With today's -tip there's a new warning on UP builds:

  /home/mingo/tip/kernel/sched/deadline.c:993: warning: 'pull_dl_task' declared 'static' but never defined

And in general the #ifdef happiness of deadline.c is rather sad:

 comet:~/tip> grep '#ifdef' kernel/sched/deadline.c 
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SCHED_HRTICK
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SCHED_HRTICK
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SCHED_HRTICK
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP
 #ifdef CONFIG_SMP

All that needs to be cleaned up.

Thanks,

	Ingo
