Hi Andrey,
This is PULL request for big LITTLE MP v8 branch:
Merged into linux-linaro-core-tracking, the tag is llct-20120917.0.
Thanks, Andrey
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.
