Looks fine to me, but we're going to get some truly horrible conflicts
in -next.

I'm open to suggestions on the best way to handle this, but one way
would be:

  1. Duplicate all the #defines privately in KVM (queue via kvm tree)
  2. Rebase this patch onto my perf/updates branch [1] (queue via me)
  3. Patch at -rc1 dropping the #defines from (1) and moving to the new
     perf_event.h stuff

Thoughts?
