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 fix for the kexec/purgatory regression which was introduced in the
   merge window via an innocent sparse fix. We could have reverted that
   commit, but on deeper inspection it turned out that the whole
   machinery is neither documented nor robust. So a proper cleanup was
   done instead

 - the fix for the TLB flush issue which was discovered recently

 - a simple typo fix for a reboot quirk

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86/tlb: Fix tlb flushing when lguest clears PGE
  kexec, x86/purgatory: Unbreak it and clean it up
  x86/reboot/quirks: Fix typo in ASUS EeeBook X205TA reboot quirk
