CPU errata handling:
- Extend CnP disabling workaround to HiSilicon HIP09 hardware.
- Work around eternally broken broadcast TLB invalidation on more CPUs.
- Documentation and code cleanups.
CPU features:
- Add new hwcaps for the 2025 dpISA extensions.
Floating point / SVE / SME:
- Significant cleanup to the low-level state management code in the core
architecture code and KVM.
- Use correct register widths during SVE/SME save/restore assembly.
- Expose SVE/SME save/restore memory accesses to sanitisers.
Memory management:
- Preparatory work for unmapping the kernel data and bss sections from
the linear map.
Miscellaneous:
- Inline DAIF manipulation helpers so they can be used safely from
non-instrumentable code.
- Fix handling of the 'nosmp' cmdline option to avoid marking secondary
cores as "possible".
MPAM:
- Add support for v0.1 of the MPAM architecture.
Perf:
- Update HiSilicon PMU MAINTAINERS entry.
- Fix event encodings for the DVM node in the CMN driver.
Selftests:
- Extend sigframe tests to cover POE context.
- Add coverage for the newly added 2025 dpISA hwcaps.
System registers:
- Add new registers and ESR encodings for the HDBSS feature.
Plus minor fixes and cleanups across the board.

Merge tag 'arm64-upstream' of gitolite.kernel.org:pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"It feels like the new world of AI tooling has slowed us down a little
on the feature side when compared to the fixes side. The extra rounds
of Sashiko review have also pushed a few things out until next time.
Still, there's some good foundational stuff here for the fpsimd code
and hardening work towards removing the predictable linear alias of
the kernel image.
