This is the purpose that linux-next serves, not the x86 forest-of-doom.

And I thought Ingo said his old iommu tree wasn't in there anyway? He
said it was somewhere else, although I haven't actually managed to
_find_ it.

The Intel IOMMU appears on IA64 too, and doesn't want to be developed
and tested off in an x86-specific corner by itself. And I'm going to be
looking at other generic things we can do to improve IOMMU-related
performance, which will touch on other architectures too.
