I don't like silent fixups.  If we want to do this, we should BUG or
at least WARN, not just change the addr limit.  But I'm also not
convinced it's indicative of an actual bug here.

Nothing should enter that function with KERNEL_DS set, right?

It might very well do.  Various drivers or the networking code mess
with the address limits for fairly broad sections of code.
