Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt: "So from the depth of frozen Minnesota, here's the powerpc pull request for 3.9. It has a few interesting highlights, in addition to the usual bunch of bug fixes, minor updates, embedded device tree updates and new boards: - Hand tuned asm implementation of SHA1 (by Paulus & Michael Ellerman) - Support for Doorbell interrupts on Power8 (kind of fast thread-thread IPIs) by Ian Munsie - Long overdue cleanup of the way we handle relocation of our open firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard - Support for saving/restoring & context switching the PPR (Processor Priority Register) on server processors that support it. This allows the kernel to preserve thread priorities established by userspace. By Haren Myneni. - DAWR (new watchpoint facility) support on Power8 by Michael Neuling - Ability to change the DSCR (Data Stream Control Register) which controls cache prefetching on a running process via ptrace by Alexey Kardashevskiy - Support for context switching the TAR register on Power8 (new branch target register meant to be used by some new specific userspace perf event interrupt facility which is yet to be enabled) by Ian Munsie. - Improve preservation of the CFAR register (which captures the origin of a branch) on various exception conditions by Paulus. - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where it belongs by Philippe De Muyter - Support for Transactional Memory on Power8 by Michael Neuling (based on original work by Matt Evans). For those curious about the feature, the patch contains a pretty good description." (See commit db8ff907027b: "powerpc: Documentation for transactional memory on powerpc" for the mentioned description added to the file Documentation/powerpc/transactional_memory.txt) * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (140 commits) powerpc/kexec: Disable hard IRQ before kexec powerpc/85xx: l2sram - Add compatible string for BSC9131 platform powerpc/85xx: bsc9131 - Correct typo in SDHC device node powerpc/e500/qemu-e500: enable coreint powerpc/mpic: allow coreint to be determined by MPIC version powerpc/fsl_pci: Store the pci ctlr device ptr in the pci ctlr struct powerpc/85xx: Board support for ppa8548 powerpc/fsl: remove extraneous DIU platform functions arch/powerpc/platforms/85xx/p1022_ds.c: adjust duplicate test powerpc: Documentation for transactional memory on powerpc powerpc: Add transactional memory to pseries and ppc64 defconfigs powerpc: Add config option for transactional memory powerpc: Add transactional memory to POWER8 cpu features powerpc: Add new transactional memory state to the signal context powerpc: Hook in new transactional memory code powerpc: Routines for FP/VSX/VMX unavailable during a transaction powerpc: Add transactional memory unavaliable execption handler powerpc: Add reclaim and recheckpoint functions for context switching transactional memory processes powerpc: Add FP/VSX and VMX register load functions for transactional memory powerpc: Add helper functions for transactional memory context switching ...
