Subject: [PATCH 6/6] perf, test: Add automated tests for pmu sysfs translated events
Adding automated tests for all events found under PMU/events
directory. Tested events are in 'cpu/event=xxx/u' format,
where 'xxx' is substibuted by every event found.
The 'event=xxx' term is translated to the cpu specific term.
We only check that the event is created (not the real config
numbers) and that modifier is properly set.
