[PATCH] powerpc: Move dart.h
asm-ppc64/dart.h is included in exactly one place - arch/powerpc/sysdev/u3_iommu.c. This patch, therefore, moves it into arch/powerpc/sysdev. While we're at it, update the #ifndef/#define protecting the include, and the filename in the comments of u3_iommu.c. Built and booted on pSeries and G5, built for ppc32 powermac. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
