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!

+ *
+ * RETURN VALUES
+ * dasd_era_none no error
+ * dasd_era_fatal for all fatal (unrecoverable errors)
+ * dasd_era_recover for all others.
