  perf record: Ensure return non-zero rc when mmap fail (2016-02-29 12:44:15 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Check existence of frontend/backed stalled cycles in 'perf stat' (Andi Kleen)

- Avoid installing .o files from tools/lib/ into the python extension (Jiri Olsa)

- Rename the tracepoint '/format' field that carries the syscall ID from 'nr',
  that is also the name of some syscalls arguments, to "__syscall_nr", to
  avoid having multiple fields with the same name, that was breaking the
  python script skeleton generator from perf.data files (Taeung Song)

- Support converting data from bpf events in 'perf data' (Wang Nan)

Infrastructure:

- Split libtraceevent's pevent_print_event() (Steven Rostedt)

- Librarize some 'perf record' bits to allow handling multiple perf.data
  files per session (Wang Nan)

- Ensure return non-zero rc when mmap fail in 'perf record' (Wang Nan)
