      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

        mvebu:
      	fix QNAP TS219 power-off in dts
      	fix legacy get_irqnr_and_base for dove and orion5x

      	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

      Pull more power management and ACPI fixes from Rafael Wysocki:
       "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)"

         generation roll-overs

      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.

       "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"

      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().

      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.

      arm64: efi: correctly map runtime regions · 3b12acf4
      Mark Rutland authored
      The kernel may use a page granularity of 4K, 16K, or 64K depending on
      configuration.
      
      When mapping EFI runtime regions, we use memrange_efi_to_native to round
      the physical base address of a region down to a kernel page boundary,
      and round the size up to a kernel page boundary, adding the residue left
      over from rounding down the physical base address. We do not round down
      the virtual base address.
      
      In __create_mapping we account for the offset of the virtual base from a
      granule boundary, adding the residue to the size before rounding the
      base down to said granule boundary.
      
      Thus we account for the residue twice, and when the residue is non-zero
      will cause __create_mapping to map an additional page at the end of the
      region. Depending on the memory map, this page may be in a region we are
      not intended/permitted to map, or may clash with a different region that
      we wish to map. In typical cases, mapping the next item in the memory
      map will overwrite the erroneously created entry, as we sort the memory
      map in the stub.
      
      As __create_mapping can cope with base addresses which are not page
      aligned, we can instead rely on it to map the region appropriately, and
      simplify efi_virtmap_init by removing the unnecessary code.

      arm64: mm: fix fault_info table xFSC decoding · c03784ee
      Mark Rutland authored
      We are missing descriptions for some valid xFSC values in the fault info
      table (e.g. "TLB conflict abort"), and have erroneous descriptions for
      reserved values (e.g. "asynchronous external abort", "debug event").
      
      This patch adds the missing xFSC values, and removes erroneous decoding
      of values reserved by the architecture, as described in ARM DDI 0487A.h.
      
      At the same time, fixed the unbalanced brackets for the synchronous
      parity error strings in the table.
