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.
