Can we simple get rid of the stats or make then configurable (off by
defaut)? I agree they are rarely used and have been rarely used in the past.

Maybe some instrumentation for perf etc will allow
similar statistics these days? Thus its possible to drop them?

The space in the pcp pageset is precious and we should strive to use no
more than a cacheline for the diffs.
