Hi Arnaldo

Please don't forget these.  Intel PT is broken on 4.3 without them i.e.

$ tools/perf/perf --version
perf version 4.3.rc1.gd25ed
$ tools/perf/perf record -e intel_pt//u uname
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for
event (sched:sched_switch).

Regards
Adrian
