The perf_mem_events__name() can generate the mem-load event name. It uses a variable 'mem_loads_name__init' to avoid generating the event name every time (because perf_pmu__scan takes some time). The perf_mem_events__name() assumes the pmu is "cpu" but it's not correct for hybrid platform. For Alderlake, the pmu is "cpu_core" or "cpu_atom" Introduce a new parameter 'pmu_name' in perf_mem_events__name to let the caller specify a pmu name. Considering such event name is x86 specific, so move perf_mem_events[] to arch/x86/util/mem-events.c. We still keep the variable 'mem_loads_name__init' but it's only used when pmu_name is NULL (compatible for original behavior). When pmu_name is not NULL (e.g. "cpu_core"), this patch doesn't have optimization. That can be implemented in follow up patch.
