        build testing and been run through Fengguang's LKP tests.  Due to
        timing this round, these have not spent any time in linux-next.  I
        have asked Stephen to include my for-next branch in linux-next going
        forward, once he's back from vacation.

      platform/x86: toshiba: re-enable acpi hotkeys after suspend to disk · e7fdb762
      Benjamin Tissoires authored
      On the Toshiba Tecra Z40, after a suspend-to-disk, some FN hotkeys
      driven by toshiba_acpi are not functional.
      
      Calling the ACPI object ENAB on resume makes them back alive.

      ideapad-laptop: Constify DMI table for real! · b3d94d70
      Mathias Krause authored
      This is a follow-up patch to commit 49458e83 ("ideapad-laptop:
      Constify DMI table and other r/o variables") to do what its commit
      message says. The actual commit differs from the patch posted at
      https://www.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05340.html
      significantly, probably due to a bad merge conflict resolution. Fix up
      the mess and constify the DMI table for real and fix the bogus
      double-const of ideapad_rfk_data[].

      Revert "leds: convert blink timer to workqueue" · 9067359f
      Jiri Kosina authored
      This reverts commit 8b37e1be.
      
      It's broken as it changes led_blink_set() in a way that it can now sleep
      (while synchronously waiting for workqueue to be cancelled). That's a
      problem, because it's possible that this function gets called from atomic
      context (tpt_trig_timer() takes a readlock and thus disables preemption).
      
      This has been brought up 3 weeks ago already [1] but no proper fix has
      materialized, and I keep seeing the problem since 3.17-rc1.
      
      [1] https://lkml.org/lkml/2014/8/16/128

      f2fs: reposition unlock_new_inode to prevent accessing invalid inode · b73e5282
      Chao Yu authored
      As the race condition on the inode cache, following scenario can appear:
      [Thread a]				[Thread b]
      					->f2fs_mkdir
      					  ->f2fs_add_link
      					    ->__f2fs_add_link
      					      ->init_inode_metadata failed here
      ->gc_thread_func
        ->f2fs_gc
          ->do_garbage_collect
            ->gc_data_segment
              ->f2fs_iget
                ->iget_locked
                  ->wait_on_inode
      					  ->unlock_new_inode
              ->move_data_page
      					  ->make_bad_inode
      					  ->iput
      
      When we fail in create/symlink/mkdir/mknod/tmpfile, the new allocated inode
      should be set as bad to avoid being accessed by other thread. But in above
      scenario, it allows f2fs to access the invalid inode before this inode was set
      as bad.
      This patch fix the potential problem, and this issue was found by code review.
      
      change log from v1:
       o Add condition judgment in gc_data_segment() suggested by Changman Lee.
       o use iget_failed to simplify code.

      ALC1150 codec seems to need the COEF- and PLL-setups just like its
      compatible ALC882 codec.  Some machines (e.g. SunMicro X10SAT) show
      the problem like too low output volumes unless the COEF setup is
      applied.

      Revert "arm64: cpuinfo: print info for all CPUs" · 5e39977e
      Will Deacon authored
      It turns out that vendors are relying on the format of /proc/cpuinfo,
      and we've even spotted out-of-tree hacks attempting to make it look
      identical to the format used by arch/arm/. That means we can't afford to
      churn this interface in mainline, so revert the recent reformatting of
      the file for arm64 pending discussions on the list to find out what
      people actually want.

      arm64: fix bug for reloading FPSIMD state after cpu power off · 7c68a9cc
      Leo Yan authored
      Now arm64 defers reloading FPSIMD state, but this optimization also
      introduces the bug after cpu resume back from low power mode.
      
      The reason is after the cpu has been powered off, s/w need set the
      cpu's fpsimd_last_state to NULL so that it will force to reload
      FPSIMD state for the thread, otherwise there has the chance to meet
      the condition for both the task's fpsimd_state.cpu field contains the
      id of the current cpu, and the cpu's fpsimd_last_state per-cpu variable
      points to the task's fpsimd_state, so finally kernel will skip to reload
      the context during it return back to userland.

       "Here's the weekly batch of fixes from arm-soc.
      
        The delta is a largeish negative delta, due to revert of SMP support
        for Broadcom's STB SoC -- it was accidentally merged before some
        issues had been addressed, so they will make a new attempt for 3.18.
        I didn't see a need for a full revert of the whole platform due to
        this, we're keeping the rest enabled.
      
        The rest is mostly:
      
         - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
         - some MTD/NAND fixes for OMAP
         - minor DT fixes for shmobile
         - warning fix for UP builds on vexpress/spc
      
        There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
        so it can boot.  Drivers and the rest had landed for 3.17, and it's
        small and isolated so it made sense to pick up now even if it's not a
