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

Pull arm64 updates from Will Deacon:
 "We've got a little less than normal thanks to the holidays in
  December, but there's the usual summary below. The highlight is
  probably the 52-bit physical addressing (LPA2) clean-up from Ard.

  Confidential Computing:

   - Register a platform device when running in CCA realm mode to enable
     automatic loading of dependent modules

  CPU Features:

   - Update a bunch of system register definitions to pick up new field
     encodings from the architectural documentation

   - Add hwcaps and selftests for the new (2024) dpISA extensions

  Documentation:

   - Update EL3 (firmware) requirements for booting Linux on modern
     arm64 designs

   - Remove stale information about the kernel virtual memory map

  Miscellaneous:

   - Minor cleanups and typo fixes

  Memory management:

   - Fix vmemmap_check_pmd() to look at the PMD type bits

   - LPA2 (52-bit physical addressing) cleanups and minor fixes

   - Adjust physical address space depending upon whether or not LPA2 is
     enabled

  Perf and PMUs:

   - Add port filtering support for NVIDIA's NVLINK-C2C Coresight PMU

   - Extend AXI filtering support for the DDR PMU on NXP IMX SoCs

   - Fix Designware PCIe PMU event numbering

   - Add generic branch events for the Apple M1 CPU PMU

   - Add support for Marvell Odyssey DDR and LLC-TAD PMUs

   - Cleanups to the Hisilicon DDRC and Uncore PMU code

   - Advertise discard mode for the SPE PMU

   - Add the perf users mailing list to our MAINTAINERS entry"
