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).
