| |
Linus, please merge this batch of updates for other-than-MM subsystems.
These things missed the first round of updates as I was awaiting clarification of readiness and of the consequences of the additional warnings Arnd is enabling.
Thanks.
The following changes since commit eb6a9339efeb6f3d2b5c86fdf2382cdc293eca2c:

nilfs2: make block erasure safe in nilfs_finish_roll_forward() (2024-05-19 14:36:21 -0700)
---------------------------------------------------------------- - A series ("kbuild: enable more warnings by default") from Arnd Bergmann which enables a number of additional build-time warnings. We fixed all the fallout which we could find, there may still be a few stragglers.
- Samuel Holland has developed the series "Unified cross-architecture kernel-mode FPU API". This does a lot of consolidation of per-architecture kernel-mode FPU usage and enables the use of newer AMD GPUs on RISC-V.
- Tao Su has fixed some selftests build warnings in the series "Selftests: Fix compilation warnings due to missing _GNU_SOURCE definition".
- This pull also includes a nilfs2 fixup from Ryusuke Konishi.
---------------------------------------------------------------- Arnd Bergmann (5): kbuild: turn on -Wextra by default kbuild: remove redundant extra warning flags kbuild: turn on -Wrestrict by default kbuild: enable -Wformat-truncation on clang kbuild: enable -Wcast-function-type-strict unconditionally
Michael Ellerman (1): drm/amd/display: only use hard-float, not altivec on powerpc
Ryusuke Konishi (1): nilfs2: make block erasure safe in nilfs_finish_roll_forward()
Samuel Holland (14): x86/fpu: fix asm/fpu/types.h include guard arch: add ARCH_HAS_KERNEL_FPU_SUPPORT ARM: implement ARCH_HAS_KERNEL_FPU_SUPPORT ARM: crypto: use CC_FLAGS_FPU for NEON CFLAGS arm64: implement ARCH_HAS_KERNEL_FPU_SUPPORT arm64: crypto: use CC_FLAGS_FPU for NEON CFLAGS lib/raid6: use CC_FLAGS_FPU for NEON CFLAGS LoongArch: implement ARCH_HAS_KERNEL_FPU_SUPPORT powerpc: implement ARCH_HAS_KERNEL_FPU_SUPPORT x86: implement ARCH_HAS_KERNEL_FPU_SUPPORT riscv: add support for kernel-mode FPU drm/amd/display: use ARCH_HAS_KERNEL_FPU_SUPPORT selftests/fpu: move FP code to a separate translation unit selftests/fpu: allow building on other architectures
Tao Su (2): Revert "selftests/harness: remove use of LINE_MAX" selftests/harness: use 1024 in place of LINE_MAX
