Thanks for taking care of that. I'm going to need to add a non-Tegra configuration to my build scripts and make sure I run those. On a related note: have you ever considered submitting the Nouveau tree for linux-next? That'd be very convenient for people like me working on multiple patch series at the same time. In fact I've got another set of patches against Nouveau that I want to send out after you've merged these. Technically I would need to rebase them on your tree (since there may be dependencies on this set), but that means I need to pull in both your tree and linux-next if I want to keep up to date on all fronts and test all patches in my local tree at the same time. I'm not sure how well that would fit into your workflow. It's typically not more effort than setting up a permanent branch that you can push to whenever there's something that's ready for broader consumption. Beyond the initial setup (which is really not more complicated than sending Stephen an email with a URL and the branch name), it's really quite simple and goes a long way to get broad testing early on. And it's especially handy to catch potential conflicts with cross-subsystem changes like the IOMMU patches in this series.
