If it is a 'a bit' then sure, but I suspect doing a good job here will be a lot of code here. Look at how big scatterlist is, for instance. Maybe we could have a generic 64 bit interval arry and then two type wrappers that do dma and physaddr casting? IDK. Not sure type safety of DMA vs CPU address is critical? Jason
