From e257ad062a3ceaf36b0e883d0ef00b185daf500e Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 25 Jul 2007 11:18:00 +0900 Subject: sh: Kill off virt_to_bus()/bus_to_virt(). Wire up ARCH_NO_VIRT_TO_BUS, and kill off the remaining users. The dma-mapping code really wanted virt_to_phys()/phys_to_virt() anyways, there are no inherently special bus addresses.
