I'll do this for the whole patchset.  Stay tuned for the resubmit.

Could you incorporate Segher's patch to turn atomic_{read,set} into
asm on powerpc?  Segher claims that using asm is really the only
reliable way to ensure that gcc does what we want, and he seems to
have a point.

Paul.

I haven't seen a patch yet.  I'm going to resubmit with inline volatile-cast
atomic[64]_[read|set] on all architectures as a reference point, and if anyone
wants to go and implement some of them in assembly, that's between them and
the relevant arch maintainers.  I have no problem with (someone else) doing it
in assembly.  I just don't think it's necessary and won't let it hold up the
effort to get consistent behavior on all architectures.
