Subject: [PATCH v2 0/5] perf hwmon related improvements

Try to do less scanning of files/directories with or without hwmon
PMUs. Don't merge all events with the same name, only merge those on
the same PMU ignoring suffix. Tidy PMU name matching to distinguish no
suffix or wildcard matching. Refactor uniquification so the evsels
with the same name as other evsels in the evlist are uniquified.

v2: Rename ignore suffix PMU name matching that is really a
    wildcard/prefix match. Use a proper ignore suffix when not merging
    counters purely on name.

Ian Rogers (5):
  perf evsel: Reduce scanning core PMUs in is_hybrid
  perf pmus: Restructure pmu_read_sysfs to scan fewer PMUs
  perf pmu: Rename name matching for no suffix or wildcard variants
  perf stat: Don't merge counters purely on name
  perf stat: Changes to event name uniquification
