I've had a go at getting the DMA AIO working. It compiles, but I don't
have access to the hardware, so I have done no more testing than that.
The fifth patch removes the cancel call-back because it is empty and so
doesn't serve any purpose (AFAICS). However, it doesn't appear to be
too tricky to implement something that would abort the transfer in the
same manner that kpc_dma_close() if this would be useful.
