Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a handful of powerpc fixes for 3.13.

  The patches are reasonably trivial and self contained.  Note the offb
  patches outside of arch/powerpc, they are LE fixes for our
  open-firmware 'dumb' framebuffer"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc: Fix up the kdump base cap to 128M
  powernv: Fix VFIO support with PHB3
  powerpc/52xx: Re-enable bestcomm driver in defconfigs
  powerpc/pasemi: Turn on devtmpfs in defconfig
  offb: Add palette hack for little endian
  offb: Little endian fixes
  powerpc: Fix PTE page address mismatch in pgtable ctor/dtor
  powerpc/44x: Fix ocm_block allocation
  powerpc: Fix build break with PPC_EARLY_DEBUG_BOOTX=y
  powerpc/512x: dts: remove misplaced IRQ spec from 'soc' node
