Somewhat speculatively applied to kvm-x86 pmu. I'd really like to get a thumbs
up that I didn't break anything, but I'm OOO later this week and want to get
this into linux-next before I go offline. Holler if something is broken, this
is the only thing sitting in "pmu" so it should be easy to massage if necessary.

Thanks!
