(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls that are used by the dma_ops routines. This is the approach of arch/mips/cavium-octeon/dma-octeon.cMIPS is rarely an example to follow. :)
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.
