Re: fully convert arm to use dma-direct

arm is the last platform not using the dma-direct code for directly

arm to always use dma-direct now (it already does for LPAE configs
and nommu).  I'd love to merge this series through the dma-mapping tree
as it gives us the opportunity for additional core dma-mapping
improvements.

I think Marc Z has a Netwinder that he can test this on. Marc?
I have one too, just not much in my office because of parental leave.
