Linus Torvalds dc2a248166 powerpc updates for 4.12 part 2 
Highlights include:
 
  - rework the Linux page table geometry to lower memory usage on 64-bit Book3S
    (IBM chips) using the Hash MMU.
 
  - support for a new device tree binding for discovering CPU features on future
    firmwares.
 
  - Freescale updates from Scott: "Includes a fix for a powerpc/next mm regression
    on 64e, a fix for a kernel hang on 64e when using a debugger inside a
    relocated kernel, a qman fix, and misc qe improvements."
 
 Thanks to:
   Christophe Leroy, Gavin Shan, Horia Geantă, LiuHailong, Nicholas Piggin, Roy
   Pledge, Scott Wood, Valentin Longchamp.

Merge tag 'powerpc-4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull more powerpc updates from Michael Ellerman:
 "The change to the Linux page table geometry was delayed for more
  testing with 16G pages, and there's the new CPU features stuff which
  just needed one more polish before going in. Plus a few changes from
  Scott which came in a bit late. And then various fixes, mostly minor.

  Summary highlights:

   - rework the Linux page table geometry to lower memory usage on
     64-bit Book3S (IBM chips) using the Hash MMU.

   - support for a new device tree binding for discovering CPU features
     on future firmwares.

   - Freescale updates from Scott:
      "Includes a fix for a powerpc/next mm regression on 64e, a fix for
       a kernel hang on 64e when using a debugger inside a relocated
       kernel, a qman fix, and misc qe improvements."
