I've recently moved the original series into mm.git's mm-new branch, which
isn't included in linux-next.  Because it appeared that the v2 series
wouldn't be available in time for the next merge window.

It is a wonderful performance improvement, but I think it's best that
we revisit the series for the next -rc cycle.  So can you please
integrate this new change into "ksm: optimize rmap_walk_ksm by passing
a suitable addressrange", rework the changelogs to reflect the
discussion thus far and resend the "KSM: Optimizations for
rmap_walk_ksm" series?
