Re the Subject: change how? Perhaps "handle foreign mapped pages on the

Ok, I'll do that.


RX path need to know if the SKB fragments are stored on pages from another
domain.
Does this not need to be done either before the mapping change or at the
same time? -- otherwise you have a window of a couple of commits where
things are broken, breaking bisectability.
I can move this to the beginning, to keep bisectability. I've put it here originally because none of these makes sense without the previous patches.
