This keeps coming up on linux-scsi; basically these are ioctls that
are called by some binary-only (and x86-binary-only at that) management
program.  so if they want to ship an ia64 version of their management
program, they'll have to fix this; otherwise the addresses are guaranteed
to be in the lower 32 bits of the address space.
