arm64 has different capability from x86 to enable the dirty ring, which is KVM_CAP_DIRTY_LOG_RING_ACQ_REL. Besides, arm64 also needs the backup bitmap extension (KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP) when 'kvm-arm-gicv3' or 'arm-its-kvm' device is enabled. Here the extension is always enabled and the unnecessary overhead to do the last stage of dirty log synchronization when those two devices aren't used is introduced, but the overhead should be very small and acceptable. The benefit is cover future cases where those two devices are used without modifying the code.
