Use block shared tags entirely within the driver. In the case of
shutdown, assume that there are no other outstanding commands, so tag
0 is fine.

Add Promise SuperTrak 'stex' driver, supporting SuperTrak
EX8350/8300/16350/16300 controllers. The controller's firmware accepts
SCSI commands, handing them to the underlying RAID or JBOD disks.
The driver consisted of the following cleanups and fixes, beyond its
initial submission:
Ed Lin:
stex: cleanup and minor fixes
stex: add new device ids
stex: update internal copy code path
stex: add hard reset function
stex: adjust command timeout in slave_config routine
stex: use more efficient method for unload/shutdown flush
Jeff Garzik:
[SCSI] Add Promise SuperTrak 'shasta' driver.
Rename drivers/scsi/shasta.c to stex.c ("SuperTrak EX").
[SCSI] stex: update with community comments from 'Promise SuperTrak' thread
[SCSI] stex: Fix warning, trim trailing whitespace.
[SCSI] stex: remove last remnants of "shasta" project code name
[SCSI] stex: removed 6-byte command emulation
[SCSI] stex: minor cleanups
[SCSI] stex: minor fixes: irq flag, error return value
[SCSI] stex: use dma_alloc_coherent()
