The patchset is on top of PeterZ's perf/core branch plus
commit id 6e1239c13953 ("x86/cpu: Add another Alder Lake CPU to the 
Intel family")

The above patch is also missed in the tip/perf/core branch. All the 
issues should be gone once the tip/perf/core sync with the tip/x86/urgent.


Thanks,
Kan
