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.

  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()
