Linux-2.6.12-rc2v2.6.12-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!

+	 * all.
+	 * After some time of no movement, qdio_kick_outbound_q will
+	 * finally fail and reflect corresponding error codes to call
+	 * the upper layer module and have it take the queues down.
