Linus Torvalds 17b6c49da3 - Add a new Intel model number for Alder Lake

- Differentiate which aspects of the FPU state get saved/restored when the FPU
    is used in-kernel and fix a boot crash on K7 due to early MXCSR access before
    CR4.OSFXSR is even set.
 
  - A couple of noinstr annotation fixes
 
  - Correct die ID setting on AMD for users of topology information which need
    the correct die ID
 
  - A SEV-ES fix to handle string port IO to/from kernel memory properly
