This patch just makes the version number in ips.c and ips.h consistent. It
seems that this has been forgotten in a60768e2d43eb30a1adb8a119aeac35dc0d03ef6.
It also removes code duplication, each number is now only once in the code to
avoid similar errors in the future.

We were releasing the IRQ before removing the host, so commands could
still be coming in which would never be seen by the interrupt handler.

If an error occurred during initialisation, we would sometimes fail to
call scsi_host_put() and thus end up with a leaked scsi_host. It was
also possible to miss calling scsi_remove_host().

Since ncr53c8xx_attach() calls scsi_host_put(), make ncr53c8xx_release()
call scsi_host_put() too, for symmetry. Both callers already expect
it to put the host for them, so that works out nicely. While the zalon
driver does 'use' the host pointer afterwards, it only compares it for
equality and doesn't dereference it, so that's safe.
While I'm at it, get rid of pointless checks for NULL, use shost_priv()
and change ncr53c8xx_release to return void.

If kthread_run failed, we would fail to scan the host, and leak the
allocated async_scan_data. Since using a separate thread is just an
optimisation, do the scan synchronously if we fail to spawn a thread.

The current code prints:
scsi 13:0:4:0: scsi: Device offlined - not ready after error recovery

sg uses a scheme to reallocate a single contiguous array of all its
pointers for lookup and management. This didn't matter too much when sg
could only attach 256 nodes, but now the maximum has been bumped up to
32k we're starting to push the limits of the maximum allocatable
contiguous memory. The solution to this is to eliminate the static
array and do everything via idr, which this patch does.

* Remove IRQF_DISABLED, it is clearly wrong for this driver.
* Remove wasteful spin_lock_irqsave() in interrupt handler.
The lighter-weight spin_lock() is all that's needed.
* Annotate with FIXME where arcmsr_interrupt() is called
without any spinlock being acquired.
* Eliminate pointless cast from void pointer in arcmsr_do_interrupt()

Remove _interruptible, since receiving a signal while waiting on a
hardware condition will simply cause the driver to busy-wait.
Using msleep_interruptible() is rarely the right thing to do, when
waiting on a hardware condition to change.
Also, replace msleep with ssleep while doing this, where appropriate.

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.
