Sometimes I am thinking that maybe ARCH_HAS_* has some benefits:

HAVE_* for those kernel-wide and general capabilities
ARCH_HAS_* for those ARM machine-class specific capabilities?

So to make things a bit more clear? If ARCH_HAS_* is widely adopted
on architectures other than ARM, maybe we can then switch that name
to HAVE_*?
