Merge branch 'x86-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull x86 fixes from Thomas Gleixner:
 "A small set of changes:

   - a fixup for kexec related to 5-level paging mode. That covers most
     of the cases except kexec from a 5-level kernel to a 4-level
     kernel. The latter needs more work and is going to come in 4.17

   - two trivial fixes for build warnings triggered by LTO and gcc-8"
