From 7cdad482974792419cfe4b0affca689170116f49 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 4 Jan 2006 15:08:30 +0000 Subject: [ARM] Remove '__address' from scatterlist and convert to DMA API The old __address element in struct scatterlist remained from older kernels because the ARM DMA emulation code made use of it. Move this field into struct dma_struct, and convert DMA emulation code to setup a SG entry as required. Also, convert DMA emulation code to use the new DMA API rather than the PCI DMA API.
