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..." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (146 commits) powerpc: Correct FSCR bit definitions powerpc/xmon: Fix printing of set of CPUs in xmon powerpc/pseries: Move lparcfg.c to platforms/pseries powerpc/powernv: Return secondary CPUs to firmware on kexec powerpc/btext: Fix CONFIG_PPC_EARLY_DEBUG_BOOTX on ppc32 powerpc: Cleanup handling of the DSCR bit in the FSCR register powerpc/pseries: Child nodes are not detached by dlpar_detach_node powerpc/pseries: Add mising of_node_put in delete_dt_node powerpc/pseries: Make dlpar_configure_connector parent node aware powerpc/pseries: Do all node initialization in dlpar_parse_cc_node powerpc/pseries: Fix parsing of initial node path in update_dt_node powerpc/pseries: Pack update_props_workarea to map correctly to rtas buffer header powerpc/pseries: Fix over writing of rtas return code in update_dt_node powerpc/pseries: Fix creation of loop in device node property list powerpc: Skip emulating & leave interrupts off for kernel program checks powerpc: Add more exception trampolines for hypervisor exceptions powerpc: Fix location and rename exception trampolines powerpc: Add more trap names to xmon powerpc/pseries: Add a warning in the case of cross-cpu VPA registration powerpc: Update the 00-Index in Documentation/powerpc ...
