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
