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!

+ FlashPoint.c -- FlashPoint SCCB Manager for Linux
+
+ This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
+ Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
+ Linux compatibility. It was provided by BusLogic in the form of 16 separate
+ source files, which would have unnecessarily cluttered the scsi directory, so
+ the individual files have been combined into this single file.
