Comment 16 for bug 248509

I took a quick look at these patches, and they look entirely reasonable. The only question I have concerns the set_bit(X86_FEATURE_{L,M}FENCE_RDTSC, &c->x86_capability); don't we have to protect that by first checking if sse2 is enabled? Upstream that's done with the "cpu_has_xmm2" check, but since RHEL-5 doesn't have that, we'd have to do something a little more primitive. Or am I missing something?
