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
