From aa83a26a193bf06ac6c822ccd881c62898a351c6 Mon Sep 17 00:00:00 2001 From: Robert Reif Date: Thu, 11 Dec 2008 20:24:58 -0800 Subject: [PATCH] sparc: use sparc64 version of scatterlist.h Use sparc64 version of scatterlist.h. There are three main differences: dma_addr_t replaces __u32 dma_address replaces dvma_address dma_length replaces dvma_length dma_addr_t is a u32 on sparc32. Boot tested on sparc32.
