Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 mm updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Update and clean up x86 fault handling, by Andy Lutomirski.

   - Drop usage of __flush_tlb_all() in kernel_physical_mapping_init()
     and related fallout, by Dan Williams.

   - CPA cleanups and reorganization by Peter Zijlstra: simplify the
     flow and remove a few warts.

   - Other misc cleanups"
