...and in that case, shouldn't it be using something like a union of an
integral type and a void *? I realize that this is the kernel, and a
certain amount of relaxation of the integral/pointer divide is to be
expected, but this is one of the last places I would expect it to show.
(I expect it in things like the pmap, or the VM subsystem. Not places
that just *use* pointers.)
