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:

   - A PAT series from Davidlohr Bueso, which simplifies the memtype
     rbtree by using the interval tree helpers. (There's more cleanups
     in this area queued up, but they didn't make the merge window.)

   - Also flip over CONFIG_X86_5LEVEL to default-y. This might draw in a
     few more testers, as all the major distros are going to have
     5-level paging enabled by default in their next iterations.

   - Misc cleanups"
