Perf and PMUs:
- Support for the "Rainier" CPU PMU from Arm
- Preparatory driver changes and cleanups that pave the way for BRBE
support
- Support for partial virtualisation of the Apple-M1 PMU
- Support for the second event filter in Arm CSPMU designs
- Minor fixes and cleanups (CMN and DWC PMUs)
- Enable EL2 requirements for FEAT_PMUv3p9
Power, CPU topology:
- Support for AMUv1-based average CPU frequency
- Run-time SMT control wired up for arm64 (CONFIG_HOTPLUG_SMT). It adds
a generic topology_is_primary_thread() function overridden by x86 and
powerpc
New(ish) features:
- MOPS (memcpy/memset) support for the uaccess routines
Security/confidential compute:
- Fix the DMA address for devices used in Realms with Arm CCA. The
CCA architecture uses the address bit to differentiate between shared
and private addresses
- Spectre-BHB: assume CPUs Linux doesn't know about vulnerable by
default
Memory management clean-ups:
- Drop the P*D_TABLE_BIT definition in preparation for 128-bit PTEs
- Some minor page table accessor clean-ups
- PIE/POE (permission indirection/overlay) helpers clean-up
Kselftests:
- MTE: skip hugetlb tests if MTE is not supported on such mappings and
user correct naming for sync/async tag checking modes
Miscellaneous:
- Add a PKEY_UNRESTRICTED definition as 0 to uapi (toolchain people
request)
- Sysreg updates for new register fields
- CPU type info for some Qualcomm Kryo cores

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"Nothing major this time around.
Apart from the usual perf/PMU updates, some page table cleanups, the
notable features are average CPU frequency based on the AMUv1
counters, CONFIG_HOTPLUG_SMT and MOPS instructions (memcpy/memset) in
the uaccess routines.
Perf and PMUs:
- Support for the 'Rainier' CPU PMU from Arm
- Preparatory driver changes and cleanups that pave the way for BRBE
support
- Support for partial virtualisation of the Apple-M1 PMU
- Support for the second event filter in Arm CSPMU designs
- Minor fixes and cleanups (CMN and DWC PMUs)
- Enable EL2 requirements for FEAT_PMUv3p9
Power, CPU topology:
- Support for AMUv1-based average CPU frequency
- Run-time SMT control wired up for arm64 (CONFIG_HOTPLUG_SMT). It
adds a generic topology_is_primary_thread() function overridden by
x86 and powerpc
