Hartmut Brandt e557905435 Fix a problem in bus_dmamap_load_{mbuf,uio} when the first mbuf or the first ... uio segment is empty. In this case no dma segment is create by bus_dmamap_load_buffer, but the calling routine clears the first flag. Under certain combinations of addresses of the first and second mbuf/uio buffer this leads to corrupted DMA segment descriptors. This was already fixed by tmm in sparc64/sparc64/iommu.c.
