Linus Torvalds 56ec8e4cd8 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

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).

   - 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
