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 ] * 'rwonce/rework' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux: compiler_types.h: Use unoptimized __unqual_scalar_typeof for sparse compiler_types.h: Optimize __unqual_scalar_typeof compilation time compiler.h: Enforce that READ_ONCE_NOCHECK() access size is sizeof(long) compiler-types.h: Include naked type in __pick_integer_type() match READ_ONCE: Fix comment describing 2x32-bit atomicity gcov: Remove old GCC 3.4 support arm64: barrier: Use '__unqual_scalar_typeof' for acquire/release macros locking/barriers: Use '__unqual_scalar_typeof' for load-acquire macros READ_ONCE: Drop pointer qualifiers when reading from scalar types READ_ONCE: Enforce atomicity for {READ,WRITE}_ONCE() memory accesses READ_ONCE: Simplify implementations of {READ,WRITE}_ONCE() arm64: csum: Disable KASAN for do_csum() fault_inject: Don't rely on "return value" from WRITE_ONCE() net: tls: Avoid assigning 'const' pointer to non-const pointer netfilter: Avoid assigning 'const' pointer to non-const pointer compiler/gcc: Raise minimum GCC version for kernel builds to 4.8

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 - 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+" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (155 commits) clk: mediatek: Remove ifr{0,1}_cfg_regs structures clk: baikal-t1: remove redundant assignment to variable 'divider' clk: baikal-t1: fix spelling mistake "Uncompatible" -> "Incompatible" dt-bindings: clock: Add a missing include to MMP Audio Clock binding dt: Add bindings for IDT VersaClock 5P49V5925 clk: vc5: Add support for IDT VersaClock 5P49V6965 clk: Add Baikal-T1 CCU Dividers driver clk: Add Baikal-T1 CCU PLLs driver dt-bindings: clk: Add Baikal-T1 CCU Dividers binding dt-bindings: clk: Add Baikal-T1 CCU PLLs binding clk: mediatek: assign the initial value to clk_init_data of mtk_mux clk: mediatek: Add MT6765 clock support clk: mediatek: add mt6765 clock IDs dt-bindings: clock: mediatek: document clk bindings vcodecsys for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings mipi0a for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings for Mediatek MT6765 SoC CLK: HSDK: CGU: add support for 148.5MHz clock CLK: HSDK: CGU: support PLL bypassing CLK: HSDK: CGU: check if PLL is bypassed first clk: clk-si5341: Add support for the Si5345 series ...

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. Reported-by:

__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.
