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

[ 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 ]

Pull clk updates from Stephen Boyd:
 "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
  Kconfig language now. Hopefully this will let clk drivers and clk
  consumers be testable on more than the architectures that support the
  clk framework. The goal is to introduce some Kunit tests for 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 X1830 and X1000 Ingenic SoC clk controllers
   - Add support for the new Renesas RZ/G1H (R8A7742) SoC
   - 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
   - Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
   - Enable supply regulators for GPU gdscs on Qualcomm SoCs
   - Add support for Si5342, Si5344 and Si5345 chips
   - Support custom flags in Xilinx zynq firmware
   - Various small fixes to the Xilinx clk driver
   - A single minor rounding fix for the legacy Allwinner clock support
   - 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

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

__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.
