      Pull READ/WRITE_ONCE rework from Will Deacon:
       "This the READ_ONCE rework I've been working on for a while, which
        bumps the minimum GCC version and improves code-gen on arm64 when
        stack protector is enabled"
      
      [ Side note: I'm _really_ tempted to raise the minimum gcc version to
        4.9, so that we can just say that we require _Generic() support.
      
        That would allow us to more cleanly handle a lot of the cases where we
        depend on very complex macros with 'sizeof' or __builtin_choose_expr()
        with __builtin_types_compatible_p() etc.
      
        This branch has a workaround for sparse not handling _Generic(),
        either, but that was already fixed in the sparse development branch,
        so it's really just gcc-4.9 that we'd require.   - Linus ]

      The proc_kill_sb() does not expect fs_info to be NULL which is wrong.

       "This time around we have four lines of diff in the core framework,
        removing a function that isn't used anymore. Otherwise the main new
        thing for the common clk framework is that it is selectable in the

        consumers be testable on more than the architectures that support the

        framework.
      
        Outside of the core framework we have the usual set of various driver
        updates and non-critical fixes. The dirstat shows that the new
        Baikal-T1 driver is the largest addition this time around in terms of
        lines of code. After that the x86 (Intel), Qualcomm, and Mediatek
        drivers introduce many lines to support new or upcoming SoCs. After
        that the dirstat shows the usual suspects working on their SoC support
        by fixing minor bugs, correcting data and converting some of their DT
        bindings to YAML.
      
        Core:
         - Allow the COMMON_CLK config to be selectable
      
        New Drivers:
         - Clk driver for Baikal-T1 SoCs
         - Mediatek MT6765 clock support
         - Support for Intel Agilex clks

         - Add support for Qualcomm's MSM8939 Generic Clock Controller
      
        Updates:
         - Support IDT VersaClock 5P49V5925
         - Bunch of updates for HSDK clock generation unit (CGU) driver
         - Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs

         - A few patches from Abel Vesa as preparation of adding audiomix
           clock support on i.MX
         - A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and
           clk-pllv3 drivers
         - Drop dependency on ARM64 for i.MX8M clock driver, to support
           aarch32 mode on aarch64 hardware
         - A series from Peng Fan to improve i.MX8M clock drivers, using
           composite clock for core and bus clk slice
         - Set a better parent clock for flexcan on i.MX6UL to support CiA102
           defined bit rates
         - A couple changes for EMC frequency scaling on Tegra210
         - Support for CPU frequency scaling on Tegra20/Tegra30
         - New clk gate for CSI test pattern generator on Tegra210
         - Regression fixes for Samsung exynos542x and exynos5433 SoCs
         - Use of fallthrough; attribute for Samsung s3c24xx
         - Updates and fixup HDMI and video clocks on Meson8b
         - Fixup reset polarity on Meson8b
         - Fix GPU glitch free mux switch on Meson gx and g12
         - A minor fix for the currently unused suspend/resume handling on
           Renesas RZ/A1 and RZ/A2
         - Two more conversions of Renesas DT bindings to json-schema
         - Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+"

      Input: adi - work around module name confict · 751ad34f
      Arnd Bergmann authored
      Making module name conflicts a fatal error breaks sparc64 allmodconfig:
      
      Error log:
      error: the following would cause module name conflict:
        drivers/char/adi.ko
        drivers/input/joystick/adi.ko
      
      Renaming one of the modules would solve the problem, but then cause other
      problems because neither of them is automatically loaded and changing
      the name is likely to break any setup that relies on manually loading
      it by name.
      
      As there is probably no sparc64 system with this kind of ancient joystick
      attached, work around it by adding a Kconfig dependency that forbids
      them from both being modules.  It is still possible to build the joystick
      driver if the sparc64 adi driver is built-in.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added some knobs to enhance compression feature
        and harden testing environment. In addition, we've fixed several bugs
        reported from Android devices such as long discarding latency, device
        hanging during quota_sync, etc.
      
        Enhancements:
         - support lzo-rle algorithm
         - add two ioctls to release and reserve blocks for compression
         - support partial truncation/fiemap on compressed file
         - introduce sysfs entries to attach IO flags explicitly
         - add iostat trace point along with read io stat
      
        Bug fixes:
         - fix long discard latency
         - flush quota data by f2fs_quota_sync correctly
         - fix to recover parent inode number for power-cut recovery
         - fix lz4/zstd output buffer budget
         - parse checkpoint mount option correctly
         - avoid inifinite loop to wait for flushing node/meta pages
         - manage discard space correctly
      
        And some refactoring and clean up patches were added"

      x86: use proper parentheses around new uaccess macro argument uses · 3beff76b
      Linus Torvalds authored
      __get_kernel_nofault() didn't have the parentheses around the use of
      'src' and 'dst' macro arguments, making the casts potentially do the
      wrong thing.
      
      The parentheses aren't necessary with the current very limited use in
      mm/access.c, but it's bad form, and future use-cases might have very
      unexpected errors as a result.
      
      Do the same for unsafe_copy_loop() while at it, although in that case it
      is an entirely internal x86 uaccess helper macro that isn't used
      anywhere else and any other use would be invalid anyway.
      
      Fixes: fa94111d ("x86: use non-set_fs based maccess routines")
