Subject: [PATCH] cpumask: tsk_cpumask for accessing the struct task_struct's
cpus_allowed.
This allows us to change the representation (to a dangling bitmap or
cpumask_var_t) without breaking all the callers: they can use
tsk_cpumask() now and won't see a difference as the changes roll into
linux-next.
