Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"A set of small fixes for 4.15:
- Fix vmapped stack synchronization on systems with 4-level paging
and a large amount of memory caused by a missing 5-level folding
which made the pgd synchronization logic to fail and causing double
faults.
- Add a missing sanity check in the vmalloc_fault() logic on 5-level
paging systems.
- Bring back protection against accessing a freed initrd in the
microcode loader which was lost by a wrong merge conflict
resolution.
- Extend the Broadwell micro code loading sanity check.
- Add a missing ENDPROC annotation in ftrace assembly code which
makes ORC unhappy.
- Prevent loading the AMD power module on !AMD platforms. The load
itself is uncritical, but an unload attempt results in a kernel
crash.
- Update Peter Anvins role in the MAINTAINERS file"
