Sebastian Ott 6b7df3ce92 s390/pci: fix dma address calculation in map_sg ... __s390_dma_map_sg maps a dma-contiguous area. Although we only map whole pages we have to take into account that the area doesn't start or stop at a page boundary because we use the dma address to loop over the individual sg entries. Failing to do that might lead to an access of the wrong sg entry.
