This patch changes the way we complete commands. In the old method when we
got a completion we searched our command list from the top until we find it.
This method uses a tag associated with each command (not SCSI command tagging)
to index us directly to the completed command. This helps performance.

This patch removes a couple of functions dealing with configuration and
replaces them with new functions. This implementation fixes some bugs
associated with the ACUXE. It also allows a logical volume to be removed from
the middle without deleting all volumes behind it.
If a user has 5 logical volumes and decides he wants to reconfigure volume
number 3, he can now do that without removing volumes 4 & 5 first. This code
has been tested in our labs against all application software.

This patch adds a flag called busy_initializing. If there are multiple
controllers in a server AND the HP agents are running it's possible the agents
may try to poll a card that is still initializing if the driver is removed and
then added again.

This patch adds per disk queue functionality to cciss. Sometime back I
submitted a patch but it looks like only part of what I needed. In the 2.6
kernel if we have more than one logical volume the driver will Oops during
rmmod. It seems all of the queues actually point back to the same queue.
So after deleting the first volume you hit a null pointer on the second
one.
This has been tested in our labs. There is no difference in performance,
it just fixes the Oops.

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!
