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.
