Subject: [PATCH 0/4] perf vendor events arm64: AmpereOne: Core PMU event update and metrics

AmpereOne Core PMU documentation had unsupported events listed, which have
been removed since. In addition, certain STALL_* events have a bug and,
thus, the errata number is added for reference. Finally, metrics are added
for AmpereOne.

Ilkka Koskinen (4):
  perf vendor events arm64: Remove L1D_CACHE_LMISS from AmpereOne list
  perf vendor events arm64: AmpereOne: Mark affected STALL_* events
    impacted by errata
  perf vendor events arm64: Add AmpereOne metrics
  perf vendor events arm64: AmpereOne: Remove unsupported events
