Merge in arm64 fixes queued for 6.7 so that kpti_install_ng_mappings()
can be updated to use arm64_kernel_unmapped_at_el0() instead of checking
the ARM64_UNMAP_KERNEL_AT_EL0 CPU capability directly.

* for-next/fixes:
  arm64: mm: Always make sw-dirty PTEs hw-dirty in pte_modify
  perf/arm-cmn: Fail DTC counter allocation correctly
  arm64: Avoid enabling KPTI unnecessarily
