Currently, the maximum amount of RAM that scsi_debug can allocate is
4GB. This patch increases it to 2TB; scsi_debug can allocates 2TB
memory and export it as if it were 2TB scsi disk.

Tomo,
Unsigned long is 32 bits on i386 (and 64 bits in the LP64
data model). Don't you want 64 bits in all cases? Either
unsigned long long, uint64_t or one of those crappy
kernel typedefs for 64 bits.
BTW I recently removed just about all the "unsigned long"
declarations out of sg3_utils due the uncertainty about the
size of "long".
