Linus Torvalds 542034175c arm64 updates for 6.6
CPU features and system registers:
 	* Advertise hinted conditional branch support (FEAT_HBC) to
 	  userspace
 
 	* Avoid false positive "SANITY CHECK" warning when xCR registers
 	  differ outside of the length field
 
 Documentation:
 	* Fix macro name typo in SME documentation
 
 Entry code:
 	* Unmask exceptions earlier on the system call entry path
 
 Memory management:
 	* Don't bother clearing PTE_RDONLY for dirty ptes in
 	  pte_wrprotect() and pte_modify()
 
 Perf and PMU drivers:
 	* Initial support for Coresight TRBE devices on ACPI systems (the
 	  coresight driver changes will come later)
 
 	* Fix hw_breakpoint single-stepping when called from bpf
 
 	* Fixes for DDR PMU on i.MX8MP SoC
 
 	* Add NUMA-awareness to Hisilicon PCIe PMU driver
 
 	* Fix locking dependency issue in Arm DMC620 PMU driver
 
 	* Workaround Hisilicon erratum 162001900 in the SMMUv3 PMU driver
 
 	* Add support for Arm CMN-700 r3 parts to the CMN PMU driver
 
 	* Add support for recent Arm Cortex CPU PMUs
 
 	* Update Hisilicon PMU maintainers
 
 Selftests:
 	* Add a bunch of new features to the hwcap test (JSCVT, PMULL,
 	  AES, SHA1, etc)
 
 	* Fix SSVE test to leave streaming-mode after grabbing the
 	  signal context
 
 	* Add new test for SVE vector-length changes with SME enabled
 
 Miscellaneous:
 	* Allow compiler to warn on suspicious looking system register
 	  expressions
 
 	* Work around SDEI firmware bug by aborting any running
 	  handlers on a kernel crash
 
 	* Fix some harmless warnings when building with W=1
 
 	* Remove some unused function declarations
 
 	* Other minor fixes and cleanup
