Subject: 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.

Subject: cpumask: mm_cpumask for accessing the struct mm_struct's cpu_vm_mask.

This allows us to change the representation (to a dangling bitmap or
cpumask_var_t) without breaking all the callers: they can use
mm_cpumask() now and won't see a difference as the changes roll into
