Linus Torvalds 156fa7417f x86 fixes:
- Reject the loading of a potentially problematic microcode version
    on Intel Granite Rapids systems (Chang S. Bae)
 
  - On FRED, reconstruct the proper #GP context for rejected INT
    instructions, to fix a signal ABI regression (Matthew Schwartz)
 
  - Add a test for this signal ABI regression the x86
    self-test suite (Matthew Schwartz)
 
  - Don't emit the new and not yet properly supported EGPR instructions
    (%r16-%r31) on CONFIG_X86_NATIVE_CPU=y builds (Chang S. Bae)
