Pull x86 microcode loading updates from Borislav Petkov:
 "The kernel carries a table of Intel CPUs family, model, stepping, etc
  tuples which say what is the latest microcode for that particular CPU.

  Some CPU variants differ only by the platform ID which determines what
  microcode needs to be loaded on them.

  Carve out the platform ID handling from the microcode loader and make it
  available in a more generic place so that the old microcode
  verification machinery can use it"
