently it is
not possible to get i_mutex locking correct when using DIO_OWN direct I/O
locking in a filesystem due to indeterminism in the possible return
code/lock/unlock combinations. This can cause a direct read to attempt a
double i_mutex unlock inside XFS.
We're now ensuring __blockdev_direct_IO always exits with the
inode i_mutex (still) held for a direct reader.
Tested with the three different locking modes (via direct block
device access, ext3 and XFS) - both reading and writing; cannot
find any regressions resulting from this change, and it clearly
fixes the mutex_unlock warning originally reported here:

Subject: [PATCH 1211/1267] [PATCH] page migration: fail if page is in a vma
flagged VM_LOCKED
page migration currently simply retries a couple of times if try_to_unmap()
fails without inspecting the return code.
However, SWAP_FAIL indicates that the page is in a vma that has the
VM_LOCKED flag set (if ignore_refs ==1). We can check for that return code
and avoid retrying the migration.
migrate_page_remove_references() now needs to return a reason why the
failure occured. So switch migrate_page_remove_references to use -Exx
style error messages.

+ Reservation of pages could be avoided by having a special type of swap

+ that this process has the only reference to that page.

It seems that setting scheduling policy and priorities is also the kind of
thing that might be performed in apps that also use the NUMA API, so it
would seem consistent to use CAP_SYS_NICE for NUMA also.
So use CAP_SYS_NICE for controlling migration permissions.

Subject: [PATCH 1225/1267] [PATCH] Fix ext2 readdir f_pos re-validation logic
This fixes not one, but _two_, silly (but admittedly hard to hit) bugs
in the ext2 filesystem "readdir()" function. It also cleans up the code
to avoid the unnecessary goto mess.
The bugs were related to re-valiating the f_pos value after somebody had
either done an "lseek()" on the directory to an invalid offset, or when
the offset had become invalid due to a file being unlinked in the
directory. The code would not only set the f_version too eagerly, it
would also not update f_pos appropriately for when the offset fixup took
place.
When that happened, we'd occasionally subsequently fail the readdir()
even when we shouldn't (no real harm done, but an ugly printk, and
obviously you would end up not necessarily seeing all entries).
Thanks to Masoud Sharbiani <masouds@google.com> who noticed the problem
and had a test-case for it, and also fixed up a thinko in the first
version of this patch.

Subject: [PATCH 1226/1267] powerpc: Fix problem with time going backwards
The recent changes to keep gettimeofday in sync with xtime had the side
effect that it was occasionally possible for the time reported by
gettimeofday to go back by a microsecond. There were two reasons:
(1) when we recalculated the offsets used by gettimeofday every 2^31
timebase ticks, we lost an accumulated fractional microsecond, and
(2) because the update is done some time after the notional start of
jiffy, if ntp is slowing the clock, it is possible to see time go backwards
when the timebase factor gets reduced.
This fixes it by (a) slowing the gettimeofday clock by about 1us in
2^31 timebase ticks (a factor of less than 1 in 3.7 million), and (b)
adjusting the timebase offsets in the rare case that the gettimeofday
result could possibly go backwards (i.e. when ntp is slowing the clock
and the timer interrupt is late). In this case the adjustment will
reduce to zero eventually because of (a).

Subject: [PATCH 1233/1267] [PATCH] powerpc: properly configure DDR/P5IOC
children devs
The dynamic add path for PCI Host Bridges can fail to configure children
adapters under P5IOC controllers. It fails to properly fixup bus/device
resources, and it fails to properly enable EEH. Both of these steps
need to occur before any children devices are enabled in
pci_bus_add_devices().

when setting this pointer is not enough. We also need
a memory barrier to ensure the initialization is seen first.
Use rcu_assign_pointer as it does this for us, and clearly
documents that we are setting an rcu readable pointer.

Bryce reported a bug wherein offlining CPU0 (on x86 box) and then
subsequently onlining it resulted in a lockup.
On x86, CPU0 is never offlined. The subsequent attempt to online CPU0
doesn't take that into account. It actually tries to bootup the already
booted CPU. Following patch fixes the problem (as acknowledged by Bryce).
Please consider for inclusion in 2.6.16.

Subject: [PATCH 1243/1267] [PATCH] dm stripe: Fix bounds
The dm-stripe target currently does not enforce that the size of a stripe
device be a multiple of the chunk-size. Under certain conditions, this can
lead to I/O requests going off the end of an underlying device. This
test-case shows one example.
echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0
echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1
echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \
dmsetup create stripe0
dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k
This will produce the output:
dd: writing '/dev/mapper/stripe0': Input/output error
97+0 records in
96+0 records out
And in the kernel log will be:
attempt to access beyond end of device
dm-0: rw=0, want=104, limit=100
The patch will check that the table size is a multiple of the stripe
chunk-size when the table is created, which will prevent the above striped
device from being created.
This should not affect tools like LVM or EVMS, since in all the cases I can
think of, striped devices are always created with the sizes being a
multiple of the chunk-size.
The size of a stripe device must be a multiple of its chunk-size.
(akpm: that typecast is quite gratuitous)

Subject: [PATCH 1246/1267] [PATCH] kbuild: fix buffer overflow in modpost
Jiri Benc <jbenc@suse.cz> reported that modpost would stop with SIGABRT if
used with long filepaths.
The error looked like:
> Building modules, stage 2.
> MODPOST
> *** glibc detected *** scripts/mod/modpost: realloc(): invalid next size:
+0x0809f588 ***
> [...]
Fix this by allocating at least the required memory + SZ bytes each time.
Before we sometimes ended up allocating too little memory resuting in the
glibc detected bug above. Based on patch originally submitted by: Jiri

Subject: [PATCH 1247/1267] [PATCH] fix free swap cache latency
Lee Revell reported 28ms latency when process with lots of swapped memory
exits.
2.6.15 introduced a latency regression when unmapping: in accounting the
zap_work latency breaker, pte_none counted 1, pte_present PAGE_SIZE, but a
swap entry counted nothing at all. We think of pages present as the slow
case, but Lee's trace shows that free_swap_and_cache's radix tree lookup
can make a lot of work - and we could have been doing it many thousands of
times without a latency break.
Move the zap_work update up to account swap entries like pages present.
This does account non-linear pte_file entries, and unmap_mapping_range
skipping over swap entries, by the same amount even though they're quick:
but neither of those cases deserves complicating the code (and they're
treated no worse than they were in 2.6.14).

Subject: [PATCH 1255/1267] [MIPS] Work around bad code generation for
<asm/io.h>.
If a call to set_io_port_base() was being followed by usage of
mips_io_port_base in the same function gcc was possibly using the old
value due to some clever abuse of const. Adding a barrier will keep
the optimization and result in correct code with latest gcc.

Subject: [PATCH 1259/1267] [MIPS] Sibyte: Fix race in sb1250_gettimeoffset().
From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>:
sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining
value, however once this counter reaches 0 and the interrupt is raised,
it immediately resets and begins to count down again.
If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after
the timer has reset but prior to cpu 0 processing the interrupt and
taking write_seqlock() in timer_interrupt() it will return a full value
(or close to it) causing time to jump backwards 1ms. Once cpu 0 handles
the interrupt and timer_interrupt() gets far enough along it will jump
forward 1ms.
Fix this problem by implementing mips_hpt_*() on sb1250 using a spare
timer unrelated to the existing periodic interrupt timers. It runs at
1Mhz with a full 23bit counter. This eliminated the custom
do_gettimeoffset() for sb1250 and allowed use of the generic
fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

Subject: [PATCH 1263/1267] [PATCH] Kconfig: swap VIDEO_CX88_ALSA and
VIDEO_CX88_DVB
VIDEO_CX88_ALSA should not be between VIDEO_CX88_DVB and
VIDEO_CX88_DVB_ALL_FRONTENDS
When cx88-alsa was added to cx88/Kconfig, it was added in between
VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS. This caused
undesireable effects to the appearance of the menu options in
menuconfig.
This fix reorders cx88-alsa and cx88-dvb in Kconfig, to match saa7134,
and restore the correct menuconfig appearance.

Subject: [PATCH 1264/1267] [AX.25]: Fix potencial memory hole.
If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
(or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
through the switch statement without calling ax25_send_iframe() or any
other function that would eventually free skbn thus leaking the packet.
Fix by restricting the sysctl inferface to allow only actually supported
AX.25 dialects.
The system administration mistake needed for this to happen is rather
unlikely, so this is an uncritical hole.
Coverity #651.

Subject: [PATCH 1265/1267] [TG3]: 40-bit DMA workaround part 2
The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.
For example, some 4-port card or mother board designs have 5704 behind
the 5714.
All devices behind the EPB require the 40-bit DMA workaround.
Thanks to Chris Elmquist again for reporting the problem and testing
the patch.
