Someone was just mentioning in another thread that removing the check
from iounmap() is not portable to other arches and then I remembered
that Markus removed a bunch of these.

We should consider reverting this, perhaps?

Can't we teach all architectures? Not that reverting it would be a
problem.

We probably should.  I just didn't want to suggest it, in case it sounds
like volunteering...  I'm not going to be able to do it because I'm on
the road for a bit.
