The patches implement .iotlb_sync() so that it is okay to not have a
.iotlb_range_add() call-back for now. But the patches lack a
.flush_iotlb_range() call-back, which is strictly necessary for
correctness because it is defined to be synchronous and doesn't require
a sync-call afterwards.
Regards,
Joerg
