arm is the last platform not using the dma-direct code for directly
mapped DMA.  With the dmaboune removal from Arnd we can easily switch
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.

Finally found some time to hook the machine up and throw a new kernel
at it. Booted at its usual glacial speed, so FWIW:

Tested-by: Marc Zyngier <maz@kernel.org>

Thanks,
