Changes are all over the map, but the big ticket items are the S2 host isolation when running in protected mode, the save/restore support for GICv4.1 and guest SVE support in nVHE mode. Plenty of fixes too. Note that this pull request drags a number of branches from other trees in order to avoid conflicts and make people's life easier: - the Coresight ETE/TRBE branch, as it is intertwined with the KVM tracing support - the arm64 vhe-only branch that deals with broken CPUs such as the Apple M1 - the arm64 neon-softirqs-disabled that improves the support for FP processing You will still get a couple of conflicts with the KVM tree, but these are absolutely trivial to resolve. Please pull, M. The following changes since commit 1e28eed17697bcf343c6743f0028cc3b5dd88bf0: Linux 5.12-rc3 (2021-03-14 14:41:02 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-5.13 for you to fetch changes up to 9a8aae605b80fc0a830cdce747eed48e11acc067: Merge branch 'kvm-arm64/kill_oprofile_dependency' into kvmarm-master/next (2021-04-22 13:41:49 +0100) ---------------------------------------------------------------- KVM/arm64 updates for Linux 5.13 New features: - Stage-2 isolation for the host kernel when running in protected mode - Guest SVE support when running in nVHE mode - Force W^X hypervisor mappings in nVHE mode - ITS save/restore for guests using direct injection with GICv4.1 - nVHE panics now produce readable backtraces - Guest support for PTP using the ptp_kvm driver - Performance improvements in the S2 fault handler - Alexandru is now a reviewer (not really a new feature...) Fixes: - Proper emulation of the GICR_TYPER register - Handle the complete set of relocation in the nVHE EL2 object - Get rid of the oprofile dependency in the PMU code (and of the oprofile body parts
