In order to support user tools accessing the array components (SMART,
Mode Page information, Cache page adjustments, WWN determination,
Firmware updates etc), we take advantage of the no_uld_attach flag and
deprecate the code that filters Inquiries to block the requests to array
components. The quirk prevents the sd layer from attaching to the
components.

We also took the opportunity to balance the queue depths based on the
total adapter queue depth to the array devices to reduce the chances of
starvation.

Juan was kind enough to linger on site, and work on a production
machine, to try the parameter to make the system stable. He discovered
that reducing the maximum transfer size issued to the adapter to 128KB
stabilized his system. This is related to an earlier change for the
2.6.13 tree resulting from Martin Drab's testing where the transfer size
was reduced from 4G to 256KB; we needed to go still further in scaling
back the request size.

Here is the patch that tames this regression.

High Priority Queues have *never* been used in the entire history of the
aac based adapters. Associated with this, aac_insert_entry can be
removed, SavedIrql can be removed & padding variable can be removed.
With the movement of SavedIrql out & replaced with an automatic variable
qflags, the locking can be refined somewhat. The sparse warnings did not
catch the need for byte swapping in the 'dprintk' debugging print
macros, so fixed this up when this code was moved outside of the now
refined locking.

The size of the command packet's scatter gather list maximum size was
miscalculated in the low range leading to the driver initialization
limiting the maximum i/o size that could go to the Adapter. There were
no negative operational side effects resulting from this bad math, only
a subtle limit in performance of the Adapter at the top end of the
range.

In the rare instances where the adapter, or the motherboard, is
misbehaving; driver initialization or shutdown becomes problematic. By
introducing a 3 minute timeout on the first interrupt driven command
during initialization, or the issuance of the adapter shutdown command
during driver unload, we can resolve the lockup problems induced by
common (but rare) hardware misbehaviors.

The timeout during initialization, should it occur, is accompanied by a
message presented to the console and the logs indicating that the user
should inspect and resolve problems with interrupt routing.

The cmd->timeout field has been obsolete for a while now.  While looking
to remove it, I came across this use in the aacraid driver.  It looks
like you want to initialise the firmware with the current timeout of the
command (in seconds), so the value I think you should be using is
cmd->timeout_per_command.

If the Adapter is quiet and does not produce an AIF event packets to be
picked up by the management applications for longer than the timeout
interval of two minutes, the cleanup code that deals with aging out
registrants could erroneously drop the registration. The timeout is
there to clean up should the management application die and fail to poll
for updated AIF event packets.

Moving the timer update from the ioctl code that delivers an AIF to the
polling registrant to the bottom of the ioctl means the timeout is reset
with any management application polling activity regardless if an AIF is
delivered or not removing the erroneous timeout cleanups.
