FYI, I have WIP patches to move the arm dma-iommu wrappers to common
code:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/dma-maybe-coherent
which will require some synchronization of the involved trees. In the
end it is iommu code, so the actual iommu patches should probably
go into the iommu tree after all, but it might have to pull in the
dma-mapping branch for that. Or we just punt it until the next merge
window. Not sure how fast Tom needs the common dma-iommu code for
the x86 AMD iommu conversion.
