For some ARCHs, e.g., ARM and AMD, to get the availability of the mem-events, perf checks the existence of a specific PMU. For the other ARCHs, e.g., Intel and Power, perf has to check the existence of some specific events. The current perf only iterates the mem-events-supported PMUs. It's not required to check the existence of a specific PMU anymore. Rename sysfs_name to event_name, which stores the specific mem-events. Perf only needs to check those events for the availability of the mem-events. Rename perf_mem_event__supported to perf_pmu__mem_events_supported.
