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!

+ * Description:   Driver for the Toshiba OBOE (or type-O or 701)
+ *                FIR Chipset, also supports the DONAUOBOE (type-DO

+ *                register compatible.
+ * Status:        Experimental.
