Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
 "CPU features:

   - Remove ARM64_HAS_NO_HW_PREFETCH copy_page() optimisation for ye
     olde Thunder-X machines

   - Avoid mapping KPTI trampoline when it is not required

   - Make CPU capability API more robust during early initialisation

  Early idreg overrides:

   - Remove dependencies on core kernel helpers from the early
     command-line parsing logic in preparation for moving this code
     before the kernel is mapped

  FPsimd:

   - Restore kernel-mode fpsimd context lazily, allowing us to run
     fpsimd code sequences in the kernel with pre-emption enabled

  KBuild:

   - Install 'vmlinuz.efi' when CONFIG_EFI_ZBOOT=y

   - Makefile cleanups

  LPA2 prep:

   - Preparatory work for enabling the 'LPA2' extension, which will
     introduce 52-bit virtual and physical addressing even with 4KiB
     pages (including for KVM guests).

  Misc:

   - Remove dead code and fix a typo

  MM:

   - Pass NUMA node information for IRQ stack allocations

  Perf:

   - Add perf support for the Synopsys DesignWare PCIe PMU

   - Add support for event counting thresholds (FEAT_PMUv3_TH)
     introduced in Armv8.8

   - Add support for i.MX8DXL SoCs to the IMX DDR PMU driver.

   - Minor PMU driver fixes and optimisations

  RIP VPIPT:

   - Remove what support we had for the obsolete VPIPT I-cache policy

  Selftests:

   - Improvements to the SVE and SME selftests

  Stacktrace:

   - Refactor kernel unwind logic so that it can used by BPF unwinding
     and, eventually, reliable backtracing

  Sysregs:

   - Update a bunch of register definitions based on the latest XML drop
     from Arm"
