Hm, I noticed this too late, but lots of architecture defconfig builds now produce 
a ton of warnings:

 In file included from /home/mingo/tip/kernel/sched/idle.c:19:0:
 /home/mingo/tip/kernel/sched/sched.h:1275:33: warning: 'sysctl_sched_features' defined but not used [-Wunused-variable]
  static const_debug unsigned int sysctl_sched_features =
                                  ^

I'm dropping this patch for now.

Thanks,

	Ingo
