To speed up the memory mapping updating between vhost-vDPA and vDPA device driver, this patch passes the IOTLB batching flags via IOTLB API. Two new flags was introduced, VHOST_IOTLB_BATCH_BEGIN is a hint that a bathced IOTLB updating may be initiated from the userspace. VHOST_IOTLB_BATCH_END is a hint that userspace has finished the updating: VHOST_IOTLB_BATCH_BEGIN VHOST_IOTLB_UPDATE/VHOST_IOTLB_INVALIDATE ... VHOST_IOTLB_BATCH_END Vhost-vDPA can then know that all mappings has been set and can do optimization like passing all the mappings to the vDPA device driver.
