Hi all-

Vince found a bug in our CR4.PCE handling.  While investigating, I
found what looked like another bug but actually wasn't.

Here's a fix for the bug (cc'd to stable) and a comment and lockdep
annotation for why the other non-bug isn't actually a bug.

Andy Lutomirski (2):
  x86/perf: Fix CR4.PCE propagation to use active_mm instead of mm
  x86/perf: Clarify why x86_pmu_event_mapped() isn't racy
