From core PMU's perspective, Emerald Rapids is the same as the Sapphire
Rapids. The only difference is the event list, which will be
supported in the perf tool later.

Hi Ingo,

It seems that only the last two patches of the series are merged into
the tip.git perf/urgent branch.

Could you please take the first two patches as well? They similarly add
the CPU model number for perf core driver and perf cstate driver.

Please let me know if you have any questions regarding the first two
patches. If you want me to resend the patches, please let me know as well.

Thanks,
Kan
