From a17b4904206eda7d1120a099a9717e73113b275d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 9 May 2007 09:15:27 +0200 Subject: [PATCH] i386 dma_map_sg: convert to using sg helpers The dma mapping helpers need to be converted to using sg helpers as well, so they will work with a chained sglist setup.
