Hi Andrey,

Below is pull request for v7 of MP work. Following are the main changes: - Based on v3.6-rc3 - per-task-load-average-v3 - applied ARM-Add-HMP-scheduling-support-for-ARM-architecture to task-placement-v1 branch - applied Tixy's patch from fast-slow-cpu-dt-v1 to task-placement-v1 as they are somewhat related only.

NOTE: Compile tested only

In future i will be sending you PULL requests according to:

https://wiki.linaro.org/WorkingGroups/PowerManagement/Process/bigLittleMPTre...
