From: Greg Ungerer <gerg@xxxxxxxxxxx> On all ColdFire platforms (whether MMU enabled or not) we want to use the simple page based dma_alloc_coherent. We don't want the virtual mapping version that is used on classic m68k setups. So modify the conditionals to use the existing simpler dma_alloc_coherent on all ColdFire and non-MMU builds.
