[PATCH] Introduce new cpu_mask APIs

[Stephen Rothwell]

In linux-next there is a commit ("x86: Add performance variants of cpumask
operators") which, as part of the 4096 cpu support work adds some new
APIs for dealing with cpu masks.  Add thrivial versions of these now
so that subsystems can update in a timely manner and avoid conflicts in
linux-next and the next merge window.
