Merge tag 'powerpc-4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: - support "hybrid" iommu/direct DMA ops for coherent_mask < dma_mask from Benjamin Herrenschmidt - EEH fixes for SRIOV from Gavin - introduce rtas_get_sensor_fast() for IRQ handlers from Thomas Huth - use hardware RNG for arch_get_random_seed_* not arch_get_random_* from Paul Mackerras - seccomp filter support from Michael Ellerman - opal_cec_reboot2() handling for HMIs & machine checks from Mahesh Salgaonkar - add powerpc timebase as a trace clock source from Naveen N. Rao - misc cleanups in the xmon, signal & SLB code from Anshuman Khandual - add an inline function to update POWER8 HID0 from Gautham R. Shenoy - fix pte_pagesize_index() crash on 4K w/64K hash from Michael Ellerman - drop support for 64K local store on 4K kernels from Michael Ellerman - move dma_get_required_mask() from pnv_phb to pci_controller_ops from Andrew Donnellan - initialize distance lookup table from drconf path from Nikunj A Dadhania - enable RTC class support from Vaibhav Jain - disable automatically blocked PCI config from Gavin Shan - add LEDs driver for PowerNV platform from Vasant Hegde - fix endianness issues in the HVSI driver from Laurent Dufour - kexec endian fixes from Samuel Mendoza-Jonas - fix corrupted pdn list from Gavin Shan - fix fenced PHB caused by eeh_slot_error_detail() from Gavin Shan - Freescale updates from Scott: Highlights include 32-bit memcpy/memset optimizations, checksum optimizations, 85xx config fragments and updates, device tree updates, e6500 fixes for non-SMP, and misc cleanup and minor fixes. - a ton of cxl updates & fixes: - add explicit precision specifiers from Rasmus Villemoes - use more common format specifier from Rasmus Villemoes - destroy cxl_adapter_idr on module_exit from Johannes Thumshirn - destroy afu->contexts_idr on release of an afu from Johannes Thumshirn - compile with -Werror from Daniel Axtens - EEH support from Daniel Axtens - plug irq_bitmap getting leaked in cxl_context from Vaibhav Jain - add alternate MMIO error handling from Ian Munsie - allow release of contexts which have been OPENED but not STARTED from Andrew Donnellan - remove use of macro DEFINE_PCI_DEVICE_TABLE from Vaishali Thakkar - release irqs if memory allocation fails from Vaibhav Jain - remove racy attempt to force EEH invocation in reset from Daniel Axtens - fix + cleanup error paths in cxl_dev_context_init from Ian Munsie - fix force unmapping mmaps of contexts allocated through the kernel api from Ian Munsie - set up and enable PSL Timebase from Philippe Bergheaud * tag 'powerpc-4.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: (140 commits) cxl: Set up and enable PSL Timebase cxl: Fix force unmapping mmaps of contexts allocated through the kernel api cxl: Fix + cleanup error paths in cxl_dev_context_init powerpc/eeh: Fix fenced PHB caused by eeh_slot_error_detail() powerpc/pseries: Cleanup on pci_dn_reconfig_notifier() powerpc/pseries: Fix corrupted pdn list powerpc/powernv: Enable LEDS support powerpc/iommu: Set default DMA offset in dma_dev_setup cxl: Remove racy attempt to force EEH invocation in reset cxl: Release irqs if memory allocation fails cxl: Remove use of macro DEFINE_PCI_DEVICE_TABLE powerpc/powernv: Fix mis-merge of OPAL support for LEDS driver powerpc/powernv: Reset HILE before kexec_sequence() powerpc/kexec: Reset secondary cpu endianness before kexec powerpc/hvsi: Fix endianness issues in the HVSI driver leds/powernv: Add driver for PowerNV platform powerpc/powernv: Create LED platform device powerpc/powernv: Add OPAL interfaces for accessing and modifying system LED states powerpc/powernv: Fix the log message when disabling VF cxl: Allow release of contexts which have been OPENED but not STARTED ...
