      Pull configfs updates from Christoph Hellwig:
       "I'm assisting Joel as co-maintainer and patch monkey now, and you will
        see pull reuquests from me for a while.
        Besides the MAINTAINERS update there is just a single change, which
        adds support for binary attributes to configfs, which are very similar
        to the sysfs binary attributes.  Thanks to Pantelis Antoniou!
        You will see another actually bigger set of configfs changes in the
        SCSI target pull from Nic - those were merged before this new tree
        even existed"

      Pull GFS2 updates from Bob Peterson:
       "Here is a list of patches we've accumulated for GFS2 for the current
        upstream merge window.  Last window's set was short, but I warned that
        this one would be bigger, and so it is.  We've got 19 patches:
         - A patch from Abhi Das to propagate the GFS2_DIF_SYSTEM bit so that
           newly added journals don't get flagged, deleted, and recreated by
         - Two patches from Andreas Gruenbacher to improve GFS2 performance
           where extended attributes are involved.
         - A patch from Andy Price to fix a suspicious rcu dereference error.
         - Two patches from Ben Marzinski that rework how GFS2's NFS cookies
           are managed.  This fixes readdir problems with nfs-over-gfs2.
         - A patch from Ben Marzinski that fixes a race in unmounting GFS2.
         - A set of four patches from me to move the resource group
           reservations inside the gfs2 inode to improve performance and fix a
           bug whereby get_write_access improperly prevented some operations
           like chown.
         - A patch from me to spinlock-protect the setting of system statfs
           file data.  This was causing small discrepancies between df and du.
         - A patch from me to reintroduce a timeout while clearing glocks
           which was accidentally dropped some time ago.
         - A patch from me to wait for iopen glock dequeues in order to
           improve deleting of files that were unlinked from a different
           cluster node.
         - A patch from me to ensure metadata address spaces get truncated
           when an inode is evicted.
         - A patch from me to fix a bug in which a memory leak could occur in
           some error cases when inodes were trying to be created.
         - A patch to consistently use iopen glocks to transition from the
           unlinked state to the deleted state.
         - A patch to fix a glock reference count error when inode creation
         - A patch from Junxiao Bi to fix an flock panic.
         - A patch from Markus Elfring that removes an unnecessary if"

      Pull misc vfs updates from Al Viro:
       "All kinds of stuff.  That probably should've been 5 or 6 separate
        branches, but by the time I'd realized how large and mixed that bag
        had become it had been too close to -final to play with rebasing.
        Some fs/namei.c cleanups there, memdup_user_nul() introduction and
        switching open-coded instances, burying long-dead code, whack-a-mole
        of various kinds, several new helpers for ->llseek(), assorted
        cleanups and fixes from various people, etc.
        One piece probably deserves special mention - Neil's
        lookup_one_len_unlocked().  Similar to lookup_one_len(), but gets
        called without ->i_mutex and tries to avoid ever taking it.  That, of
        course, means that it's not useful for any directory modifications,
        but things like getting inode attributes in nfds readdirplus are fine
        with that.  I really should've asked for moratorium on lookup-related
        changes this cycle, but since I hadn't done that early enough...  I
        *am* asking for that for the coming cycle, though - I'm going to try
        and get conversion of i_mutex to rwsem with ->lookup() done under lock
        taken shared.
        There will be a patch closer to the end of the window, along the lines
        of the one Linus had posted last May - mechanical conversion of
        ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
        inode_is_locked()/inode_lock_nested().  To quote Linus back then:
          |    This is an automated patch using
          |        sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
          |        sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
          |        sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[     ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
          |        sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
          |        sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
          |    with a very few manual fixups
        I'm going to send that once the ->i_mutex-affecting stuff in -next

       "Updates for the component helper merged last year.
        This update removes the old add_components method of detecting and

        I checked during the 4.4-rc cycle, there were no users of the old
        interfaces, as has been the case for some time now.  Breakage due to
        conflicting development is possible, in which case this pull will have
        to be reverted - however, these changes have been in linux-next since
        Dec 7th without any problems reported.
        Removal of that then allows us to change the way we track components
        internally, allowing us to release data that has been used for
        matching at the appropriate time, thereby allowing any resource leaks
        caused by that missing functionality to be resolved"

       "Here is the core arm64 queue for 4.5.  As you might expect, the
        Christmas break resulted in a number of patches not making the final

        useful stuff here, however, and it's detailed below.
        The EFI changes have been Reviewed-by Matt and the memblock change got
        an "OK" from akpm.
         - Support for a separate IRQ stack, although we haven't reduced the
           size of our thread stack just yet since we don't have enough data
           to determine a safe value
         - Refactoring of our EFI initialisation and runtime code into
           drivers/firmware/efi/ so that it can be reused by arch/arm/.
         - Ftrace improvements when unwinding in the function graph tracer
         - Document our silicon errata handling process

      Huaitong Han authored
      vmx_cpuid_tries to update SECONDARY_VM_EXEC_CONTROL in the VMCS, but
      it will cause a vmwrite error on older CPUs because the code does not
      check for the presence of CPU_BASED_ACTIVATE_SECONDARY_CONTROLS.
      This will get rid of the following trace on e.g. Core2 6600:

      Pull LED subsystem updates from Jacek Anaszewski:
       "Besides regular driver updates, we introduce a portion of LED core
        improvements, that allow to avoid the need for using work queues in
        the LED class drivers, that set brightness in a blocking way.
        Affected LED class drivers are being optimized accordingly.
         - LED core improvements:
              - use EXPORT_SYMBOL_GPL consistently,
              - add two new LED_BLINK_ flags,
              - rename brightness_set_sync op to brightness_set_blocking,
              - add led_set_brightness_nosleep{nopm} functions,
              - use set_brightness_work for the blocking op,
              - drivers shouldn't enforce SYNC/ASYNC brightness setting,
              - turn off the LED and wait for completion on unregistering LED
                class device,
              - add managed version of led_trigger_register,
              - add description of brightness setting API to the LED class doc.
         - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520,
              leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532,

              leds-lm355x, leds-ns2.
         - Replace brightness_set op with a new brightness_set_blocking op to
           make the drivers compatible with led triggers: leds-ipaq-micro,
         - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693.
         - Make the driver explicitly non-modular: ledtrig-cpu,
           ledtrig-ide-disk, leds-syscon.
         - Improvements to leds-bcm6328:
              - reuse bcm6328_led_set() instead of copying its functionality,
              - swap LED ON and OFF definitions,
              - improve blink support,
              - simplify duplicated unlock in bcm6328_blink_set,
              - add little endian support,
              - remove unneded lock when checking initial LED status,
              - add HAS_IOMEM dependency,
              - code cleaning.
         - Improvements to leds-bcm6358:
              - use bcm6358_led_set() in order to get rid of the lock,
              - merge bcm6358_led_mode and bcm6358_led_set,

              - remove unneeded busy status check.
         - Call led_pwm_set() in leds-pwm to enforce default LED_OFF.
         - Fix duration to be msec instead of jiffies: ledtrig-transient.
         - Removing NULL check: leds-powernv.
         - Use platform_register/unregister_drivers(): leds-sunfire.
         - Fix module license specification: ledtrig-oneshot.
         - Fix driver description and make license match the header: leds-pwm.
         - Remove checking for state < 1 in flash_strobe_store():

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control patches for the v4.5 series.
        Notably I have a patch to driver core from Stephen Boyd in the pull
        request, this has been ACKed by Greg so it should be OK.  The internal
        API needed some tweaking to allow modular Qualcomm pin controllers.
        There is a bit of development history in here but it should all add up
        nicely and has boiled in linux-next.  For example I merged in v4.4-rc5
        to get rid of some nasty merge conflicts.
         - New drivers:
            - PXA2xx pin controller support
            - Broadcom NSP pin controller support
         - New subdrivers:
            - Samsung EXYNOS5410 support
            - Qualcomm MSM8996 support
            - Qualcomm PM8994 support

            - Allwinner sunxi H3 support
            - Allwinner sunxi A80 support
            - Rockchip RK3228 support
         - Rename the Cygnus pinctrl driver to "iproc" as it is more generic
           than was originally thought.
         - A bunch of Lantiq/Xway updates especially from the OpenWRT people.
         - Several refactorings for the Super-H SH PFC pin controllers.
           Adding SCIF_CLK support.
         - Several fixes to the Atlas 7 driver.
         - Various fixes all over the place"

       "The main changes in this cycle were:
         - introduce optimized single IPI sending methods on modern APICs
           (Linus Torvalds, Thomas Gleixner)
         - kexec/crash APIC handling fixes and enhancements (Hidehiro Kawai)
         - extend lapic vector saving/restoring to the CMCI (MCE) vector as
           well (Juergen Gross)
         - various fixes and enhancements (Jake Oshins, Len Brown)"
