With the mem_events, perf doesn't need to read sysfs for each PMU to find the mem-events-supported PMU. The patch also makes it possible to clean up the related __weak functions later. The patch is only to add the mem_events into the perf_pmu for all ARCHs. It will be used in the later cleanup patches.
