      Pull ARM SoC fixes from Arnd Bergmann:
       "There is a small backlog of at91 patches here, the most significant is
        the addition of some sama5d2 Xplained nodes that were waiting on an
        MFD include file to get merged through another tree.
      
        We normally try to sort those out before the merge window opens, but
        the maintainer wasn't aware of that here and I decided to merge the
        changes this time as an exception.
      
        On OMAP a series of audio changes for dra7 missed the merge window but
        turned out to be necessary to fix a boot time imprecise external abort
        error and to get audio working.
      
        The other changes are the usual simple changes, here is a list sorted
        by platform:
      
        at91:
      	removal of a useless defconfig option
      	removal of some legacy DT pieces
      	use of the proper watchdog compatible string
      	update of the MAINTAINERS entries for some Atmel drivers

              fix linking RAM setup for QMs

        mediatek:
      	Enable SCPSYS power domain driver by default
      
        mvebu:
      	fix QNAP TS219 power-off in dts
      	fix legacy get_irqnr_and_base for dove and orion5x
      
        omap:
      	fix l4 related boot time errors for dm81xx
      	use lockless cldm/pwrdm api in omap4_boot_secondary
      	remove t410 abort handler to avoid hiding other critical errors
      	mark cpuidle tracepoints as _rcuidle
      	fix module alias for omap-ocp2scp
      
        pxa:
      	palm: Fix typos in PWM lookup table code
      
        renesas:
      	missing __initconst annotation for r8a7793_boards_compat_dt
      
        rockchip:
      	disable mmc-tuning on the veyron-minnie board
      	adding the init state for the over-temperature-protection

       "These fix one recent regression (cpufreq core), fix up two features
        added recently (ACPI CPPC support, SCPI support in the arm_big_little
        cpufreq driver) and fix three older bugs in the intel_pstate driver.
      
        Specifics:
      
         - Fix a recent regression in the cpufreq core causing it to fail to
           clean up sysfs directories properly on cpufreq driver removal
           (Viresh Kumar).
      
         - Fix a build problem in the SCPI support code recently added to the
           arm_big_little cpufreq driver (Punit Agrawal).
      
         - Fix up the recently added CPPC cpufreq frontend to process the CPU
           coordination information provided by the platform firmware
           correctly (Ashwin Chaugule).
      
         - Fix the intel_pstate driver to behave as intended when switched
           over to the "performance" mode via sysfs if hardware-driven P-state
           selection (HWP) is enabled (Alexandra Yates).
      
         - Fix two rounding errors in the intel_pstate driver that sometimes
           cause it to use lower P-states than requested (Prarit Bhargava)"

      Merge "The i.MX fixes for 4.4" from Shawn Guo:
      
      - Add missing .irq_set_type for i.MX GPC irq_chip.  It fixes an issue
        that device IRQ type setting doesn't match the one specified in device
        tree, since stacked IRQ domain is adopted in GPC driver.
      - Fix the wrong spi-num-chipselects settings for Vybrid DSPI devices.
      - Fix a merge error in Vybrid dts regarding to ADC device property
        fsl,adck-max-frequency

      intel_pstate: Fix "performance" mode behavior with HWP enabled · 584ee3dc
      Alexandra Yates authored
      If hardware-driven P-state selection (HWP) is enabled, the
      "performance" mode of intel_pstate should only allow the processor
      to use the highest-performance P-state available.  That is not
      the case currently, so make it actually happen.

      Pull more block layer fixes from Jens Axboe:
       "I wasn't going to send off a new pull before next week, but the blk
        flush fix from Jan from the other day introduced a regression.  It's
        rare enough not to have hit during testing, since it requires both a
        device that rejects the first flush, and bad timing while it does
        that.  But since someone did hit it, let's get the revert into 4.4-rc3
        so we don't have a released rc with that known issue.
      
        Apart from that revert, three other fixes:
      
         - From Christoph, a fix for a missing unmap in NVMe request
           preparation.
      
         - An NVMe fix from Nishanth that fixes data corruption on powerpc.
      
         - Also from Christoph, fix a list_del() attempt on blk-mq that didn't
           have a matching list_add() at timer start"
      
      * 'for-linus' of git://git.kernel.dk/linux-block:
        Revert "blk-flush: Queue through IO scheduler when flush not required"
        block: fix blk_abort_request for blk-mq drivers
        nvme: add missing unmaps in nvme_queue_rq

      ARM: OMAP4+: SMP: use lockless clkdm/pwrdm api in omap4_boot_secondary · 918af9f9
      Grygorii Strashko authored
      OMAP CPU hotplug uses cpu1's clocks and power domains for CPU1 wake up
      from low power states (or turn on CPU1). This part of code is also
      part of system suspend (disable_nonboot_cpus()).
      >From other side, cpu1's clocks and power domains are used by CPUIdle. All above
      functionality is mutually exclusive and, therefore, lockless clkdm/pwrdm api
      can be used in omap4_boot_secondary().
      
      This fixes below back-trace on -RT which is triggered by

      arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data · 29f5b34c
      Neil Armstrong authored
      Add missing HWMOD_NO_IDLEST hwmod flag for entries not
      having omap4 clkctrl values.
      The emac0 hwmod flag fixes the davinci_emac driver probe
      since the return of pm_resume() call is now checked.
      
      This solves the following boot errors :
      [    0.121429] omap_hwmod: l4_ls: _wait_target_ready failed: -16
      [    0.121441] omap_hwmod: l4_ls: cannot be enabled for reset (3)

      Thanks for report! After some investigation I found out we allocate
      elevator specific data in __get_request() only for non-flush requests. And
      this is actually required since the flush machinery uses the space in
      struct request for something else. Doh. So my patch is just wrong and not
      easy to fix since at the time __get_request() is called we are not sure
      whether the flush machinery will be used in the end. Jens, please revert
      1b2ff19e. Thanks!
      
      I'm somewhat surprised that you can reliably hit the race where flushing
      gets disabled for the device just while the request is in flight. But I
      guess during boot it makes some sense.
      
      --
      
      So let's just revert it, we can fix the queue run manually after the
      fact. This race is rare enough that it didn't trigger in testing, it
      requires the specific disable-while-in-flight scenario to trigger.
