  x86/tsx: Clear CPUID bits when TSX always force aborts (2021-06-15 17:46:48 +0200)

----------------------------------------------------------------
- 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.
