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
