This patchset transforms the PCI DMA API into the generic device model. It's one of the reasons why we introduced the generic DMA API long ago; driver writers are always able to use the generic DMA API with any bus instead of using bus specific DMA APIs such as pci_map_single, sbus_map_single, etc (only two bus specific APIs exist now; pci and ssb).
Some of the PCI DMA API are already implented on the top of the generic DMA API (include/asm-generic/pci-dma-compat.h). But there are some exceptions. This patchset finishes the transformation.
