For this series, and the series that it sits on top of (i.e.,
https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=kvm-arm64/vgic-lr-overflow-fixes):

Tested-by: Fuad Tabba <tabba at google.com>

On QEMU, nVHE, hVHE protected mode, and protected VMs (with the latest
Android pKVM patches applied on top).
