Re: [PATCH -tip 0/2] Temporary RCU fixes for notrace and hotplugCPU

[Ingo Molnar]

FYI, -tip testing found a new build warning on SH caused by the RCU 
tree (i suspect this warning triggers on other architectures as 
well):

/home/mingo/tip/kernel/rcutree.c:88: warning: '__rcu_offline_cpu' 
declared 'static' but never defined

it's harmless, but since we are generally trying to fix all warnings 
and gravitate towards more and more -Werror subsystems, it would be 
nice to fix this.
