From f6ae31c23be6926359e9379acfdbbdd945209f05 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 26 May 2010 14:44:43 -0700 Subject: [PATCH] parisc: use asm-generic/scatterlist.h parisc uses iova and iova_length in scatterlist structure instead of dma_address and dma_length. However, the accessor are used so we can convert parisc to use asm-generic/scatterlist.h easily. Signed-off-by: FUJITA Tomonori Cc: Kyle McMartin Cc: Helge Deller Cc: James E.J.
