In an FL topology, limit port recognition to those devices
not within the same area and domain of the ISP. The
firmware will recogonize such devices during local-loop
discovery.
Some devices may respond to a PLOGI before they have
completed their fabric login or they may not be a public
device. In this case they will report:
domain == 00
area == 00
alpa == <XX>
which is valid. Exclude such devices from local loop
discovery.

In order to efficiently utilise the ISP's IOCB
request-queue, use the dma_get_required_mask() function to
determine the use of command-type 2 or 3 IOCBs when queueing
SCSI commands. This applies to ISP2[123]xx chips only, as
the ISP24xx uses command-type 7 IOCBs which use 64bit DSDs.

This patch adopts the same solution as proposed by Kai M. in
a post titled: "[PATCH] SCSI tape signed/unsigned fix".
The fix is in a function that the sg driver borrowed from
the st driver so its maintenance is a little easier if
the functions remain the same after the fix.

from get_user_pages() call are properly handled
