Merge tag 'x86-cpu-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Ingo Molnar:
- Rework the x86 CPU vendor/family/model code: introduce the 'VFM'
value that is an 8+8+8 bit concatenation of the vendor/family/model
value, and add macros that work on VFM values. This simplifies the
addition of new Intel models & families, and simplifies existing
enumeration & quirk code.
- Add support for the AMD 0x80000026 leaf, to better parse topology
information
- Optimize the NUMA allocation layout of more per-CPU data structures
- Improve the workaround for AMD erratum 1386
- Clear TME from /proc/cpuinfo as well, when disabled by the firmware
- Improve x86 self-tests
- Extend the mce_record tracepoint with the ::ppin and ::microcode fields
- Implement recovery for MCE errors in TDX/SEAM non-root mode
- Misc cleanups and fixes
