[PATCH] scsi: remove volatile from scsi data

This patch removes volatile qualifier from scsi_device->device_busy,
Scsi_Host->host_busy and ->host_failed as the volatile qualifiers
don't serve any purpose now. While at it, convert those fields from
unsigned short to unsigned int as suggested by Christoph.

updates for CFQ oops fix

- add a comment to the device structure that the device_busy field
is now protected by the request_queue->queue_lock
- null out sdev->request_queue after the queue is released to trap
any (and there shouldn't be any) use after the queue is freed.

[PATCH] fix NMI lockup with CFQ scheduler

The current problem seen is that the queue lock is actually in the
SCSI device structure, so when that structure is freed on device
release, we go boom if the queue tries to access the lock again.

The fix here is to move the lock from the scsi_device to the queue.

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!
