I have changed a bit the first patch by adding a "rcu_ext_qs" parameter in tick_nohz_enter_idle() so we just need to toggle that parameter to false when rcu_enter_nohz() is called separately. That's less confusing and more consistant than calling tick_nohz_stop_sched_tick() instead of tick_nohz_enter_idle() when rcu dynticks idle mode is handled separately.
It's an important enough change that I thought I had to drop all the acks in the first patch.
Also it adds a new fix for a new bug detected in patch 4.
The powerpc case is trickier so I prefer to get that pile handled before.
Thanks.
