    Impact: reduce text size
    bitmap_zero et al have a fastpath for nbits <= BITS_PER_LONG, but this
    should really only apply where the nbits is known at compile time.
    This only saves about 1200 bytes on an allyesconfig kernel, but with
    cpumasks going variable that number will increase.
