New code from the Adaptec driver.  Performance enhancement for newer
adapters.  I hope that this isn't too big for a single patch.  I believe
that other than the few small cleanups mentioned, that the changes are
all related.

- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
  requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup

Passes sparse check.
I have tested it on x86 and ppc64 machines.

return the result of the TEST UNIT READY or the start/stop commands. Code
is already in place to save and restore the result for the request sense

scsi_queue_insert() has four callers.  Three callers call with
timer disabled and one (the second invocation in
scsi_dispatch_cmd()) calls with timer activated.
scsi_queue_insert() used to always call scsi_delete_timer()
and ignore the return value.  This results in race with timer
expiration.  Remove scsi_delete_timer() call from
scsi_queue_insert() and make the caller delete timer and check
the return value.

Currently, during PCI hotplug remove, if the upper layer

This patch addresses the sparse -Wbitwise warnings that Christoph wanted

elements of hardware associated structures the __le* equivalent.

machine running bonnie++.  The usage of the LE32_ALL_ONES macro has been

scsi_queue_insert() used to use blk_insert_request() for requeueing
requests.  This depends on the unobvious behavior of
blk_insert_request() setting REQ_SPECIAL and REQ_SOFTBARRIER when
requeueing.  This patch makes scsi_queue_insert() use
blk_requeue_request().  As REQ_SPECIAL means special requests and
REQ_SOFTBARRIER is automatically handled by blk layer now, no flag
needs to be set.

Note that scsi_queue_insert() now calls scsi_run_queue() itself, and
the prototype of the function is added right above
scsi_queue_insert().  This is temporary, as later requeue path
consolidation patchset removes scsi_queue_insert().  By adding
temporary prototype, we can do away with unnecessarily moving
functions.
