Merge tag 'kvmarm-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
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 at the same time) - Debug and SPE fixes - Fix vcpu reset
