  perf jit: add source line info support (2016-02-05 12:33:09 -0300)

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

User visible fixes:

- Handle spaces in file names obtained from /proc/pid/maps (Marcin Ålusarz)

New features:

- Improved support for java, using the JVMTI agent library to do jitdumps
  that then will be inserted in synthesized PERF_RECORD_MMAP2 events via
  'perf inject' pointed to synthesized ELF files stored in ~/.debug and
  keyed with build-ids, to allow symbol resolution and even annotation with
  source line info, see the changeset comments to see how to use it (Stephane Eranian)

Documentation:

- Document mmore variables in the 'perf config' man page (Taeung Song)

Infrastructure:

- Improve a bit the 'make -C tools/perf build-test' output (Arnaldo Carvalho de Melo)

- Do 'build-test' in parallell, using 'make -j' (Arnaldo Carvalho de Melo)

- Fix handling of 'clean' in multi-target make invokations for parallell builds (Jiri Olsa)
