2022-11-14ARM: 9259/1: stacktrace: Convert stacktrace to generic ARCH_STACKWALKLi Huafei
Historically architectures have had duplicated code in their stack trace implementations for filtering what gets traced. In order to avoid this duplication some generic code has been provided using a new interface arch_stack_walk(), enabled by selecting ARCH_STACKWALK in Kconfig, which factors all this out into the generic stack trace code. Convert ARM to use this common infrastructure. When initializing the stack frame of the current task, arm64 uses __builtin_frame_address(1) to initialize the frame pointer, skipping arch_stack_walk(), see the commit c607ab4f916d ("arm64: stacktrace: don't trace arch_stack_walk()"). Since __builtin_frame_address(1) does not work on ARM, unwind_frame() is used to unwind the stack one layer forward before calling walk_stackframe().

There are some Dell SKUs that need to set the parameters of the crossover filter (biquad). Each amplifier connects to one tweeter speaker and one woofer speaker.

If the codec driver got the BQ parameters from the device property, it will apply these parameters to the hardware.
2022-11-11crypto: move gf128mul library into lib/cryptoArd Biesheuvel
The gf128mul library does not depend on the crypto API at all, so it can be moved into lib/crypto. This will allow us to use it in other library code in a subsequent patch without having to depend on CONFIG_CRYPTO. While at it, change the Kconfig symbol name to align with other crypto library implementations. However, the source file name is retained, as it is reflected in the module .ko filename, and changing this might break things for users.

2022-11-10ARM: dts: bcm283x: Remove bcm2835-rpi-common.dtsi from SoC DTSIMaxime Ripard
According to the commit log of the commit 3ac395a5b3f3 ("ARM: dts: bcm283x: Use firmware PM driver for V3D"), the initial intent behind the bcm2835-rpi-common DTSI was to share data between the RaspberryPies based on the BCM2835, 36 and 37. However, it was included by these SoCs' main DTSI. This is creating an improper layering. On top of that, bcm2835.dtsi is being included by bcm2711.dtsi, which means that, even though the bcm2835-rpi-common DTSI wasn't actually meant to contain data for the BCM2711, it actually leaks into the BCM2711 DTSI. In order to remove both issues, let's remove the include of bcm2835-rpi-common.dtsi from bcm283{5-7}.dtsi and put them into the bcm283{6,7}-rpi.dtsi. BCM2835 has to be handled with special care due to the fact that bcm2835.dtsi is being included by bcm2711.dtsi. Thus, we chose to include bcm2835-rpi-common.dtsi directly into the board DTS. This will be more error-prone, but given that it's a fairly old SoC by now, the chance that we will get more BCM2835 boards is fairly low. BCM2711 isn't modified since the content of bcm2835-rpi-common.dtsi was only a power-domain for the v3d that was overridden anyway.

2022-11-08ARM: 9258/1: stacktrace: Make stack walk callback consistent with generic codeLi Huafei
As with the generic arch_stack_walk() code the ARM stack walk code takes a callback that is called per stack frame. Currently the ARM code always passes a struct stackframe to the callback and the generic code just passes the pc, however none of the users ever reference anything in the struct other than the pc value. The ARM code also uses a return type of int while the generic code uses a return type of bool though in both cases the return value is a boolean value and the sense is inverted between the two. In order to reduce code duplication when ARM is converted to use arch_stack_walk() change the signature and return sense of the ARM specific callback to match that of the generic code.

2022-11-08ARM: 9265/1: pass -march= only to compilerNick Desaulniers
When both -march= and -Wa,-march= are specified for assembler or assembler-with-cpp sources, GCC and Clang will prefer the -Wa,-march= value but Clang will warn that -march= is unused. warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] This is the top group of warnings we observe when using clang to assemble the kernel via `ARCH=arm make LLVM=1`. Split the arch-y make variable into two, so that -march= flags only get passed to the compiler, not the assembler. -D flags are added to KBUILD_CPPFLAGS which is used for both C and assembler-with-cpp sources. Clang is trying to warn that it doesn't support different values for -march= and -Wa,-march= (like GCC does, but the kernel doesn't need this) though the value of the preprocessor define __thumb2__ is based on -march=. Make sure to re-set __thumb2__ via -D flag for assembler sources now that we're no longer passing -march= to the assembler. Set it to a different value than the preprocessor would for -march= in case -march= gets accidentally re-added to KBUILD_AFLAGS in the future. Thanks to Ard and Nathan for this suggestion.

GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.
