Sure the tail of cpu.c seems to have various other cpumask gunk in
already so it fits there. The other alternative would've been
lib/bitmap.c since that's where the various bitmap printf
implementations live.

You could make it bitmap_copy_to_buf() I suppose, and then have a
cpumask inline wrapper, to be fully consistent with the rest of the
implementations.
