[SCSI] move ULD attachment into the prep function
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).

[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.

- Call pci_set_master() instead of poking at config space directly
- Move the latency setting into one function called for both narrow and
wide boards.
- Tidy up AdvInitGetConfig() a little.
- Delete a few unused prototypes and definitions.

[SCSI] advansys: Convert to ISA driver model
Register two isa_drivers, one for ISA and one for VLB, in order to
preserve detection order. When deleting advansys_detect, we lose the
last vestiges of the code that limited IO port scanning. This code
has been effectively disabled for many years anyway; I'll restore it
in a module_param later. We also lose the code that placed all ISA PnP
cards into WaitForKey state -- drivers shouldn't be doing this anyway.
The asc_host array goes away too. Also remove some IOADR and other
definitions, such as ASC_NUM_BOARD_SUPPORTED.

[SCSI] Fix async scanning double-add problems
Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.
- Since async_scan is a bit, we need to hold the host_lock while
modifying it to prevent races against other CPUs modifying the word
that bit is in. This is probably a theoretical race for the moment,
but other patches may change that.
- The async_scan bit means not only that this host is being scanned
asynchronously, but that all the devices attached to this host are not
yet added to sysfs. So we must ensure that this bit is always in sync.
I've chosen to do this with the scan_mutex since it's already acquired
in most of the right places.
- If the host changes state to deleted while we're in the middle of
a scan, we'll end up with some devices on the host's list which must
be deleted. Add a check to scsi_sysfs_add_devices() to ensure the
host is still running.
- To avoid the async_scan bit being protected by three locks, the
async_scan_lock now only protects the scanning_list.
