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
