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: 6c3b56b1973083e2bb4e87eb90ea5368455706dc x86/boot: Disable Clang warnings about GNU extensions

Three smaller changes:

- clang fix
- boot message beautification
- unnecessary header inclusion removal

Thanks,

Ingo
