      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.5 kernel cycle
      
        Core changes:
      
         - Expose pull up/down flags for the GPIO character device to
           userspace.
      
           After clear input from the RaspberryPi and Beagle communities, it
           has been established that prototyping, industrial automation and
           make communities strongly need this feature, and as we want people
           to use the character device, we have implemented the simple pull
           up/down interface for GPIO lines.
      
           This means we can specify that a (chip-specific) pull up/down
           resistor can be enabled, but does not offer fine-grained control
           such as cases where the resistance of the same pull resistor can be
           controlled (yet).
      
         - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
           old symbol devm_fwnode_get_index_gpiod_from_child().
      
         - A bit of documentation clean-up work.
      
         - Introduce a define for GPIO line directions and deploy it in all
           GPIO drivers in the drivers/gpio directory.
      
         - Add a special callback to populate pin ranges when cooperating with
           the pin control subsystem and registering ranges as part of adding
           a gpiolib driver and a gpio_irq_chip driver at the same time. This
           is also deployed in the Intel Merrifield driver.
      
        New drivers:
      
         - RDA Micro GPIO controller.
      
         - XGS-iproc GPIO driver.
      
        Driver improvements:
      
         - Wake event and debounce support on the Tegra 186 driver.
      
         - Finalize the Aspeed SGPIO driver.
      
         - MPC8xxx uses a normal IRQ handler rather than a chained handler"

      Pull clk updates from Stephen Boyd:
       "This merge window we have one small clk provider API in the core
        framework and then a bunch of driver updates and a handful of new
        drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
        high up there because of all the clk data introcued by new drivers.
        The Nvidia Tegra driver had a lot of work done this cycle too to
        support suspend/resume and memory controllers. And the OMAP clk driver
        got proper clk and reset handling in place.
      
        Rounding out the patches are various updates to remove unused data,
        mark things static, correct incorrect data in drivers, etc. All the
        little things that improve drivers and maintain code health. I will
        point out that there's a patch in here for the GPIO clk driver, that
        almost nobody uses, which changes behavior and causes clk_set_rate()
        to try to change the GPIO gate clk's parent. Other than that things
        are fairly well SoC specific here.
      
        Core:
         - Add a clk provider API to get current parent index
         - Plug a memory leak in clk_unregister() path
      
        New Drivers:
         - CGU in Ingenix X1000
         - Bitmain BM1880 clks
         - Qualcomm MSM8998 GPU clk controllers
         - Qualcomm SC7180 GCC and RPMH clk controllers
         - Qualcomm QCS404 Q6SSTOP clk controllers
         - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
         - Add support for the Renesas RZ/G2N (r8a774b1) SoC
         - Add Tegra20/30 External Memory Clock (EMC) support
      
        Updates:
         - Make gpio gate clks propagate rate setting up to parent
         - Prepare Armada 3700 for suspend to RAM by moving PCIe
           suspend/resume priority
         - Drop unused variables, enums, etc. in various clk drivers
         - Convert various drivers to use devm_platform_ioremap_resource()
         - Use struct_size() some more in various clk drivers
         - Improve Rockchip px30 clk tree
         - Add suspend/resume support to Tegra210 clk driver
         - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
         - Allwinner DT exports and H6 clk tree fixes
         - Proper clk and reset handling for OMAP SoCs
         - Revamped TI divider clk to clamp max divider
         - Make 1443X/1416X PLL clock structure common for reusing among i.MX8
           SoCs
         - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
         - Add VIDEO2_PLL clock for imx8mq
         - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
         - Add sm1 support in the Amlogic audio clock controller
         - Switch some clocks on R-Car Gen2/3 to .determine_rate()
         - Remove Renesas R-Car Gen2 legacy DT clock support
         - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
         - Improve Renesas R-Car Gen3 SD clock handling
         - Add rate table for Samsung exynos542x GPU and VPLL clks

        This is a series of cleanups for the y2038 work, mostly intended for
        namespace cleaning: the kernel defines the traditional time_t, timeval
        and timespec types that often lead to y2038-unsafe code. Even though
        the unsafe usage is mostly gone from the kernel, having the types and
        associated functions around means that we can still grow new users,
        and that we may be missing conversions to safe types that actually
        matter.
      
        There are still a number of driver specific patches needed to get the

      Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
       "As part of the cleanup of some remaining y2038 issues, I came to
        fs/compat_ioctl.c, which still has a couple of commands that need
        support for time64_t.
      
        In completely unrelated work, I spent time on cleaning up parts of
        this file in the past, moving things out into drivers instead.
      
        After Al Viro reviewed an earlier version of this series and did a lot
        more of that cleanup, I decided to try to completely eliminate the
        rest of it and move it all into drivers.
      
        This series incorporates some of Al's work and many patches of my own,
        but in the end stops short of actually removing the last part, which
        is the scsi ioctl handlers. I have patches for those as well, but they
        need more testing or possibly a rewrite"

      Pull sysctl system call removal from Eric Biederman:
       "As far as I can tell we have reached the point where no one enables
        the sysctl system call anymore. It still is enabled in a few
        defconfigs but they are mostly the rarely used one and in asking
        people about that it was more cut & paste enabled than anything else.
      
        This is single commit that just deletes code. Leaving just enough code
        so that the deprecated sysctl warning continues to be printed. If my
        analysis turns out to be wrong and someone actually cares it will be
        easy to revert this commit and have the system call again.
      
        There was one new xtensa defconfig in linux-next that enabled the
        system call this cycle and when asked about it the maintainer of the
        code replied that it was not enabled on purpose. As of today's
        linux-next tree that defconfig no longer enables the system call.
      
        What we saw in the review discussion was that if we go a step farther
        than my patch and mess with uapi headers there are pieces of code that
        won't compile, but nothing minds the system call actually disappearing
        from the kernel"

         - Some reworks of the pseries CMM (Cooperative Memory Management)
           driver to make it behave more like other balloon drivers and enable
           some cleanups of generic mm code.
      
         - A series of fixes to our hardware breakpoint support to properly
           handle unaligned watchpoint addresses.
      
        Plus a bunch of other smaller improvements, fixes and cleanups.

      Pull pipe rework from David Howells:
       "This is my set of preparatory patches for building a general
        notification queue on top of pipes. It makes a number of significant
        changes:
      
         - It removes the nr_exclusive argument from __wake_up_sync_key() as
           this is always 1. This prepares for the next step:
      
         - Adds wake_up_interruptible_sync_poll_locked() so that poll can be
           woken up from a function that's holding the poll waitqueue
           spinlock.
      
         - Change the pipe buffer ring to be managed in terms of unbounded
           head and tail indices rather than bounded index and length. This
           means that reading the pipe only needs to modify one index, not
           two.
      
         - A selection of helper functions are provided to query the state of
           the pipe buffer, plus a couple to apply updates to the pipe
           indices.
      
         - The pipe ring is allowed to have kernel-reserved slots. This allows
           many notification messages to be spliced in by the kernel without
           allowing userspace to pin too many pages if it writes to the same
           pipe.
      
         - Advance the head and tail indices inside the pipe waitqueue lock
           and use wake_up_interruptible_sync_poll_locked() to poke poll
           without having to take the lock twice.
      
         - Rearrange pipe_write() to preallocate the buffer it is going to
           write into and then drop the spinlock. This allows kernel
           notifications to then be added the ring whilst it is filling the
           buffer it allocated. The read side is stalled because the pipe
           mutex is still held.
      
         - Don't wake up readers on a pipe if there was already data in it
           when we added more.
      
         - Don't wake up writers on a pipe if the ring wasn't full before we
           removed a buffer"

        pipe: Allow pipes to have kernel-reserved slots
