Re: [PATCH RFC 2/5] ARM: introduce arm_dma_direct

I think we just need to byte the bullet and move over arm to dma-direct
entirely. This needs a careful audit of what differs, but the biggest
item is that we need to ensure dmabounce keeps working (or is replaced
with swiotlb in a suitable way, but that might be a lot more work).
