After moving gfp flags to a separate header, it's possible to move some
cpumask allocators into headers, and avoid creating real functions.

After this patch, only alloc/free functions are still in c-file, because
moving them causes multiple circular dependencies between mm and
cpumask. I'll get back later to it.
