[ Upstream commit f38ce0209ab4553906b44bd1159e35c740a84161 ]

small_const_nbits is defined in asm-generic/bitsperlong.h which
bitmap.h uses but doesn't include causing build failures in some build
systems. Add the missing #include.

Note the bitmap.h in tools has diverged from that of the kernel, so no
changes are made there.
