Just a thought.

Would it be worth adding some comments to the code to explain why this
is needed, reading
the thread around my original patches and the DMA-API documentation it
is not instantly
clear why you would be mapping the pages in this way.

Would probably prevent someone in the future making the same mistake I
did while updating
this code.
