yeah, GART/IOMMU has been historically a more platform specific thing
although there's certainly no hard boundaries. This code will show up in
linux-next as well soon, so there's plenty of time to discover and fix
any cross-arch breakages. (if any)
and if the PCI tree becomes very active in this area that would make the
movement of these commits over there more practical we can do that too
at any point of time, it's all kept separate in tip/x86/iommu, purely
based on Linus's tree. The blessings of 160+ topic branches ;-)
