Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"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.
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"
