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
