At the moment we don't properly check the GITS_BASER<n>.Valid bit before saving the collection and device tables. On vgic_its_save_collection_table() we use the GITS_BASER gpa field whereas the Valid bit should be used. On vgic_its_save_device_tables() there is no check. This can cause various bugs, among which a subsequent fault when accessing the table in guest memory. Let's systematically check the Valid bit before doing anything. We also uniformize the code between save and restore.
