Architecture maintainers are not supposed to decide whether driver writers understand APIs. The dma64_addr_t type is part of the PCI DMA interface and IA64 needs to defines it. You do have a point, but so does David. What driver wants to get at this type and what are they using it for? dma_addr_t should be used by every driver I am aware of except the clustering PCI cards I've been told about and that driver isn't in the kernel at this time. So who needs it? :-)
