Subject: [GIT PULL] arm64 updates for 6.7
Hi Linus,
Here's the main arm64 pull request for 6.7. No major architecture
features this time around, just some new HWCAP definitions, support for
the Ampere SoC PMUs and a few fixes/cleanups. The bulk of the changes is
reworking of the CPU capability checking code (cpus_have_cap() etc).
Thanks.
The following changes since commit 6465e260f48790807eef06b583b38ca9789b6072:

Merge branch 'for-next/cpus_have_const_cap' into for-next/core (2023-10-26 17:10:18 +0100)
----------------------------------------------------------------
arm64 updates for 6.7:
* Major refactoring of the CPU capability detection logic resulting in
the removal of the cpus_have_const_cap() function and migrating the
code to "alternative" branches where possible
* Backtrace/kgdb: use IPIs and pseudo-NMI
* Perf and PMU:
- Add support for Ampere SoC PMUs
- Multi-DTC improvements for larger CMN configurations with multiple
Debug & Trace Controllers
- Rework the Arm CoreSight PMU driver to allow separate registration of
vendor backend modules
- Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf
driver; use device_get_match_data() in the xgene driver; fix NULL
pointer dereference in the hisi driver caused by calling
cpuhp_state_remove_instance(); use-after-free in the hisi driver
* HWCAP updates:
- FEAT_SVE_B16B16 (BFloat16)
- FEAT_LRCPC3 (release consistency model)
- FEAT_LSE128 (128-bit atomic instructions)
* SVE: remove a couple of pseudo registers from the cpufeature code.
There is logic in place already to detect mismatched SVE features
* Miscellaneous:
- Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA
bouncing is needed. The buffer is still required for small kmalloc()
buffers
- Fix module PLT counting with !RANDOMIZE_BASE
- Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move
synchronisation code out of the set_ptes() loop
- More compact cpufeature displaying enabled cores
- Kselftest updates for the new CPU features
