Sure, The commit I'm referring to here is
"[PATCH V2 2/2] perf/x86/rapl: Clean up cpumask and hotplug"
(https://lore.kernel.org/all/20241010142604.770192-2-kan.liang@xxxxxxxxxxxxxxx/)
It is not yet merged, but I've taken it as base for this patch series.

It removes the cpumask handling from rapl.c. Hence, we no longer need the
get_rapl_pmu_cpumask() function.

I can post a new version or provide newly drafted commit msg here, whichever way is
okay with the maintainers.

Thanks,
Dhananjay
