impact to arch/ia64 might be minimal. My understanding was all the drivers that support 32-bit devices would need tweaks to use GFP_DMA32 flag. Is this still the plan? http://www.ussg.iu.edu/hypermail/linux/kernel/9901.3/0323.html
Most of what I've read in Andi's patch otherwise makes sense: http://lwn.net/Articles/152337/
But I didn't see Andi suggest that swiotlb should go completely away.
