Subject[GIT PULL] x86/boot changes for v4.8
Linus,

Please pull the latest x86-boot-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-boot-for-linus

# HEAD: 6a79296cb15d947bcb4558011fe066e5d8252b35 x86/boot: Simplify EBDA-vs-BIOS reservation logic

Note: please only pull this tree if you've already pulled x86-mm-for-linus.

The main changes:

- Add initial commits to randomize kernel memory section virtual addresses,
enabled via a new kernel option: CONFIG_RANDOMIZE_MEMORY=y.
(Thomas Garnier, Kees Cook, Baoquan He, Yinghai Lu)

- Enhance KASLR (CONFIG_RANDOMIZE_BASE) physical memory randomization.
(Kees Cook)

- EBDA/BIOS region boot quirk cleanups (Andy Lutomirski, Ingo Molnar)

- misc cleanups/fixes.

Thanks,

Ingo
