[GIT,PULL] KVM/arm64 updates for 6.3

Paolo, Here's the bulk of the KVM/arm64 updates for 6.3, see the tag for the laundry list. A couple of things to note: - We drag two branches to avoid ugly conflicts: * the common KVM 'kvm-hw-enable-refactor' that you already have in your tree * the arm64 'for-next/sme2' branch - The whole thing has been pulled together by Oliver who has, I think, done a tremendous job Please pull, M. The following changes since commit 5dc4c995db9eb45f6373a956eb1f69460e69e6d4: Linux 6.2-rc4 (2023-01-15 09:22:43 -0600) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-6.3 for you to fetch changes up to 96a4627dbbd48144a65af936b321701c70876026: Merge tag ' https://github.com/oupton/linux tags/kvmarm-6.3' from into kvmarm-master/next (2023-02-18 14:06:10 +0000) ---------------------------------------------------------------- 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 myself as co-maintainer 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.
