Looking for some feedback on this patch, MAINTAINERS points to Paul for
scsi stuff, and I saw Blue Swirl commit a scsi patch recently.
This patch fixes Linux machines configured with > 4G of ram and using a
SCSI device. I'm working on 64-bit DMA support as well which should
hopefully fix 64-bit Windows using SCSI devices as well.

Maybe the address could be calculated at script parsing phase for
small performance gain.
I would use ULL instead of UL, because on 32 bit host long is still 32 bits.
