But in this case it actually is the example to follow as told previously. NAK again for these chained dma ops that only create problems.Care to explain what should be done instead?
Override phys_to_dma and dma_to_phys as mips and x86 do for similar situations. Bonous points of finding some generic way of doing it instead of hiding it in arch code.
