With the patch below now we have all as:

[acme@felicio linux]$ find tools/ -name "*.[ch]" | xargs grep 'include.\+perf_event\.h'
tools/perf/util/session.h:#include "../../../include/linux/perf_event.h"
tools/perf/util/header.h:#include "../../../include/linux/perf_event.h"
tools/perf/util/evsel.h:#include "../../../include/linux/perf_event.h"
tools/perf/perf.h:#include "../../include/linux/perf_event.h"
[acme@felicio linux]$

Can you try it so that I can get your Acked-by and Tested-by?
