Hi Andrey,
This is PULL request for big LITTLE MP v8 branch:
Major updates are:
- Based on v3.6-rc5
- new branch from Paulm: rcu-hotplug-v1, vincent:
scheduler-misc-v1 and sudeepk arm-multi_pmu_v1
- new version of patches from Morten: task-placement-v2
- config fragment updated for fast & slow cpu
Compile tested only.
