From 4b1c5df2af38b2681b7c1a058534d17c54aaf6cf Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 27 Aug 2008 18:40:38 -0700 Subject: sparc32: Make mmu_map_dma_area and mmu_unmap_dma_area take a device pointer. This lets us kill this "map it in every IOMMU" crazy code, and also some of the final references to sbus_root. Signed-off-by: David S.
