This is blocking some patches from getting included (e.g.  the
CPUID[0xB] patch from Radim), so I'm submitting Igor's RFC as
[PATCH].

I will add it to my x86-next queue so I can queue x86 patches
that depend on it. But I plan to wait until it gets merged
through the PC tree and rebase before sending a x86 pull request.
