Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
"Two fixlets for x86:
- Handle WARN_ONs proper with the new UD based WARN implementation
- Disable 1G mappings when 2M mappings are disabled by kmemleak or
debug_pagealloc. Otherwise 1G mappings might still be used,
confusing the debug mechanisms"
* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/mm: Disable 1GB direct mappings when disabling 2MB mappings
x86/debug: Handle early WARN_ONs proper
