Merge tag 'x86_cpu_for_v5.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cpu updates from Borislav Petkov:

 - New AMD models support

 - Allow MONITOR/MWAIT to be used for C1 state entry on Hygon too

 - Use the special RAPL CPUID bit to detect the functionality on AMD and
   Hygon instead of doing family matching.

 - Add support for new Intel microcode deprecating TSX on some models
   and do not enable kernel workarounds for those CPUs when TSX
   transactions always abort, as a result of that microcode update.
