    Pull devicetree updates from Rob Herring:
    "DeviceTree updates for 3.13. This is a bit larger pull request than
    usual for this cycle with lots of clean-up.

    - Cross arch clean-up and consolidation of early DT scanning code.
    - Clean-up and removal of arch prom.h headers. Makes arch specific
    prom.h optional on all but Sparc.
    - Addition of interrupts-extended property for devices connected to
    multiple interrupt controllers.
    - Refactoring of DT interrupt parsing code in preparation for
    deferred probe of interrupts.
    - ARM cpu and cpu topology bindings documentation.
    - Various DT vendor binding documentation updates"

  • f27446c3a   microblaze/pci: Drop PowerPC-ism from irq parsing ... Browse Code »

    The Microblaze PCI code copied the PowerPC irq handling, but powerpc
    needs to handle broken device trees that are not present on Microblaze.
    This patch removes the powerpc special case and replaces it with a
    direct of_irq_parse_and_map_pci() call.

  • e6d30ab1e   of/irq: simplify args to irq_create_of_mapping ... Browse Code »

    All the callers of irq_create_of_mapping() pass the contents of a struct
    of_phandle_args structure to the function. Since all the callers already
    have an of_phandle_args pointer, why not pass it directly to
    irq_create_of_mapping()?

  • 530210c78   of/irq: Replace of_irq with of_phandle_args ... Browse Code »

    struct of_irq and struct of_phandle_args are exactly the same structure.
    This patch makes the kernel use of_phandle_args everywhere. This in
    itself isn't a big deal, but it makes some follow-on patches simpler.

  • 0c02c8007   of/irq: Rename of_irq_map_* functions to of_irq_parse_* ... Browse Code »

    The OF irq handling code has been overloading the term 'map' to refer to
    both parsing the data in the device tree and mapping it to the internal
    linux irq system. This is probably because the device tree does have the
    concept of an 'interrupt-map' function for translating interrupt
    references from one node to another, but 'map' is still confusing when
    the primary purpose of some of the functions are to parse the DT data.

    This patch renames all the of_irq_map_* functions to of_irq_parse_*
    which makes it clear that there is a difference between the parsing
    phase and the mapping phase. Kernel code can make use of just the
    parsing or just the mapping support as needed by the subsystem.

    The patch was generated mechanically with a handful of sed commands.

  • 32df8dca5   of: remove HAVE_ARCH_DEVTREE_FIXUPS ... Browse Code »

    HAVE_ARCH_DEVTREE_FIXUPS appears to always be needed except for sparc,
    but it is only used for /proc/device-teee and sparc does not enable
    /proc/device-tree. So this option is redundant. Remove the option and
    always enable it. This has the side effect of fixing /proc/device-tree
    on arches such as arm64 which failed to define this option.

  • 759496ba6   arch: mm: pass userspace fault flag to generic fault handler ... Browse Code »

    Unlike global OOM handling, memory cgroup code will invoke the OOM killer
    in any OOM situation because it has no way of telling faults occuring in
    kernel context - which could be handled more gracefully - from
    user-triggered faults.

    Pass a flag that identifies faults originating in user space from the
    architecture-specific fault handlers to generic code so that memcg OOM
    handling can be improved.

    the entire flattened tree into the random pool at boot. May not be

    be noticeable. And "add_device_randomness()" is definitely not some
