-Subject: [PATCH] virtio: add check for descriptor's mapped address
-
-virtio back end uses set of buffers to facilitate I/O operations.
-If its size is too large, 'cpu_physical_memory_map' could return
-a null address. This would result in a null dereference while
-un-mapping descriptors. Add check to avoid it.
