[PATCH v3 0/5] Event parsing fixes

[Ian Rogers]

For the default events, parse from strings rather than use pre-cooked
perf_event_attr. This fixes non-x86 heterogeneous CPUs where legacy
hardware events wouldn't be opened for all PMUs. v2 was previously
just patch 3 but it is extended in v3 to incorporate related fixes.

When a sysfs/json event is used in preference to a legacy event, allow
evsel__match to still function using a saved hardware config
number. This fixes hard coded metrics in stat-shadow for events like
"instructions" on Intel that have a sysfs file.

Fix/improve uniquifying event names fixing the test "102: perf stat
metrics (shadow stat) test:" that was broken by a formatting issue
when the sysfs instructions event was used.

Having evsel->pmu_name and evsel->pmu->name is confusing, get rid of
the former. Fix/improve evsel__sys_has_perf_metrics in the process.

Ian Rogers (5):
  perf evsel: Add alternate_hw_config and use in evsel__match
  perf stat: Uniquify event name improvements
  perf stat: Remove evlist__add_default_attrs use strings
  perf evsel x86: Make evsel__has_perf_metrics work for legacy events
  perf evsel: Remove pmu_name
