No, you're looking at this from the wrong angle. This is going to be
user-visible and the moment it gets upstream, it is cast in stone.
So the whole use case of what luserspace needs to do or is going to do
or wants to do on a SEGV_CPERR, needs to be described, agreed upon by
people etc before it goes out. And thus clarified whether the address

Thx.
