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

[SCSI] ide-scsi.: convert to data accessors and !use_sg cleanup
- 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.
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.

[SCSI] mpt fusion: Add support for ATTO 4LD: Rebranded LSI 53C1030
Per request from Matthew Wilcox - using PCI_VENDOR_ATTO.
Add support for ATTO UL4D, they are rebranded 53C1030.
The changes are
1. Adding a new PCI vendor ID in pci table
2. The spi_port_page_2 is in different format than that of LSI generic
spi_port_page_2 and hence mapping code is added.
