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]
