And ? Who cares ? Drivers who know about a 32-bit limitations use
GFP_DMA32, that's what is expected, don't mess around with ZONE_DMA.

I thought drivers are supposed to set a dma_mask, and
dma_alloc_coherent() is supposed to use that to figure out how to
honor that mask.

Sure, that's the right way to go, I meant bits of pieces of the
infrastructure in between. Why diverge from other archs gratuituously
here ?
