Apparently aiming for 3.16 right now.

Quite frankly, I don't think it's a Xen-only issue. The code was hard
to figure out even without the Xen issues. For example, nobody ever
explained to me why it

(a) could be the same as PROTNONE on x86
(b) could not be the same as PROTNONE in general

I think the best explanation for it so far was from the little voices
in my head that sang "It's a kind of Magic", and that isn't even
remotely the best song by Queen.
