Hi,
This version is based on [1], which try to not put cfs_rqs in throttled_hierarchy on the rq leaf_cfs_rq_list, simplify the leaf_cfs_rq_list maintenance and optimize the periodic load decay.
Vincent suggested moving throttled_hierarchy() outside list_add_leaf_cfs_rq() because the task will not be added in this case which is quite misleading.
When do that moving in propagate_entity_cfs_rq(), I found it has problem with propagation upwards. So add the fix in the first patch to be easier to backport, please see the details in its commit message.
