As far as the consolidation patch goes, lack of testing was the main
objective reason for holding back.  So if you could test on x86_64 and
ia64 too, that would be great.  wli had some objections to the patch
when I first posted which I didn't and don't really understand, and
from conversations with akpm, I'm certainly thinking of just
re-sending it.

COW will be a bit more of a political shitfight, I suspect.  I'd like
to at least hold off until the consolidation is merged, which makes
the COW much easier.  We'll also need to implement the necessary
arch-hooks for COW on every platform.  Speaking of which, did you
implement the i386 hooks?  I thought I only did COW for ppc64, so far,
although on top of the consolidation patch the amount of arch code is
vastly reduced.
