Subject[patch 0/2] Fixing AMD cmpxchg "missing lfence" mess

I've prepared this patch, which applies on 2.6.30-rc2. It's an attempt to make
the kernel work around AMD's bug regarding missing lfence in the sync; cmpxchg

The first patch is a alternative.h cleanup, and the second patch implements the
fixup using alternatives.

Indeed, this only makes the kernel aware of the bug. Userland will still have to
be taught to use such lfence too.
