      Pull power management and ACPI fixes from Rafael Wysocki:
       "These are two reverts of recent PCI-related ACPI core changes (one of
        which caused some systems to crash on boot and the other was a cleanup
        on top of it) and a devfreq fix for Tegra.
      
        Specifics:
      
         - Revert an ACPI core change related to IRQ management in PCI that
           introduced code relying on the use of kmalloc() which turned out to
           also run during early init when that's not available yet and caused
           some systems to crash on boot for this reason along with a cleanup
           on top of it (Rafael Wysocki).
      
         - Prevent devfreq from flooding the kernel log with useless messages
           on Tegra (which started to happen after some recent changes in the
           devfreq core) by fixing the driver to follow the documentation and
           the core's expectations in its ->target callback (Tomeu Vizoso)"

      ALSA: hda - Loop interrupt handling until really cleared · 473f4145
      Takashi Iwai authored
      Currently the interrupt handler of HD-audio driver assumes that no irq
      update is needed while processing the irq.  But in reality, it has
      been confirmed that the HW irq is issued even during the irq
      handling.  Since we clear the irq status at the beginning, process the
      interrupt, then exits from the handler, the lately issued interrupt is
      left untouched without being properly processed.
      
      This patch changes the interrupt handler code to loop over the
      check-and-process.  The handler tries repeatedly as long as the IRQ
      status are turned on, and either stream or CORB/RIRB is handled.
      
      For checking the stream handling, snd_hdac_bus_handle_stream_irq()
      returns a value indicating the stream indices bits.  Other than that,
      the change is only in the irq handler itself.

      Pull tracing fix from Steven Rostedt:
       "Another small bug reported to me by Chunyu Hu.
      
        When perf added a "reg" function to the function tracing event (not a
        tracepoint), it caused that event to be displayed as a tracepoint and
        could cause errors in tracepoint handling.  That was solved by adding
        a flag to ignore ftrace non-tracepoint events.  But that flag was
        missed when displaying events in available_events, which should only
        contain tracepoint events.
      
        This broke a documented way to enable all events with:
      
            cat available_events > set_event
      
        As the function non-tracepoint event would cause that to error out.
        The commit here fixes that by having the available_events file not
        list events that have the ignore flag set"

      Pull libnvdimm fixes from Dan Williams:
      
       - Two fixes for compatibility with the ACPI 6.1 specification.
      
         Without these fixes multi-interface DIMMs will fail to be probed, and
         address range scrub commands to find memory errors will give results
         that the kernel will mis-interpret.  For multi-interface DIMMs Linux
         will accept either the original 6.0 implementation or 6.1.
      
         For address range scrub we'll only support 6.1 since ACPI formalized
         this DSM differently than the original example [1] implemented in
         v4.2.  The expectation is that production systems will only ever ship
         the ACPI 6.1 address range scrub command definition.
      
       - The wider async address range scrub work targeting 4.6 discovered
         that the original synchronous implementation in 4.5 is not sizing its
         return buffer correctly.
      
       - Arnd caught that my recent fix to the size of the pfn_t flags missed
         updating the flags variable used in the pmem driver.
      
       - Toshi found that we mishandle the memremap() return value in
         devm_memremap().

      Takashi Iwai authored
      HP EliteBook 755 G2 with ALC3228 (ALC280) codec [103c:221c] requires
      the known fixup (ALC269_FIXUP_HEADSET_MIC) for making the headset mic
      working.  Also, it suffers from the loopback noise problem, so we
      should disable aamix path as well.

      ALSA: hda - Fixing background noise on Dell Inspiron 3162 · 3b43b71f
      Kai-Heng Feng authored
      After login to the desktop on Dell Inspiron 3162,
      there's a very loud background noise comes from the builtin speaker.
      The noise does not go away even if the speaker is muted.
      
      The noise disappears after using the aamix fixup.

      This can happen under some annoying circumstances, and is a quick fix
      until more substantial changes can be made.
      
      Fixed eDP mode changes on (at least) the Lenovo P50.

      drivers: sh: Restore legacy clock domain on SuperH platforms · 0378ba48
      Geert Uytterhoeven authored
      CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms
      (which are DT based and multi-platform), but also on a select set of
      Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence
      since commit 0ba58de2 ("drivers: sh: Get rid of
      CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer
      installed on these SuperH platforms, and module clocks may not be
      enabled when needed, leading to driver failures.
      
      To fix this, add an additional check for CONFIG_OF.
      
      Fixes: 0ba58de2 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI").
