        cycle.
      
        Like with GPIO it's a lot of stuff.  If my subsystems are any sign of
        the overall tempo of the kernel v4.3 will be a gigantic diff.
      
      [ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
        we'll see - Linus ]
      
        Core changes:
      
         - It is possible configure groups in debugfs.
      
         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().  This series was
           created by Thomas Gleixner after the problem was observed by
           Russell King.
      
         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.
      
         - Tglx also wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.
      
        Driver feature enhancements:
      
         - Power management support for the SiRF SoC Atlas 7.
      
         - Power down support for the Qualcomm driver.
      
         - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
           in IRQ handlers to play nice with the realtime patch set.
      
         - Rework and new modes handling for Qualcomm SPMI-MPP.
      
         - Pinconf power source config for SH PFC.
      
        New drivers and subdrivers:
      
         - A new driver for Conexant Digicolor CX92755.
      
         - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
           ProXtream2 and PH1-LD6b SoC pin control support.
      
         - Reverse-egineered the S/PDIF settings for the Allwinner sun4i
           driver.
      
         - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
      
         - A new Freescale i.mx6ul subdriver.
      
        Cleanup:
      
         - Remove platform data support in a number of SH PFC subdrivers"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.3 kernel cycle.
      
        There is quite a lot going on in the GPIO subsystem this merge window,
        so the main matter is decribed below.
      
        The hits in other subsystems when making the GPIO flags optional are
        all ACKed by their respective subsystem maintainers.
      
        Core changes:
      
         - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
           of the descriptor calls that did not use the flags argument on the
           end.  This was around for too long and eventually Uwe Kleine-König
           took the time to clean it out and the last users are removed along
           with the macros in this tag.  In several cases the use of flags
           simplifies the code.  For this reason we have (ACKed) patches
           hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
           nail with removing the macros.
      
         - Add a fat document describing how much ready-made GPIO stuff we
           have i the kernel to discourage people from reinventing a square
           wheel in userspace, as so often happens.
      
         - Create a separate lockdep class for each instance of a GPIO IRQ
           chip instead of using one class for all chips, as the current code
           will not work with systems with several GPIO chips doing lockdep
           debugging.
      
         - Protect against driver unloading also when a GPIO line is only used
           as IRQ for the GPIOLIB_IRQCHIP helpers.
      
         - If the GPIO chip has no designated owner, assign the parent device
           driver owner as owner.
      
         - Consolidation of chained IRQ handler install/remove replacing all
           call sites where irq_set_handler_data() and
           irq_set_chained_handler() were done in succession with a combined
           call to irq_set_chained_handler_and_data().
      
           This series was created by Thomas Gleixner after the problem was
           observed by Russell King.
      
         - Tglx also made another series of patches switching
           __irq_set_handler_locked() for irq_set_handler_locked() which is
           way cleaner.
      
         - Tglx and Jiang Liu wrote a good bunch of patches to make use of
           irq_desc_get_xxx() accessors and avoid looking up irq_descs from
           IRQ numbers.  The goal is to get rid of the irq number from the
           handlers in the IRQ flow which is nice.
      
         - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
           This was an ARM specific function that is replaced with the generic
           irq_modify_status() where special flags are actually needed.
      
         - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
           if the pin controller isn't available.  Pretty logical, yet needed
           to be fixed.
      
         - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
           back, then call these instead of the defaults provided by the
           GPIOLIB.
      
         - Fix an undocumented ABI hole: named GPIOs were not properly
           documented.
      
        Driver improvements:
      
         - Add get_direction() support to the generic GPIO driver, it's
           strange that we didn't have that before.
      
         - Make it possible to have input-only GPIO chips using the generic
           GPIO driver.
      
         - Clean out platform data support from the Emma Mobile (EM) driver
      
         - Finegrained runtime PM support for the RCAR driver.
      
         - Support r8a7795 (R-car H3) in the RCAR driver.
      
         - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
      
         - Some consolidation and new support in the MPC8xxx driver, we now
           support MPC5125.
      
         - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
           spinlocks making it work better with the realime patches.
      
         - Interrupt support for the EXTRAXFS GPIO driver.
      
         - Make the ETRAXFS GPIO driver support also ARTPEC-3.
      
         - Interrupt and wakeup support for the BRCMSTB driver, also for
           wakeup from S5 cold boot.
      
         - Mask MXC IRQs during suspend.
      
         - Improve OMAP2 GPIO set_debounce() to work according to spec.
      
         - The VF610 driver handles IRQs properly.
      
        New drivers:
      
         - ZTE ZX GPIO driver"

      Pull MIPS updates from Ralf Baechle:
       "This is the main pull request for 4.3 for MIPS.  Here's the summary:
      
        Three fixes that didn't make 4.2-stable:
      
         - a -Os build might compile the kernel using the MIPS16 instruction
           set but the R2 optimized inline functions in <uapi/asm/swab.h> are
           implemented using 32-bit wide instructions which is invalid.
      
         - a build error in pgtable-bits.h for a particular kernel
           configuration.
      
         - accessing registers of the CM GCR might have been compiled to use
           64 bit accesses but these registers are onl 32 bit wide.
      
        And also a few new bits:
      
         - move the ATH79 GPIO driver to drivers/gpio
      
         - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
           change ATH79 accordingly.
      
         - fix definition of pgprot_writecombine
      
         - add an implementation of dma_map_ops.mmap
      
         - fix alignment of quiet build output for vmlinuz link
      
         - BCM47xx: Use kmemdup rather than duplicating its implementation
      
         - Netlogic: Fix 0x0x prefixes of constants.
      
         - merge Bjorn Helgaas' series to remove most of the weak keywords
           from function declarations.
      
         - CP0 and CP1 registers are best considered treated as unsigned
           values to avoid large values from becoming negative values.
      
         - improve support for the MIPS GIC timer.
      
         - enable common clock framework for Malta and SEAD3.
      
         - a number of improvments and fixes to dump_tlb().
      
         - document the MIPS TLB dump functionality in Magic SysRq.
      
         - Cavium Octeon CN68XX improvments.
      
         - NetLogic improvments.
      
         - irq: Use access helper irq_data_get_affinity_mask.
      
         - handle MSA unaligned accesses.
      
         - a number of R6-related math-emu fixes.
      
         - support for I6400.
      
         - improvments to MSA support.
      
         - add uprobes support.
      
         - move from deprecated __initcall to arch_initcall.
      
         - remove finish_arch_switch().
      
         - IRQ cleanups by Thomas Gleixner.
      
         - migrate to new 'set-state' interface.
      
         - random small cleanups"

      Pull locking and atomic updates from Ingo Molnar:
       "Main changes in this cycle are:
      
         - Extend atomic primitives with coherent logic op primitives
           (atomic_{or,and,xor}()) and deprecate the old partial APIs
           (atomic_{set,clear}_mask())
      
           The old ops were incoherent with incompatible signatures across
           architectures and with incomplete support.  Now every architecture
           supports the primitives consistently (by Peter Zijlstra)
      
         - Generic support for 'relaxed atomics':
      
             - _acquire/release/relaxed() flavours of xchg(), cmpxchg() and {add,sub}_return()
             - atomic_read_acquire()
             - atomic_set_release()
      
           This came out of porting qwrlock code to arm64 (by Will Deacon)
      
         - Clean up the fragile static_key APIs that were causing repeat bugs,
           by introducing a new one:
      
             DEFINE_STATIC_KEY_TRUE(name);
             DEFINE_STATIC_KEY_FALSE(name);
      
           which define a key of different types with an initial true/false
           value.
      
           Then allow:
      
             static_branch_likely()
             static_branch_unlikely()
      
           to take a key of either type and emit the right instruction for the
           case.  To be able to know the 'type' of the static key we encode it
           in the jump entry (by Peter Zijlstra)
      
         - Static key self-tests (by Jason Baron)
      
         - qrwlock optimizations (by Waiman Long)
      
         - small futex enhancements (by Davidlohr Bueso)

      clk_get(dev, NULL) will always refer to the same clock, so it's
      pointless calling this multiple times for the same device.  As we no
      longer have to worry about the cleanup (via use of devm_clk_get()) we
      can simplify sa1111_pcmcia_add() too.

      MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16. · e0d8b2ec
      Yousong Zhou authored
      The nomips16 has to be added both as function attribute and assembler
      directive.
      
      When only function attribute is specified, the compiler will inline the
      function with -Os optimization.  The generated assembly code cannot be
      correctly assembled because ISA mode switch has to be done through jump
      instruction.
      
      When only ".set nomips16" directive is used, the generated assembly code
      will use MIPS32 code for the inline assembly template and MIPS16 for the
      function return.  The compiled binary is invalid:
      
          00403100 <__arch_swab16>:
            403100:   7c0410a0    wsbh    v0,a0
            403104:   e820ea31    swc2    $0,-5583(at)
      
      while correct code should be:
      
          00402650 <__arch_swab16>:
            402650:   7c0410a0    wsbh    v0,a0
