I've sorted that out separately -- it's not necessarily part of this
fix, although it _would_ be nice to have it in 2.6.31, since your
original 1:1 mapping patch is quite slow (and takes quite a lot of
memory) without it.
This time, I _am_ going to let it bake in linux-next for a while first
though.
Until Linus pulls the IA64 build fix from the real iommu-2.6.git tree,
I've put this into git://git.infradead.org/~dwmw2/iommu-pt.git
