I agree. We would not start mapping a userspace address at VA 0 again, to stop
dereferences of NULL pointers to core, right?

This does not mean that we should remove the "(null)" output from printf,
and maybe add it to puts as a stopgap fix.

But IMHO we should discourage passing NULL pointers as %s to *printf* in the
style doc and fix callers as we discover them.
