All of this HAVE_ARCH_xxx stuff gave Linus heartburn a few weeks ago,
and you're massively increasing its proliferation.

How about putting each class of bitop into its own header file in
asm-generic, and getting the arches that need each one to include the
specific files it needs in its own bitops.h header?

For example, the hweight stuff would go into
asm-generic/bitops-hweight.h, and then asm-foo/bitops.h would just use

#include <asm-generic/bitops-hweight.h>

or else define its own if it didn't need the generic versions.
