*	powerpc: Fix DMA offset for non-coherent DMA	Benjamin Herrenschmidt	2008-10-14	1	-2/+6
\| \| \| \| \| \| \| \| \| \|	After Becky's work we can almost have different DMA offsets between on-chip devices and PCI. Almost because there's a problem with the non-coherent DMA code that basically ignores the programmed offset to use the global one for everything. This fixes it.

*	powerpc: Merge 32 and 64-bit dma code	Becky Bruce	2008-09-24	1	-23/+46
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	powerpc: Drop archdata numa_node	Becky Bruce	2008-09-24	1	-1/+1
\| \| \| \| \| \| \| \|	Use the struct device's numa_node instead; use accessor functions to get/set numa_node. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
*	powerpc: Move iommu dma ops from dma.c to dma-iommu.c	Becky Bruce	2008-09-24	1	-97/+1
\| \| \| \| \| \| \| \|	32-bit platforms are about to start using dma.c; move the iommu dma ops into their own file to make this a bit cleaner. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
*	powerpc: Rename dma_64.c to dma.c	Becky Bruce	2008-09-24	1	-0/+200
	This is in preparation for the merge of the 32 and 64-bit dma code in arch/powerpc. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
