I also ran mmtest configs/config-global-dhp__pagealloc-performance
config with changes including this series. (ie, the changes tested
include two patch series, one which change the pte format and this
series). I am attaching the results below. I removed the pagealloc
performance numbers from that because it was giving me all 00 which I
assume is due to systemtap script issue.
We don't see any performance impact with the series and some of the
performance change is withing the variance of test run as indicated by
the numbers below. We do find less page fault and in some case better
autonuma numbers
