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

Pull x86 microcode loading updates from Ingo Molnar:
 "The main changes in this cycle are:

   - Reload microcode when resuming and the case when only the early
     loader has been utilized.  (Borislav Petkov)

   - Also, do not load the driver on paravirt guests.  (Boris
     Ostrovsky)"

* 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/microcode/intel: Fish out the stashed microcode for the BSP
  x86, microcode: Reload microcode on resume
  x86, microcode: Don't initialize microcode code on paravirt
  x86, microcode, intel: Drop unused parameter
  x86, microcode, AMD: Do not use smp_processor_id() in preemtible context
