x86/perf: Use RET0 as default for guest_get_msrs to handle "no PMU" case
(2021-03-10 16:45:09 +0100)
----------------------------------------------------------------
- Make sure PMU internal buffers are flushed for per-CPU events too and
properly handle PID/TID for large PEBS.
- Handle the case properly when there's no PMU and therefore return an
empty list of perf MSRs for VMX to switch instead of reading random
garbage from the stack.
