Since MSI-X vectors do not require a clearing "handshake" from
the system perspective, and the registered handler will not be
called more than once for one occurrence of receipt of a vector,
there is no requirement to flush the risc register write clearing
the interrupt condition in the risc. Also, since the msi-x
registered handlers are optimised for a particular vector, it is
preferable to handle the one vector received per invocation of
the handler.

One of the intents of the block prep function was to allow ULDs to use
it for preprocessing. The original SCSI model was to have a single prep
function and add a pointer indirect filter to build the necessary
commands. This patch reverses that, does away with the init_command
field of the scsi_driver structure and makes ULDs attach directly to the
prep function instead. The value is really that it allows us to begin
to separate the ULDs from the SCSI mid layer (as long as they don't use
any core functions---which is hard at the moment---a ULD doesn't even
need SCSI to bind).

In scsi module I've found some inconsistency between variable type
used in module_param_named and type passed to module_param_named as an
argument. Especially the inconsistency of `max_scsi_luns' parameter is
a bit serious because the description text says "last scsi LUN (should
be between 1 and 2^32-1)".

- Convert ide-scsi to the new data accessors and cleanup
the !use_sg code paths.
In old code the driver was trying to translate narrow commands,
if received, to wide commands. This code path still assumed
scsi_cmnd->request_buffer is a linear char pointer.
This means that this driver was broken since 2.6.17.
As suggested by Christoph Hellwig I set
use_10_for_rw = 1; and use_10_for_ms = 1;
for this device and completely killed the translation.

A BUSY status returned on a write request results in a stale residual
being returned when the write ultimately successfully completes.
This can be reproduced as follows:
1) issue immediate mode rewind to scsi tape drive
2) issue write request
The tape drive returns busy. The low level driver detects underrun and
sets the residual into the scsi command. The low level driver responds
with (DID_OK << 16) | scsi_status. scsi_status is 8, hence
status_byte(result) == 4, i.e., BUSY.
scsi_softirq_done() calls scsi_decide_disposition() which returns
ADD_TO_MLQUEUE. scsi_softirq_done() then calls scsi_queue_insert()
which, on the way to resubmitting the request to the driver, calls
scsi_init_cmd_errh().
The attached patch modifies scsi_init_cmd_errh() to clear the resid
field. This prevents a "stale" residual from being returned when the
scsi command finally completes without a BUSY status.

This removes the unused sysfs attribute overwriting logic for most of
the attributes, and plugs them into the driver core default attribute
creation.
Without this patch, at the time of the events for the SCSI LUN's, there
will be no sysfs files, because their creation is delayed until the sd
driver has spun up the disks, which might take several seconds. It is the
last WAIT_FOR_SYSFS rule in the default udev setup which can be removed
with this change.

- Replace ASC_ASSERT() with BUG_ON().
In a few places, get rid of the assertion altogether -- the ensuing
crash will tell us all we need to know. Use BUG() where it fits better
than BUG_ON(). Also fix a fencepost error in advansys_proc_info().
- Replace DvcSleepMilliSecond with mdelay.
Despite its name using 'sleep', the implementation was a delay.
I've marked some places with XXX where we should probably be using
msleep instead. They need to be audited to be sure we can sleep in
that context.
- Replace DvcDelayMicroSecond with udelay.
- Replace DvcDelayNanoSecond with udelay too.
All callers were multiples of 1000.
- Remove DvcEnterCritical and DvcLeaveCritical.
These functions are no-ops, and as the comments said, the spinlock
protects the critical sections.

The SCSI midlayer won't send commands greater than ->max_cmd_len.
So the checks on length in asc_build_req and adv_build_req are obsolete

The `active' list was used in the reset handler -- but the midlayer
guarantees that list is empty by the time the reset handler is invoked.
It was also checked in the interrupt routines to be sure that this command
belonged to this board, but we don't need to check that either. We can
then delete the asc_prt_target_stats() function as it will never print
anything, along with asc_enqueue(), asc_dequeue_list(), asc_rmqueue(),
asc_scsi_done_list(), struct asc_queue, ASC_QUEUE_EMPTY, ASC_TID_ALL,
ASC_FRONT, ASC_BACK, and all the REQ* macros. Also remove this item from

- Move the guts of asc_scsi_done_list() into a new function, asc_scsi_done.
- Call asc_scsi_done() in asc_isr_callback() and adv_isr_callback(). The
comment was wrong; scsi_done cannot enable interrupts.
- All other places which queued an scp on the done list are error paths
for queuecommand, and so we can just call asc_scsi_done() in queuecommand
if we receive an error.
- We no longer need to keep a list of done requests in advansys_interrupt
