Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc update from Benjamin Herrenschmidt: "The main highlight is probably some base POWER8 support. There's more to come such as transactional memory support but that will wait for the next one. Overall it's pretty quiet, or rather I've been pretty poor at picking things up from patchwork and reviewing them this time around and Kumar no better on the FSL side it seems..." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (73 commits) powerpc+of: Rename and fix OF reconfig notifier error inject module powerpc: mpc5200: Add a3m071 board support powerpc/512x: don't compile any platform DIU code if the DIU is not enabled powerpc/mpc52xx: use module_platform_driver macro powerpc+of: Export of_reconfig_notifier_[register,unregister] powerpc/dma/raidengine: add raidengine device powerpc/iommu/fsl: Add PAMU bypass enable register to ccsr_guts struct powerpc/mpc85xx: Change spin table to cached memory powerpc/fsl-pci: Add PCI controller ATMU PM support powerpc/86xx: fsl_pcibios_fixup_bus requires CONFIG_PCI drivers/virt: the Freescale hypervisor driver doesn't need to check MSR[GS] powerpc/85xx: p1022ds: Use NULL instead of 0 for pointers powerpc: Disable relocation on exceptions when kexecing powerpc: Enable relocation on during exceptions at boot powerpc: Move get_longbusy_msecs into hvcall.h and remove duplicate function powerpc: Add wrappers to enable/disable relocation on exceptions powerpc: Add set_mode hcall powerpc: Setup relocation on exceptions for bare metal systems powerpc: Move initial mfspr LPCR out of __init_LPCR powerpc: Add relocation on exception vector handlers ...
