[GIT,PULL] arm64 updates for 6.6

  Hi Linus,

Please pull these arm64 updates for 6.6.

I think we have a bit less than usual on the architecture side, but
that's somewhat balanced out by a large crop of perf/PMU driver updates
and extensions to our selftests. Summary in the tag.

Cheers,

Will

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
