Hi Andrey,

big LITTLE MP v17 is ready for you to pull.

- Rebased over 3.10-rc1
- Stats: Total distinct patches: 41
  - New Patches:
    - master-wq-migration-v5: 5 (Already Applied for 3.11 by Tejun Heo).
      This is currently disabled by default and need an update in config
      fragment.

@Liviu/Steve: Can you please let us know if we can enable it?

    - master-task-placement-v2: 2 from Chris Redpath
    - master-task-placement-v2-sysfs: 1 from Chris Redpath

Hi Viresh,

We are still waiting for some workload automation test results before we can decide. Sorry I haven't replied yet to your other email, but we don't have the bandwidth in ARM at the moment to run the tests, so it will fall into your lap (or someone inside Linaro) to do the tests before we enable it. I want to see the impact of the patch before deciding.

Regards, Liviu
