[SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-only

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden  raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume.  In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

[SCSI] a100u2w: Convert into Linux style

I was investigating strange driver behaviour and thought that readable
code and proper visible types might help explain why it didn't work right
the moment a second SCB was outstanding to the controller. I was right

- Cleanup, linuxise, demacro
- Remove the BSD dual licence on the new work
- Switch the if ALPHA to if __LP64__. (struct size is then right
elsewhere) and then to CONFIG_64BIT as per Christoph's request
- Fix the recursive locking on a reset. This is the only actual real code
change (I hope ;)).

I'm not clear what the right way to handle the BIOS param stuff is on n
on x86-32/64. Using phys_to_virt and stuff is ugly and probably doesn't
make sense elsewhere

Still has a couple of odd things - and there seems to be a commonly shared
EEPROM handling error several drivers have. Roughly speaking several SCSI
drivers go

try and read EEPROM
It failed..
Write any changes between the default and the data we read

Which is great as for some paths we've no idea what was in
before, so each boot won't write it all back, won't checksum but will
repeat the bug

Also it can still sleep for a second with IRQ off, and there is some
dubious looking error path locking marked FIXME in case anyone feels
inspired to work on it. Not a newly introduced bug, and at least its now

[SCSI] iscsi_tcp: fix handling of data buffer padding

If we got the padding, data and header in different skbs,
we were not handling the padding correctly because we attributed it
to the data's skb. This resulted in the initiator reading from
pad bytes + skb offset instead of the correct offset.

If you could not connect with the open solaris target, this
will fix the lock up problem you were hitting.

The cmdsn allocation and pdu transmit code can race, and we can end
up sending a pdu with cmdsn 10 before a pdu with 5. The target will
then fail the connection/session. This patch fixes the problem by
delaying the cmdsn allocation until we are about to send the pdu.

This also removes the xmitmutex. We were using the connection xmitmutex
during error handling to handle races with mtask and ctask cleanup and
completion. For ctasks we now have nice refcounting and for the mtask,
if we hit the case where the mtask timesout and it is floating
around somewhere in the driver, we end up dropping the session.
And to handle session level cleanup, we use the xmit suspend bit
along with scsi_flush_queue and the session lock to make sure
