This series is for adding virtio-gpu driver the support for the suspend and resume (or freeze and restore).
First patch adds virtio-dev hooks that adds .freeze and .restore hooks that basically flush and remove virtqueue before going into suspension then reinitialize them upon wake-up event. Second patch is the implementation of virtio-gpu resource restoration machanism that is needed for the synchronization of resources between the host and the guest when suspend(and hibernation) and resume happens.
