Merge branch 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 microcode update from Ingo Molnar:
 "The biggest change (by Borislav Petkov) is a thorough rewrite of the
  Intel microcode loader and its interactions with the core code.

  The biggest conceptual change is the decoupling of the microcode
  loading on boot and application processors (which load the microcode
  in different scenarios), so that both parse the input patches with as
  few assumptions as possible - this also fixes various kernel address
  space randomization bugs. (The AP side then goes on and caches the
  result to improve boot performance.)

  Since the AMD side already did this, this change also opened up the
  path towards more unification/simplification of the core microcode
  loading infrastructure:
