"out of pci_dev" and into struct device? I think that's all parisc port would need now.
At some point I'd like to propose "dma_hint" field. But I don't have a specific proposal yet. Something to help drivers communicate DMA characteristics to the IOMMU support code. ie bandwidth needed, cacheline line aware, MWLI support, etc.
