Applied to arm64 (for-next/vcpu-hotplug), thanks! If nothing falls
apart, it should end up in mainline for 6.11.

Thomas, the GICv3 patches have been acked by Marc but they are missing
your ack. If you want it added, I can refresh the series in the next day
or so, otherwise the branch should remain stable. Thanks.
