Arnaldo Carvalho de Melo 699c12a7cc perf intel-pt: Update documentation about context switch events 
Since the unprivileged sched switch event was added in perf, PT doesn't
need need perf_event_paranoid=-1 anymore for per cpu decoding.

Add a note stating that that is only needed for kernels < 4.2.
