      Pull power management and ACPI fixes from Rafael Wysocki:
       "Three regression fixes this time, one for a recent regression in the
        cpuidle core affecting multiple systems, one for an inadvertently
        added duplicate typedef in ACPICA that breaks compilation with GCC 4.5
        and one for an ACPI Smart Battery Subsystem driver regression
        introduced during the 3.18 cycle (stable-candidate).
      
        Specifics:
      
         - Fix for a regression in the cpuidle core introduced by one of the
           recent commits in the clockevents_notify() removal series that put
           a call to a function which had to be executed with disabled
           interrupts into a code path running with enabled interrupts (Rafael
           J Wysocki)
      
         - Fix for a build problem in ACPICA (with GCC 4.5) introduced by one
           of the recent ACPICA tools commits that added a duplicate typedef
           to one of the ACPICA's header files by mistake (Olaf Hering)
      
         - Fix for a regression in the ACPI SBS (Smart Battery Subsystem)
           driver introduced during the 3.18 development cycle causing the
           smart battery manager to be marked as not present when it should be
           marked as present (Chris Bainbridge)"

      Pull sound fixes from Takashi Iwai:
       "One nice fix is Peter's patch to make the old good SB Audigy PCI to
        work with 32bit DMA instead of 31bit.  This allows the MIDI synth
        running on modern machines again.  Along with it, a few fixes for
        emu10k1 have merged.
      
        In ASoC side, there is one fix in the common code, but it's just
        trivial additions of static inline functions for CONFIG_PM=n.  The
        rest are various device-specific small fixes.
      
        Last but not least, a few HD-audio fixes are included, as usual, too"

      ASoC: Fixes for v4.1
      
      A few fixes for v4.1, none earth shattering and mostly driver related
      except for one change to fix !PM builds for Intel platforms which is
      done by adding stubs in the core so other platforms don't run into the
      same issue.

      dm: fix free_rq_clone() NULL pointer when requeueing unmapped request · aa6df8dd
      Mike Snitzer authored
      Commit 02233342 ("dm: optimize dm_mq_queue_rq to _not_ use kthread if
      using pure blk-mq") mistakenly removed free_rq_clone()'s clone->q check
      before testing clone->q->mq_ops.  It was an oversight to discontinue
      that check for 1 of the 2 use-cases for free_rq_clone():
      1) free_rq_clone() called when an unmapped original request is requeued
      2) free_rq_clone() called in the request-based IO completion path
      
      The clone->q check made sense for case #1 but not for #2.  However, we
      cannot just reinstate the check as it'd mask a serious bug in the IO
      completion case #2 -- no in-flight request should have an uninitialized
      request_queue (basic block layer refcounting _should_ ensure this).
      
      The NULL pointer seen for case #1 is detailed here:
      https://www.redhat.com/archives/dm-devel/2015-April/msg00160.html
      
      Fix this free_rq_clone() NULL pointer by simply checking if the
      mapped_device's type is DM_TYPE_MQ_REQUEST_BASED (clone's queue is
      blk-mq) rather than checking clone->q->mq_ops.  This avoids the need to
      dereference clone->q, but a WARN_ON_ONCE is added to let us know if an
      uninitialized clone request is being completed.

      dm: only initialize the request_queue once · 3e6180f0
      Christoph Hellwig authored
      Commit bfebd1cd ("dm: add full blk-mq support to request-based DM")
      didn't properly account for the need to short-circuit re-initializing
      DM's blk-mq request_queue if it was already initialized.
      
      Otherwise, reloading a blk-mq request-based DM table (either manually
      or via multipathd) resulted in errors, see:
       https://www.redhat.com/archives/dm-devel/2015-April/msg00132.html
      
      Fix is to only initialize the request_queue on the initial table load
      (when the mapped_device type is assigned).
      
      This is better than having dm_init_request_based_blk_mq_queue() return
      early if the queue was already initialized because it elevates the
      constraint to a more meaningful location in DM core.  As such the
      pre-existing early return in dm_init_request_based_queue() can now be
      removed.
