So that isn't quite the same. Before we only set m.severity for
memory errors where we had a valid address. Now you unconditionally
set it.

Maybe that's more useful. But it now needs an audit of the code
the registered notifiers to make sure they didn't assume that
severity set meant that this is a memory error.
