Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt: "The bulk of this is LE updates. One should now be able to build an LE kernel and even run some things in it. I'm still sitting on a handful of patches to enable the new ABI that I *might* still send this merge window around, but due to the incertainty (they are pretty fresh) I want to keep them separate. Other notable changes are some infrastructure bits to better handle PCI pass-through under KVM, some bits and pieces added to the new PowerNV platform support such as access to the CPU SCOM bus via sysfs, and support for EEH error handling on PHB3 (Power8 PCIe). We also grew arch_get_random_long() for both pseries and powernv when running on P7+ and P8, exploiting the HW rng. And finally various embedded updates from freescale" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (154 commits) powerpc: Fix fatal SLB miss when restoring PPR powerpc/powernv: Reserve the correct PE number powerpc/powernv: Add PE to its own PELTV powerpc/powernv: Add support for indirect XSCOM via debugfs powerpc/scom: Improve debugfs interface powerpc/scom: Enable 64-bit addresses powerpc/boot: Properly handle the base "of" boot wrapper powerpc/bpf: Support MOD operation powerpc/bpf: Fix DIVWU instruction opcode of: Move definition of of_find_next_cache_node into common code. powerpc: Remove big endianness assumption in of_find_next_cache_node powerpc/tm: Remove interrupt disable in __switch_to() powerpc: word-at-a-time optimization for 64-bit Little Endian powerpc/bpf: BPF JIT compiler for 64-bit Little Endian powerpc: Only save/restore SDR1 if in hypervisor mode powerpc/pmu: Fix ADB_PMU_LED_IDE dependencies powerpc/nvram: Fix endian issue when using the partition length powerpc/nvram: Fix endian issue when reading the NVRAM size powerpc/nvram: Scan partitions only once powerpc/mpc512x: remove unnecessary #if ...
