Hi Andrey,

Please PULL b.L MP V11 branch from my tree. Pull request is generated against v3.7-rc3:

Thanks Viresh.

Updates:
-------
- Based on v3.7-rc3
- Stats:
 - Total Patches: 70
 - New Patches: 22
   - per-task-load-average-v3-merged: 1 by Peter Z.
   - per-entity-load-tracking-with-core-sched-v1: 15 by Preeti

My understanding was that this patchset by Preeti wasn't well received by the maintainers and is being reworked. Do we have an ETA from Preeti for the updates? I'm a little concerned that since this patchset isn't mandatory for the b.L MP solution, we might get distracted by it.

Having said that, we should still pay close attention to it since we obviously care about the changes.

   - sched-pack-small-tasks-v1:6 by Vincent

My suggestion is to add a list of patchsets (with branch names) for things that might be of interest to the audience but haven't been merged yet e.g. your patches for timer/workqueue migration.

Kevin and I have also spoken regarding resurrecting the Adaptive NO HZ port for ARM. Kevin will maintain that going forward. So we should look at getting that merged too in the next cycle.
