[PATCH 00/10] nohz: Support sysidle (+ some more nohz kick cleanups)

From: Frederic Weisbecker
Date: Mon Jul 28 2014 - 13:37:56 EST


In this set, I have added Paul's acks and applied Peterz suggestion to
rename irq_work_void_on() to kick_cpu(), which I actually expanded to
kick_cpu_async() so to differentiate its behaviour from kick_all_cpus_sync().



Frederic Weisbecker (10):
smp: Introduce void kick_cpu_async()
nohz: Kick full dynticks timer targets with an empty IPI
rcu: Kick full dynticks CPU on extended grace period with kick_cpu_async()
nohz: Appropriate timekeeper kick on sysidle break
smp: Fast path check on IPI list
nohz: Define meaningful symbol for nohz full timekeeper
nohz: Enforce timekeeping on CPU 0
nohz: Fetch timekeeping max deferment only for timekeeper
nohz: Switch nohz full timekeeper to dynticks idle on top of sysidle detection
nohz: Warn on illegal timekeeper switch in nohz full
