Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Ben Herrenschmidt:
"Here's the powerpc batch for this merge window. Some of the
highlights are:
- A bunch of endian fixes ! We don't have full LE support yet in that
release but this contains a lot of fixes all over arch/powerpc to
use the proper accessors, call the firmware with the right endian
mode, etc...
- A few updates to our "powernv" platform (non-virtualized, the one
to run KVM on), among other, support for bridging the P8 LPC bus
for UARTs, support and some EEH fixes.
- Some mpc51xx clock API cleanups in preparation for a clock API
overhaul
- A pile of cleanups of our old math emulation code, including better
support for using it to emulate optional FP instructions on
embedded chips that otherwise have a HW FPU.
- Some infrastructure in selftest, for powerpc now, but could be
generalized, initially used by some tests for our perf instruction
counting code.
- A pile of fixes for hotplug on pseries (that was seriously
bitrotting)
- The usual slew of freescale embedded updates, new boards, 64-bit
hiberation support, e6500 core PMU support, etc..."
