Subject: [PATCH v2 0/4] Hybrid event parsing fixes

Correct various issues that have come up in mailing list discussions,
the most impactful of which is the wildcard opening of events of type
PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE. But also try to avoid a
parse-error without a warning, have more fall-back behaviors and be
liberal with the definition of software events.

The majority of the change is in correcting the parse-event test to
match the new hybrid parsing.

Ian Rogers (4):
  perf pmu: Correct perf_pmu__auto_merge_stats affecting hybrid
  perf evsel: Add verbose 3 print of evsel name when opening
  perf parse-events: Wildcard most "numeric" events
  perf test: Update parse-events expectations
