Please, please do the function moves in a different patch. Or use a
simple prototype declaration like I did to avoid moving the code around
in the first place.

I think you're done allocating things by the time this is called. But to
be sure you can call _base_config_dma_addressing() after you're done
with the RDPQ allocations (or rearrange the code so you allocate RDPQ
before the DMA mask is upped in general).
