2012-07-16: Initial integration tree build and boot tested and available for integration into linux-linaro
[dzin, 2012-08-22] This is ongoing work for 6 months or so. Estimate completion 13.02
Included Vincent's sched-pack-small-tasks-v1 and Preeti's per-entity-load-tracking-with-core-sched-v1 patches to v11 branch. Facing compilation issues with Preeti's patches.
Divided v12 branch into master and experimental.
2012-12-07: Removed experimental branch as it might never be required. Topic based branches must be used instead.
2013-01-04: Removed Interactive governor branches as they are no more required.
[ototo, 2013-02-01] Moving to the Feb 2013 as a recurring task.
2013-08-26: This task is now moved to ARM LT. Marking as done.

Meta:
Headline: Ongoing maintenance of b.L MP feature tree that tracks interesting patchsets for b.L MP work
