Merge tag 'x86_microcode_for_v7.2_rc1' of gitolite.kernel.org:pub/scm/linux/kernel...

Pull x86 microcode loader updates from Borislav Petkov:

 - Move the zero-revision fixup for AMD microcode to the patch level
   retrieval function and restrict it to Zen family processors, ensuring
   patch level arithmetic always operates on a valid revision

 - Fix an incorrect comment about which CPUID bit is checked when
   determining whether the microcode loader should be disabled

 - Add the latest Intel microcode revision data for a broad range of
   processor models and steppings and add the script which generates the
   header of minimum expected Intel microcode revisions
