From dbc1333a347745bd55844649c19eb7d28f383a84 Mon Sep 17 00:00:00 2001 From: Jan Andersson Date: Fri, 29 Dec 2006 16:50:04 -0800 Subject: [PATCH] [PATCH] sparc32: add offset in pci_map_sg() 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. Signed-off-by: Jan Andersson Cc: "David S.
