      Pull regulator updates from Mark Brown:
       "Another fairly quiet release, some new drivers with generic handling
        for minor features but nothing that makes a substantial difference
        outside of the subsystem or for most boards:
      
         - support for a bunch of new parameters which are present on enough
           regulators to be worth having generic handling for in the
           framework.
      
         - fixes for some issues with printing constraints during boot which
           should probably have gone in for v4.1 but didn't.
      
         - new drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI
           regulators"

      Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm · 2ad7b44f
      Linus Torvalds authored
      Pull clkdev updates from Russell King:
       "This series addresses some breakage in clkdev caused by a previous
        patch set from the clk tree which introduced per-user clk structures.
        This basically renamed the existing 'struct clk' to 'struct clk_hw',
        and introduced a new 'struct clk'.
      
        This change will break anyone using clk_add_alias() with the common
        clk code enabled.  Thankfully, the intersection of users of
        clk_add_alias() and those using the common clk code is practically
        zero, but this is something which should be fixed to keep the code
        sane.
      
        The problem is that clk_add_alias() does this:
      
              r = clk_get(...);
              l = clkdev_alloc(r, ...);
              clk_put(...);
      
        which causes the alias to store a pointer to 'r', which has been
        freed.
      
        The original patch set tried to work around this problem incorrectly -
        at clk_get() time, it tried to convert the struct clk to a struct
        clk_hw, and then creating a new struct clk from that.  Clearly, if the
        original struct clk has been freed, then we have a use-after-free bug.
      
        We have other places in the tree which do something similar, so this
        series also addresses those locations too.
      
        This series addresses this problem by converting clkdev to store and
        use the clk_hw pointer.  This allows clk_get() to only have to create
        it's per-user struct clk from the clk_hw.  We can also get to the
        desired clk_hw at clk_add_alias() or clk lookup creation time, when
        the struct clk is "alive".
      
        We also perform some cleanups of the code:
      
         - replacing looped calls to clkdev_add() with clkdev_add_table()
      
         - replacing open-coded lookup allocation (which should have been
           using clkdev_alloc()) and subsequent clkdev_add() with
           clkdev_create()
      
         - replacing open-coded clk_add_alias() with clk_add_alias()"

      Pull power management and ACPI updates from Rafael Wysocki:
       "The rework of backlight interface selection API from Hans de Goede
        stands out from the number of commits and the number of affected
        places perspective.  The cpufreq core fixes from Viresh Kumar are
        quite significant too as far as the number of commits goes and because
        they should reduce CPU online/offline overhead quite a bit in the
        majority of cases.
      
        From the new featues point of view, the ACPICA update (to upstream
        revision 20150515) adding support for new ACPI 6 material to ACPICA is
        the one that matters the most as some new significant features will be
        based on it going forward.  Also included is an update of the ACPI
        device power management core to follow ACPI 6 (which in turn reflects
        the Windows' device PM implementation), a PM core extension to support
        wakeup interrupts in a more generic way and support for the ACPI _CCA
        device configuration object.
      
        The rest is mostly fixes and cleanups all over and some documentation
        updates, including new DT bindings for Operating Performance Points.
      
        There is one fix for a regression introduced in the 4.1 cycle, but it
        adds quite a number of lines of code, it wasn't really ready before
        Thursday and you were on vacation, so I refrained from pushing it on
        the last minute for 4.1.
      
        Specifics:
      
         - ACPICA update to upstream revision 20150515 including basic support
           for ACPI 6 features: new ACPI tables introduced by ACPI 6 (STAO,
           XENV, WPBT, NFIT, IORT), changes related to the other tables (DTRM,
           FADT, LPIT, MADT), new predefined names (_BTH, _CR3, _DSD, _LPI,
           _MTL, _PRR, _RDI, _RST, _TFP, _TSN), fixes and cleanups (Bob Moore,
           Lv Zheng).
      
         - ACPI device power management core code update to follow ACPI 6
           which reflects the ACPI device power management implementation in
           Windows (Rafael J Wysocki).
      
         - rework of the backlight interface selection logic to reduce the
           number of kernel command line options and improve the handling of
           DMI quirks that may be involved in that and to make the code
           generally more straightforward (Hans de Goede).
      
         - fixes for the ACPI Embedded Controller (EC) driver related to the
           handling of EC transactions (Lv Zheng).
      
         - fix for a regression related to the ACPI resources management and
           resulting from a recent change of ACPI initialization code ordering
           (Rafael J Wysocki).
      
         - fix for a system initialization regression related to ACPI
           introduced during the 3.14 cycle and caused by running the code
           that switches the platform over to the ACPI mode too early in the
           initialization sequence (Rafael J Wysocki).
      
         - support for the ACPI _CCA device configuration object related to
           DMA cache coherence (Suravee Suthikulpanit).

      Pull gpio updates from Linus Walleij:
       "This is the big bulk of GPIO changes queued for the v4.2 kernel
        series:
      
         - a big set of cleanups to the aged sysfs interface from Johan
           Hovold.  To get these in, v4.1-rc3 was merged into the tree as the
           first patch in that series had to go into stable.  This makes the
           locking much more fine-grained (get rid of the "big GPIO lock(s)"
           and store states in the GPIO descriptors.
      
         - rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value() to
           avoid confusions.
      
         - New drivers for:
            * NXP LPC18xx (currently LPC1850)
            * NetLogic XLP
            * Broadcom STB SoC's
            * Axis ETRAXFS
            * Zynq Ultrascale+ (subdriver)
      
         - ACPI:
            * make it possible to retrieve GpioInt resources from a GPIO
              device using acpi_dev_gpio_irq_get()
            * merge some dependent I2C changes exploiting this.
            * support the ARM X-Gene GPIO standby driver.
      
         - make it possible for the generic GPIO driver to read back the value
           set registers to reflect current status.
      
         - loads of OMAP IRQ handling fixes.
      
         - incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
           PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
      
         - janitorial (constification, checkpatch cleanups)"

         - Lower the NOHZ impact on systems which have NOHZ or timer migration

      Pull x86 core updates from Ingo Molnar:
       "There were so many changes in the x86/asm, x86/apic and x86/mm topics
        in this cycle that the topical separation of -tip broke down somewhat -
        so the result is a more traditional architecture pull request,
        collected into the 'x86/core' topic.
      
        The topics were still maintained separately as far as possible, so
        bisectability and conceptual separation should still be pretty good -
        but there were a handful of merge points to avoid excessive
        dependencies (and conflicts) that would have been poorly tested in the
        end.
      
        The next cycle will hopefully be much more quiet (or at least will
        have fewer dependencies).
      
        The main changes in this cycle were:
      
         * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas
           Gleixner)
      
           - This is the second and most intrusive part of changes to the x86
             interrupt handling - full conversion to hierarchical interrupt
             domains:
      
                [IOAPIC domain]   -----
                                       |
                [MSI domain]      --------[Remapping domain] ----- [ Vector domain ]
                                       |   (optional)          |
                [HPET MSI domain] -----                        |
                                                               |
                [DMAR domain]     -----------------------------
                                                               |
                [Legacy domain]   -----------------------------
      
             This now reflects the actual hardware and allowed us to distangle
             the domain specific code from the underlying parent domain, which
             can be optional in the case of interrupt remapping.  It's a clear
             separation of functionality and removes quite some duct tape
             constructs which plugged the remap code between ioapic/msi/hpet
             and the vector management.
      
           - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt
             injection into guests (Feng Wu)
      
         * x86/asm changes:
      
           - Tons of cleanups and small speedups, micro-optimizations.  This
             is in preparation to move a good chunk of the low level entry
             code from assembly to C code (Denys Vlasenko, Andy Lutomirski,
             Brian Gerst)
      
           - Moved all system entry related code to a new home under
             arch/x86/entry/ (Ingo Molnar)
      
           - Removal of the fragile and ugly CFI dwarf debuginfo annotations.
             Conversion to C will reintroduce many of them - but meanwhile
             they are only getting in the way, and the upstream kernel does
             not rely on them (Ingo Molnar)
      
           - NOP handling refinements. (Borislav Petkov)
      
         * x86/mm changes:
      
           - Big PAT and MTRR rework: making the code more robust and
             preparing to phase out exposing direct MTRR interfaces to drivers -
             in favor of using PAT driven interfaces (Toshi Kani, Luis R
             Rodriguez, Borislav Petkov)
      
           - New ioremap_wt()/set_memory_wt() interfaces to support
             Write-Through cached memory mappings.  This is especially
             important for good performance on NVDIMM hardware (Toshi Kani)
      
         * x86/ras changes:
      
           - Add support for deferred errors on AMD (Aravind Gopalakrishnan)
      
             This is an important RAS feature which adds hardware support for
             poisoned data.  That means roughly that the hardware marks data
             which it has detected as corrupted but wasn't able to correct, as
             poisoned data and raises an APIC interrupt to signal that in the
             form of a deferred error.  It is the OS's responsibility then to
             take proper recovery action and thus prolonge system lifetime as
             far as possible.
      
           - Add support for Intel "Local MCE"s: upcoming CPUs will support
             CPU-local MCE interrupts, as opposed to the traditional system-
             wide broadcasted MCE interrupts (Ashok Raj)
      
           - Misc cleanups (Borislav Petkov)

      HSI: nokia-modem: use flags argument of devm_gpiod_get to set direction · f451e76f
      Uwe Kleine-König authored
      Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions)
      which appeared in v3.17-rc1, the gpiod_get* functions take an additional
      parameter that allows to specify direction and initial value for output.
      
      Use this to simplify the driver. Furthermore this is one caller less
      that stops us making the flags argument to gpiod_get*() mandatory.

      HSI: cmt_speech: fix timestamp interface · 5023a5ca
      Sebastian Reichel authored
      The user interface for timestamps in the new cmt_speech
      driver is broken in multiple ways:
      
      - The layout is incompatible between 32-bit and 64-bit user
        space, because of the size differences in 'struct timespec'.
        This means that the driver can not work when used with 32-bit
        user space on a 64-bit kernel.
      
      - As there are plans to change 32-bit user space to use
        a 64-bit time_t type in the future, it will also be
        incompatible with new 32-bit user space.
      
      - It is using ktime_get_ts under it's deprecated alias
        (do_posix_clock_monotonic_gettime).
      
      To keep support for the user space tools written for this driver (which
      have lived many years out-of-tree), the interface has been hardened to
      unsigned 32-bit values.

      Pull x86 FPU updates from Ingo Molnar:
       "This tree contains two main changes:
      
         - The big FPU code rewrite: wide reaching cleanups and reorganization
           that pulls all the FPU code together into a clean base in
           arch/x86/fpu/.
      
           The resulting code is leaner and faster, and much easier to
           understand.  This enables future work to further simplify the FPU
           code (such as removing lazy FPU restores).
      
           By its nature these changes have a substantial regression risk: FPU
           code related bugs are long lived, because races are often subtle
           and bugs mask as user-space failures that are difficult to track
           back to kernel side backs.  I'm aware of no unfixed (or even
           suspected) FPU related regression so far.
      
         - MPX support rework/fixes.  As this is still not a released CPU
           feature, there were some buglets in the code - should be much more
           robust now (Dave Hansen)"

              modes, just press 'f' to 'freeze/unfreeze' the sampling. (Arnaldo Carvalho de Melo)
      
            - Make Ctrl-C stop processing on TUI, allowing interrupting the load of big
              perf.data files (Namhyung Kim)
      
        'perf probe': (Masami Hiramatsu)
      
            - Support glob wildcards for function name
            - Support $params special probe argument: Collect all function arguments
            - Make --line checks validate C-style function name.
            - Add --no-inlines option to avoid searching inline functions
            - Greatly speed up 'perf probe --list' by caching debuginfo.
            - Improve --filter support for 'perf probe', allowing using its arguments
              on other commands, as --add, --del, etc.
      
        'perf sched':
      
            - Add option in 'perf sched' to merge like comms to lat output (Josef Bacik)
      
        Plus tons of infrastructure work - in particular preparation for
