No, Im failing to see his point which appears to be that if we modify the DMA API it has to work on all platforms, even if it doesnt work on them currently.

How? I havent proposed any alteration to the API, just the allocation system inside it. No drivers would need modification and any platform not using these allocators would continue to not use them just as it currently does(nt).

Except that the OHCI driver (for example) doesnt. it uses the DMA API (quite rightly) and to use ioremap would mean creating two ohci drivers, one using the DMA API and one not, which is wasteful and asking for trouble.
