Ok, that can't work, since the ring_pages[] allocation happens later.
So that part needs to be moved up, and it needs to initialize
'nr_pages'.

So here's the same patch, but with stuff moved around a bit, and the
"oops, couldn't create page" part fixed.

Bit it's still totally and entirely untested.
