Applied your patch to see if sheds light on a problem. Saw this 
compiling the kernel:

kernel/events/proc_perf_events.c: In function ‘perf_events_proc_show’:
kernel/events/proc_perf_events.c:175:5: warning: format ‘%llu’ expects 
argument of type ‘long long unsigned int’, but argument 3 has type ‘long 
int’ [-Wformat]
