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"
