This is giving

In file included from drivers/scsi/BusLogic.c:57:0:
drivers/scsi/FlashPoint.c: In function ‘FPT_busMstrDataXferStart’:
drivers/scsi/FlashPoint.c:5050:10: warning: cast from pointer to integer
of different size [-Wpointer-to-int-cast]

to do this cast, you need first to cast to unsigned long and then
truncate the long with u32.  I fixed it up.
