this patchset introduces code to debug drivers usage of the DMA-API.
Tests with hardware IOMMUs have shown several bugs in drivers
regarding the usage of that API.
Problems were found especially in network card drivers.

This is really useful -- but surely it shouldn't be x86-specific?

All the code except the hooks in the architecture's dma_map_single() et
al functions could be generic, couldn't it?
