[GIT PULL] Please pull powerpc/linux.git powerpc-4.12-2 tag

[Michael Ellerman]

Hi Linus,

Please pull the second batch of powerpc updates for 4.12.

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.

The following changes since commit 700b7eadd5625d22b8235fb21259b3d7d564c000:

  powerpc/64s: Power9 has no LPCR[VRMASD] field so don't set it (2017-05-03 20:45:55 +1000)

  powerpc/64s: Support new device tree binding for discovering CPU features (2017-05-09 23:42:55 +1000)

----------------------------------------------------------------
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.
