Merge tag 'x86-urgent-2022-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc x86 fixes from Ingo Molnar:
- Fix PAT on Xen, which caused i915 driver failures
- Fix compat INT 80 entry crash on Xen PV guests
- Fix 'MMIO Stale Data' mitigation status reporting on older Intel CPUs
- Fix RSB stuffing regressions
- Fix ORC unwinding on ftrace trampolines
- Add Intel Raptor Lake CPU model number
- Fix (work around) a SEV-SNP bootloader bug providing bogus values in
boot_params->cc_blob_address, by ignoring the value on !SEV-SNP
bootups.
- Fix SEV-SNP early boot failure
- Fix the objtool list of noreturn functions and annotate snp_abort(),
which bug confused objtool on gcc-12.
- Fix the documentation for retbleed
