[PATCH v2 0/4] Add ftrace config and refactor several parts

[Taeung Song]

Hi, :)

Lately I sent several patches.
But they need to be modified so I send v2 packing them.

v2:
 - Check the return of perf_config() and
 warn the user with config error message (Arnaldo)
 - Change commit messages (Jiri)
 - Add only one macro instead of two macros (Jiri) 

Taeung Song (4):
  perf tools: Create for_each_event macro for tracepoints iteration
  perf ftrace: Add ftrace.tracer config option
  perf tools: Check NULL after zalloc() and Use zfree() instead of
    free() in parse-events.c
  perf tools: Increase index if perf_evsel__new_idx() succeeded
