  • Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger:
    "kernel: Provide READ_ONCE and ASSIGN_ONCE

    As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
    ACCESS_ONCE might fail with specific compilers for non-scalar
    accesses.

    Here is a set of patches to tackle that problem.

    The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data
    structure is larger than the machine word size memcpy is used and a
    warning is emitted. The next patches fix up several in-tree users of
    ACCESS_ONCE on non-scalar types.

    This does not yet contain a patch that forces ACCESS_ONCE to work only
    on scalar types. This is targetted for the next merge window as Linux
    next already contains new offenders regarding ACCESS_ONCE vs.
    non-scalar types"

    - Allow target fabric drivers to function as built-in. (Roland)
    - Fix tcm_loop multi-TPG endpoint nexus bug. (Hannes)
    - Move per device config_item_type into se_subsystem_api, allowing

    - Convert existing IBLOCK/FILEIO/RAMDISK/PSCSI/TCMU drivers to use

    - A number of iser-target fixes related to active session + network
    portal shutdown stability during extended stress testing. (Sagi +
    Slava)
    - Dynamic allocation of T10-PI contexts for iser-target, fixing a
    potentially bogus iscsi_np->tpg_np pointer reference in >= v3.14
    code. (Sagi)
    - iser-target performance + scalability improvements. (Sagi)

  • strcmp was lost when all other string functions were removed,
    but we still have an optimized version for this on CRISv32,
    so any driver built as a module would not have access to this symbol.

    In a similar manner, we had optimized versions of
    csum_partial_copy_from_user and __do_clear_user
    but no exported symbols for them, breaking bunch of other drivers
    when built as a module.

    At the same time, move EXPORT_SYMBOL(__copy_user) and
    EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
    located together with the function definition.

  • Pull x86 apic updates from Thomas Gleixner:
    "After stopping the full x86/apic branch, I took some time to go
    through the first block of patches again, which are mostly cleanups
    and preparatory work for the irqdomain conversion and ioapic hotplug
    support.

    Unfortunaly one of the real problematic commits was right at the
    beginning, so I rebased this portion of the pending patches without
    the offenders.

    It would be great to get this into 3.19. That makes reworking the
    problematic parts simpler. The usual tip testing did not unearth any
    issues and it is fully bisectible now.

    I'm pretty confident that this wont affect the calmness of the xmas
    season.

    Changes:
    - Split the convoluted io_apic.c code into domain specific parts
    (vector, ioapic, msi, htirq)
    - Introduce proper helper functions to retrieve irq specific data
    instead of open coded dereferencing of pointers
    - Preparatory work for ioapic hotplug and irqdomain conversion
    - Removal of the non functional pci-ioapic driver
    - Removal of unused irq entry stubs
    - Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
    allocations for everything which is called from there.

  • Pull second batch of powerpc updates from Michael Ellerman:
    "The highlight is the series that reworks the idle management on
    powernv, which allows us to use deeper idle states on those machines.

    There's the fix from Anton for the "BUG at kernel/smpboot.c:134!"
    problem.

    An i2c driver for powernv. This is acked by Wolfram Sang, and he
    asked that we take it through the powerpc tree.

    A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of
    the audit maintainers.

    A patch from Ben to export the symbol map of our OPAL firmware as a
    sysfs file, so that tools can use it.

    Also some CXL fixes, a couple of powerpc perf fixes, a fix for
    smt-enabled, and the patch to add __force to get_user() so we can use
    bitwise types"

    * tag 'powerpc-3.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux:
    powerpc/powernv: Ignore smt-enabled on Power8 and later
    powerpc/uaccess: Allow get_user() with bitwise types

    power/perf/hv-24x7: Use kmem_cache_free() instead of kfree
    powerpc/perf/hv-24x7: Use per-cpu page buffer
    cxl: Unmap MMIO regions when detaching a context
    cxl: Add timeout to process element commands

  • I'm leaving Red Hat at the end of December 2014, so remove all
    references to my soon-to-be-dead address.

    (There are some references left in the tree, that need additional
    changes, I'll send those through the AGP maintainers).
