------------------------------------------------------
Subject: sparc32: add offset in pci_map_sg()
From: Jan Andersson jan.andersson@xxxxxxxx
Add sg->offset to sg->dvma_address in pci_map_sg() on sparc32. Without the
offset, transfers to buffers that do not begin on a page boundary will not
work as expected.
