    Pull powerpc updates from Ben Herrenschmidt:
    "So here's my next branch for powerpc. A bit late as I was on vacation
    last week. It's mostly the same stuff that was in next already, I
    just added two patches today which are the wiring up of lockref for
    powerpc, which for some reason fell through the cracks last time and
    is trivial.

    The highlights are, in addition to a bunch of bug fixes:

    - Reworked Machine Check handling on kernels running without a
    hypervisor (or acting as a hypervisor). Provides hooks to handle
    some errors in real mode such as TLB errors, handle SLB errors,
    etc...

    - Support for retrieving memory error information from the service
    processor on IBM servers running without a hypervisor and routing
    them to the memory poison infrastructure.

    - _PAGE_NUMA support on server processors

    - 32-bit BookE relocatable kernel support

    - FSL e6500 hardware tablewalk support

    - A bunch of new/revived board support

    - FSL e6500 deeper idle states and altivec powerdown support

    You'll notice a generic mm change here, it has been acked by the
    relevant authorities and is a pre-req for our _PAGE_NUMA support"

  • 50bd6153d   powerpc/powernv: Code update interface ... Browse Code »

    Code update interface for powernv platform. This provides
    sysfs interface to pass new image, validate, update and
    commit images.

    This patch includes:
    - Below OPAL APIs for code update
    - opal_validate_flash()
    - opal_manage_flash()
    - opal_update_flash()

    - Create below sysfs files under /sys/firmware/opal
    - image : Interface to pass new FW image
    - validate_flash : Validate candidate image
    - manage_flash : Commit/Reject operations
    - update_flash : Flash new candidate image

    Updating Image:
    "update_flash" is an interface to indicate flash new FW.
    It just passes image SG list to FW. Actual flashing is done
    during system reboot time.

    Note:
    - SG entry format:
    I have kept version number to keep this list similar to what
    PAPR is defined.
