# Merge: 836d7f0572ca c8e2fe13d1d1
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'perf_urgent_for_v5.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull perf fixes from Borislav Petkov:
#     
#      - 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.
