All driver should be using dma_set_mask / pci_set_dma_mask to try to set the dma mask instead of just querying it. Without that some iommu implementations may not work.
pci_dma_supported is removed entirely, but dma_supported stays for dma_ops implementations for now. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
