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

Pull x86 microcode loader updates from Ingo Molnar:
 "There are two main changes in this tree:

   - AMD microcode early loading fixes
   - some microcode loader source files reorganization"

* 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, microcode: Move to a proper location
  x86, microcode, AMD: Fix early ucode loading
  x86, microcode: Share native MSR accessing variants
  x86, ramdisk: Export relocated ramdisk VA
