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).

used in module_param_named and type passed to module_param_named as an

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.
