...

Fix up trivial conflicts in arch/microblaze/kernel/Makefile due to just
some obj-y removals by the devicetree branch, while the microblaze
updates added a new file.

And stick the iommu archdata pointer into the generic OF device tree

We still have to pass the sbus_bus object down into the routines so
that the SBUS bus objects get the iommu cookies set properly. After
drivers get converted to being pure OF drivers, that can go away.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
