Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:

- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
architectural register (ZT0, for the look-up table feature) that
Linux needs to save/restore

- Include TPIDR2 in the signal context and add the corresponding
kselftests

- Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
(ARM CMN) at probe time

- Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64

- Permit EFI boot with MMU and caches on. Instead of cleaning the
entire loaded kernel image to the PoC and disabling the MMU and
caches before branching to the kernel bare metal entry point, leave
the MMU and caches enabled and rely on EFI's cacheable 1:1 mapping of
all of system RAM to populate the initial page tables

- Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
kernel (the arm32 kernel only defines the values)

- Harden the arm64 shadow call stack pointer handling: stash the shadow
stack pointer in the task struct on interrupt, load it directly from
this structure

- Signal handling cleanups to remove redundant validation of size
information and avoid reading the same data from userspace twice

- Refactor the hwcap macros to make use of the automatically generated
ID registers. It should make new hwcaps writing less error prone

- Further arm64 sysreg conversion and some fixes

- arm64 kselftest fixes and improvements

- Pointer authentication cleanups: don't sign leaf functions, unify
asm-arch manipulation

- Pseudo-NMI code generation optimisations

- Minor fixes for SME and TPIDR2 handling

- Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable,
replace strtobool() to kstrtobool() in the cpufeature.c code, apply
dynamic shadow call stack in two passes, intercept pfn changes in
set_pte_at() without the required break-before-make sequence, attempt
to dump all instructions on unhandled kernel faults

Merge tag 'kvmarm-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 6.3

inconsistencie

Merge tag 'kvmarm-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 6.3

- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place.

- Add support for taking stage-2 access faults in parallel. This was an
accidental omission in the original parallel faults implementation,
but should provide a marginal improvement to machines w/o FEAT_HAFDBS
(such as hardware from the fruit company).

- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception handling
and masking unsupported features for nested guests.

- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM.

- VGIC maintenance interrupt support for the AIC

- Improvements to the arch timer emulation, primarily aimed at reducing
the trap overhead of running nested.

- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems.

- Avoid VM-wide stop-the-world operations when a vCPU accesses its own
redistributor.

- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
in the host.

- Aesthetic and comment/kerneldoc fixes

- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer

This also drags in arm64's 'for-next/sme2' branch, because both it and
the PSCI relay changes touch the EL2 initialization code.

This also drags in a couple of branches to avoid conflicts:

- The shared 'kvm-hw-enable-refactor' branch that reworks
initialization, as it conflicted with the virtual cache topology
changes.

- arm64's 'for-next/sme2' branch, as the PSCI relay changes, as both
touched the EL2 initialization code.
