Merge tag 'powerpc-4.11-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc...

Pull some more powerpc fixes from Michael Ellerman:
 "The main item is the addition of the Power9 Machine Check handler.
  This was delayed to make sure some details were correct, and is as
  minimal as possible.

  The rest is small fixes, two for the Power9 PMU, two dealing with
  obscure toolchain problems, two for the PowerNV IOMMU code (used by
  VFIO), and one to fix a crash on 32-bit machines with macio devices
  due to missing dma_ops.

  Thanks to:
    Alexey Kardashevskiy, Cyril Bur, Larry Finger, Madhavan Srinivasan,
    Nicholas Piggin"
