Pull misc perf fixes from Ingo Molnar:

 - Require group events for branch counter groups and
   PEBS counter snapshotting groups to be x86 events.

 - Fix the handling of counter-snapshotting of non-precise
   events, where counter values may move backwards a bit,
   temporarily, confusing the code.

 - Restrict perf/KVM PEBS to guest-owned events.
