Amusingly, after having updated my system to Avi's tree, I find
I don't need the unassigned_mem_read[bwl] helpers anymore, but
only the cpu_unassigned_access function, which is already exported.
It would be nice if the new api allowed signaling of errors, but
I can't think of a really nice way of doing that.
