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
