I'm not sure what the issue at hand is, but: the SCSI/RAID pass through
interfaces that I had involvement with allow I/O directly to disks. Also
since we can't trust either the firmware or the user-space consumers, we
can't rule out the possibility that the interfaces could be used to access
physical memory.
