* 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

Pull arm64 updates from Catalin Marinas:
"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).

in the removal of the cpus_have_const_cap() function and migrating
the code to "alternative" branches where possible
