The following patch fixes a crash caused by attempting to bounce buffer
when an IDE CD-ROM is used on a machine with an IO-MMU. [At least, this
patch fixes things so I can use my IDE CD-ROM behind an ns87415 on a 
HP PA-RISC workstation.]

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!
