Thanks, Well, we can't hold up things forever. Given that the POWER guys had long discussions with you about previous versions but not about this one counts as a silent Ack for me ;) So I already applied the patches into my local tree yesterday and gave them some additional testing. All looks good so far. I think I will push the result soon to get this into linux-next. I'll probably rebase to add the Cc's to the commits before pushing it out.

Great, thanks Joerg! The IOMMU Groups code depends on changes in the PCI code. We need to work out how to merge this. Bjorn, I need the PCI changes before I can merge the IOMMU Groups code. There are two ways that would work for me: a) You Ack the PCI patch-set from Alex and I put it into my tree and merge the IOMMU Group code on-top, or b) You merge the PCI related patch-set into a seperate branch which you can merge into your next-branch and which I can pull in to merge IOMMU Groups on-top. Please let me know what works best for you. I also poked Bjorn with a minor v3 spin on his series, no change to this series. What I would also appreciate are a few more Acks from other IOMMU maintainers (David W.?) and from the Power side. Alexey, BenH, can either of you comment on this series from the POWER side? I know Alexey has an implementation of VFIO/Qemu device assignment working on POWER with this series. David Woodhouse, any comments?

My feeble excuse is that I was on vacation last week, but that's pretty lame because this has been hanging for much longer than that.
