I was going to replace more instances of __pa(MAX_DMA_ADDRESS) with

noticed instances of virt_to_phys(MAX_DMA_ADDRESS) as well.  Can
someone tell me what the differences are between __pa() and virt_to_phys().
I noticed that on some archs they are the same, but are different on
others.

On which arches do they differ?
