Right now, cpu_request_microcode() ends up consuming the currently-loaded
microcode revision (and discarding the answer), simply because the helpers are
too overloaded.

Andrew Cooper (3):
  x86/ucode: Rework Intel's microcode_update_match()
  x86/ucode: Rework AMD's microcode_fits()
  x86/ucode: Drop MIS_UCODE and microcode_match_result
