I have yet to process all your mails, but assuming I address all
your review feedback and the latest unified tree in tip:master
shows no regression in your testing, would you be willing to
start using it for ongoing work?
It would make it much easier for me to pick up your
enhancements, fixes, etc.

To *really* see migration scalability bottlenecks you need to
remove the migration-bandwidth throttling kludge from your tree
(or configure it up very high if you want to do it simple).
Some (certainly not all) of the performance regressions you
reported were certainly due to numa/core code hitting the
migration codepaths as aggressively as the workload demanded -
and hitting scalability bottlenecks.
The right approach is to hit scalability bottlenecks and fix
them.
Thanks,
Ingo
