Ian Rogers 8e7d8a2eef perf pmus: Avoid repeated sysfs scanning
perf_pmus__scan will process every directory in sysfs to see if it is
a PMU, attempting to add it if not already in the pmus list. Add two
booleans to record whether this scanning has been done for core or all
PMUs. Skip scanning in the event that scanning has already occurred.
