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

Pull x86 boot updates from Ingo Molnar:
 "The main changes are KASL related fixes and cleanups: in particular we
  now exclude certain physical memory ranges as KASLR randomization
  targets that have proven to be unreliable (early-)RAM on some firmware
  versions"
