perf trace: Provide libtracevent with a kernel symbol resolver
So that beautifiers wanting to resolve kernel function addresses to names can do its work, now, for instance, the 'timer' tracepoints beautifiers works with 'perf trace', see the "function=tick..." part: # perf trace --event timer:hrtimer_start <SNIP> 0.000 timer:hrtimer_start:hrtimer=0xffff88026f3101c0 function=tick_sched_timer/0x0 expires=52098339000000 softexpires=52098339000000) 0.003 timer:hrtimer_start:hrtimer=0xffff88026f3101c0 function=tick_sched_timer/0x0 expires=52098339000000 softexpires=52098339000000) <SNIP> Reported-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: David Ahern <dsahern@gmail.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Stephane Eranian <eranian@google.com> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/n/tip-n4i0hxpbl1tnleiqkok47fw2@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
