    nab)
    - Convert existing IBLOCK/FILEIO/RAMDISK/PSCSI/TCMU drivers to use
    external configfs attributes. (nab)
    - 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)
    - Fixes for SPC-4 Persistent Reservation AllRegistrants spec

    - Avoid potential short kern_sendmsg() in iscsi-target for now until
    Al's conversion to use msghdr iteration is merged post -rc1.

    Also, Sagi has requested a number of iser-target patches (9) that
    address stability issues he's encountered during extended stress
    testing be considered for v3.10.y + v3.14.y code. Given the amount of

  • 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.
    - Small cleanups and fixes"

  • commit 4dbd27711cd9 "tick: export nohz tick idle symbols for module
    use" was merged via the thermal tree without an explicit ack from the
    relevant maintainers.

    The exports are abused by the intel powerclamp driver which implements
    a fake idle state from a sched FIFO task. This causes all kinds of
    wreckage in the NOHZ core code which rightfully assumes that
    tick_nohz_idle_enter/exit() are only called from the idle task itself.

    Recent changes in the NOHZ core lead to a failure of the powerclamp
    driver and now people try to hack completely broken and backwards
    workarounds into the NOHZ core code. This is completely unacceptable
    and just papers over the real problem. There are way more subtle
    issues lurking around the corner.

    The real solution is to fix the powerclamp driver by rewriting it with
    a sane concept, but that's beyond the scope of this.

    So the only solution for now is to remove the calls into the core NOHZ
    code from the powerclamp trainwreck along with the exports.

    minor intel_pstate driver changes, a new MAINTAINERS entry for it and
    an ACPI fan driver change needed for better support of thermal
    management in user space.

    Specifics:

    - Fix a regression in leds-gpio introduced by a recent commit that
    inadvertently changed the name of one of the properties used by the
    driver (Fabio Estevam).

    - Fix a regression in the ACPI backlight driver introduced by a
    recent fix that missed one special case that had to be taken into
    account (Aaron Lu).

    - Drop the level of some new kernel messages from the ACPI core
    introduced by a recent commit to KERN_DEBUG which they should have
    used from the start and drop some other unuseful KERN_ERR messages
    printed by ACPI (Rafael J Wysocki).

    - Revert an incorrect commit modifying the cpupower tool (Prarit
    Bhargava).

    - Fix two regressions introduced by recent commits in the OPP library
    and clean up some existing minor issues in that code (Viresh
    Kumar).

    - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
    tree (or drop it where that can be done) in order to make it
    possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
    Hansson, Ludovic Desroches).

    There will be one more "CONFIG_PM_RUNTIME removal" batch after this
    one, because some new uses of it have been introduced during the
    current merge window, but that should be sufficient to finally get
    rid of it.

    - Make the ACPI EC driver more robust against race conditions related
    to GPE handler installation failures (Lv Zheng).

    - Prevent the ACPI device PM core code from attempting to disable
    GPEs that it has not enabled which confuses ACPICA and makes it
    report errors unnecessarily (Rafael J Wysocki).

    - Add a "force" command line switch to the intel_pstate driver to
    make it possible to override the blacklisting of some systems in
    that driver if needed (Ethan Zhao).

    - Improve intel_pstate code documentation and add a MAINTAINERS entry
    for it (Kristen Carlson Accardi).

    - Make the ACPI fan driver create cooling device interfaces witn
    names that reflect the IDs of the ACPI device objects they are
    associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").

    That's necessary for user space thermal management tools to be able
    to connect the fans with the parts of the system they are supposed
    to be cooling properly. From Srinivas Pandruvada"

  • Pull second set of media updates from Mauro Carvalho Chehab:

    - Move drivers for really old legacy hardware to staging. Those are
    using obsolete media kAPIs and are for hardware that nobody uses for
    years. Simply not worth porting them to the new kAPIs. Of course,
    if anyone pops up to fix, we can move them back from there

    - While not too late, do some API fixups at the new colorspace API,
    added for v3.19

  • Currently functions in zsmalloc.c does not arranged in a readable and
    reasonable sequence. With the more and more functions added, we may
    meet below inconvenience. For example:

    Current functions:

    void zs_init()
    {
    }

    static void get_maxobj_per_zspage()
    {
    }

    Then I want to add a func_1() which is called from zs_init(), and this
    new added function func_1() will used get_maxobj_per_zspage() which is
    defined below zs_init().

    void func_1()
    {
    get_maxobj_per_zspage()
    }

    void zs_init()
    {
    func_1()
    }

    static void get_maxobj_per_zspage()
    {
    }

    This will cause compiling issue. So we must add a declaration:

    static void get_maxobj_per_zspage();

    before func_1() if we do not put get_maxobj_per_zspage() before
    func_1().

    In addition, puting module_[init|exit] functions at the bottom of the
    file conforms to our habit.

    So, this patch ajusts function sequence as:

    /* helper functions */
    ...
    obj_location_to_handle()
    ...

    /* Some exported functions */
    ...

    zs_map_object()
    zs_unmap_object()

    zs_malloc()
    zs_free()

    zs_init()
    zs_exit()
