Subject[GIT] Sparc

The PowerPC folks have a really nice scalable IOMMU pool allocator
that we wanted to make use of for sparc. So here we have a series
that abstracts out their code into a common layer that anyone can
make use of.

Sparc is converted, and the PowerPC folks have reviewed and ACK'd
this series and plan to convert PowerPC over as well.

Please pull, thanks a lot!
