iommu_map() calls trace_map() with iova and size. trace_map() should report original iova and original size as opposed to iova and size after they get changed during mapping. size is always zero at the end of mapping which is useless to report and iova as it gets incremented, it is not as useful as the original iova. Change iommu_map() to call trace_map() to report original iova and original size.
