[PATCH v5 0/5] x86: faster smp_mb()+documentation tweaks
mb() typically uses mfence on modern x86, but a micro-benchmark shows that it's
2 to 3 times slower than lock; addl that we use on older CPUs.
So we really should use the locked variant everywhere, except that intel manual
says that clflush is only ordered by mfence, so we can't.
Note: some callers of clflush seems to assume sfence will
order it, so there could be existing bugs around
