[PATCH 0/8] correct load_balance()
Commit 88b8dac0 makes load_balance() consider other cpus in its group. But, there are some missing parts for this feature to work properly. This patchset correct these things and make load_balance() robust. Others are related to LBF_ALL_PINNED. This is fallback functionality when all tasks can't be moved as cpu affinity. But, currently, if imbalance is not large enough to task's load, we leave LBF_ALL_PINNED flag and 'redo' is triggered. This is not our intention, so correct it. These are based on v3.8-rc7.
