How is your mach dma-direct.h scheme going to work, given that
we already have non-inline declarations of __phys_to_dma / __dma_to_phys
in this file?

Also this really should go into a separate commit, and we should either
have all of these functions inline or none. Having all of them out
of line seemed a lot saner to me to avoid all the mach header mess.

Also there seem to be a lot of randomw whitespace / brace cleanups
in this patch. Shouldn't those be split out as well?
