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

Pull arm64 updates from Will Deacon:

 - Support for including MTE tags in ELF coredumps

 - Instruction encoder updates, including fixes to 64-bit immediate
   generation and support for the LSE atomic instructions

 - Improvements to kselftests for MTE and fpsimd

 - Symbol aliasing and linker script cleanups

 - Reduce instruction cache maintenance performed for user mappings
   created using contiguous PTEs

 - Support for the new "asymmetric" MTE mode, where stores are checked
   asynchronously but loads are checked synchronously

 - Support for the latest pointer authentication algorithm ("QARMA3")

 - Support for the DDR PMU present in the Marvell CN10K platform

 - Support for the CPU PMU present in the Apple M1 platform

 - Use the RNDR instruction for arch_get_random_{int,long}()

 - Update our copy of the Arm optimised string routines for str{n}cmp()

 - Fix signal frame generation for CPUs which have foolishly elected to
   avoid building in support for the fpsimd instructions

 - Workaround for Marvell GICv3 erratum #38545

 - Clarification to our Documentation (booting reqs. and MTE prctl())

 - Miscellanous cleanups and minor fixes
