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

Pull x86 boot updates from Ingo Molnar:
 "The biggest changes in this cycle were:

   - reworking of the e820 code: separate in-kernel and boot-ABI data
     structures and apply a whole range of cleanups to the kernel side.

     No change in functionality.

   - enable KASLR by default: it's used by all major distros and it's
     out of the experimental stage as well.

   - ... misc fixes and cleanups"
