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:
"Most of the changes center around the difficult problem of KASLR
pinning down hot-removable memory regions. At the very early stage
KASRL is making irreversible kernel address layout decisions we don't
have full knowledge about the memory maps yet.
So the changes from Chao Fan add this (parsing the RSDP table early),
together with fixes from Borislav Petkov"
