Great, thanks. I'll apply the patches as soon as the relevant ACKs come
in. Looking at the MAINTAINERS file David Brown needs to ACK the MSM
patch and David Woodhouse the VT-d patch.

David B., David W., is this direction ok for both of you?

A more important question is how we handle the IOMMU tree. Currently the
situation is as follows:

* The AMD IOMMU changes go upstream through Ingo
* David Woohouse has his own tree which he sents directly to
Linus
* Not sure about the ARM IOMMU code
* And to comlicate things further there is the upcoming ARM
integration tree which may contain code that depends on IOMMU
changes

My suggestion is that the ARM tree pulls in the necessary changes from
the IOMMU tree and the IOMMU code goes upstream through Ingo or directly
to Linus (with some time in linux-next, of course). Thoughts?
