One of the programming techniques for modules is you must explicitly

all objects subject to DMA such that they are known to be physically
contiguous
if necessary.
I should have also mentioned that using these functions also returns
both physical and virtual addresses that you should keep within your
driver so you can avoid calling any function/macro that converts
between physical and virtual addresses.
