Vincent Guittot 4e5160766f sched/fair: Propagate asynchrous detach ...

A task can be asynchronously detached from cfs_rq when migrating
between CPUs. The load of the migrated task is then removed from
source cfs_rq during its next update. We use this event to set
propagation flag.

During the load balance, we take advantage of the update of blocked
load to propagate any pending changes.

The propagation relies on patch:

  "sched: Fix hierarchical order in rq->leaf_cfs_rq_list"

... which orders children and parents, to ensure that it's done in one pass.
