Other architectures seem to call their unwind_next() unwind_next_frame()
instead, and use a function unwind_done() rather than unwind_continue().
I appreciate that's actually a change carried through from one of the
earlier patches but might be worth considering. I don't really *mind*
that, though if there's any work on pulling more code out of the
architecture into the generic code it'll need revisiting in at least
some of the architectures.
