Linus Torvalds df45da57cb arm64 updates for 6.4
ACPI:
 	* Improve error reporting when failing to manage SDEI on AGDI device
 	  removal
 
 Assembly routines:
 	* Improve register constraints so that the compiler can make use of
 	  the zero register instead of moving an immediate #0 into a GPR
 
 	* Allow the compiler to allocate the registers used for CAS
 	  instructions
 
 CPU features and system registers:
 	* Cleanups to the way in which CPU features are identified from the
 	  ID register fields
 
 	* Extend system register definition generation to handle Enum types
 	  when defining shared register fields
 
 	* Generate definitions for new _EL2 registers and add new fields
 	  for ID_AA64PFR1_EL1
 
 	* Allow SVE to be disabled separately from SME on the kernel
 	  command-line
 
 Tracing:
 	* Support for "direct calls" in ftrace, which enables BPF tracing
 	  for arm64
 
 Kdump:
 	* Don't bother unmapping the crashkernel from the linear mapping,
 	  which then allows us to use huge (block) mappings and reduce
 	  TLB pressure when a crashkernel is loaded.
 
 Memory management:
 	* Try again to remove data cache invalidation from the coherent DMA
 	  allocation path
 
 	* Simplify the fixmap code by mapping at page granularity
 
 	* Allow the kfence pool to be allocated early, preventing the rest
 	  of the linear mapping from being forced to page granularity
 
 Perf and PMU:
 	* Move CPU PMU code out to drivers/perf/ where it can be reused
 	  by the 32-bit ARM architecture when running on ARMv8 CPUs
 
 	* Fix race between CPU PMU probing and pKVM host de-privilege
 
 	* Add support for Apple M2 CPU PMU
 
 	* Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
 	  dynamically, depending on what the CPU actually supports
 
 	* Minor fixes and cleanups to system PMU drivers
 
 Stack tracing:
 	* Use the XPACLRI instruction to strip PAC from pointers, rather
 	  than rolling our own function in C
 
 	* Remove redundant PAC removal for toolchains that handle this in
 	  their builtins
 
 	* Make backtracing more resilient in the face of instrumentation
 
 Miscellaneous:
 	* Fix single-step with KGDB
 
 	* Remove harmless warning when 'nokaslr' is passed on the kernel
 	  command-line
 
 	* Minor fixes and cleanups across the board
