The following patch fixes a bug in the SGI Altix sn_dma_flush code.
sn_dma_flush is broken in 2.6. The code isn't waiting for the DMA
data to be flushed out of the PIC ASIC. This patch is based off the
linux-ia64-test-2.6.12 tree

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!
