Subject[PATCH 0/4 v2] rcu: Fix some rcu uses in extended quiescent state
Date
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.

Frederic Weisbecker (4):
nohz: Split extended quiescent state handling from nohz switch
x86: Enter rcu extended qs after idle notifier call
x86: Call idle notifier after irq_enter()
rcu: Fix early call to rcu_irq_exit()
