2008-09-24powerpc: Merge 32 and 64-bit dma codeBecky Bruce
We essentially adopt the 64-bit dma code, with some changes to support 32-bit systems, including HIGHMEM. dma functions on 32-bit are now invoked via accessor functions which call the correct op for a device based on archdata dma_ops. If there is no archdata dma_ops, this defaults to dma_direct_ops. In addition, the dma_map/unmap_page functions are added to dma_ops because we can't just fall back on map/unmap_single when HIGHMEM is enabled. In the case of dma_direct_*, we stop using map/unmap_single and just use the page version - this saves a lot of ugly ifdeffing. We leave map/unmap_single in the dma_ops definition, though, because they are needed by the iommu code, which does not implement map/unmap_page. Ideally, going forward, we will completely eliminate map/unmap_single and just have map/unmap_page, if it's workable for 64-bit.

2008-08-04powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
