Linus Torvalds 2f23a7c914 Misc fixes: 
- 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
