Merge tag 'x86_cpu_for_v5.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu feature updates from Borislav Petkov:
- Merge the AMD and Intel PPIN code into a shared one by both vendors.
Add the PPIN number to sysfs so that sockets can be identified when
replacement is needed
- Minor fixes and cleanups
