Create a dedicated iommu drivers folder, put the base iommu code there,
and move the existing IOMMU API users as well (msm-iommu, amd_iommu and
intel-iommu).

Putting all iommu drivers together will ease finding similarities
between different platforms, with the intention of solving problems once,
in a generic framework, which everyone can use.

OMAP's iommu will be moved too as soon as it's migrated.

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?

I can certainly pull from you trees you pull from elsewhere.

David could help keep things tidier by sending the Intel IOMMU bits 
to me as well.

In any case the tip:core/iommu tree is in linux-next so whatever you 
send me shows up there on the next day or so.

Thanks,

	Ingo
