So, this is not building on android env:
builtin-sched.c: In function 'process_lost':
builtin-sched.c:2646:2: error: unknown conversion type character 'l' in format
[-Werror=format=]
printf("lost %" PRI_lu64 " events on cpu %d\n", event->lost.lost,
sample->cpu);
^
builtin-sched.c:2646:2: error: format '%d' expects argument of type 'int', but
argument 2 has type '__u64' [-Werror=format=]
builtin-sched.c:2646:2: error: too many arguments for format

It doesn't build on the r15b as well.
I'll investigate after lunch.
