perf bench numa: Share sched_getcpu() __weak def with cloexec.c (2015-05-18 12:36:46 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Fix "Command" sort_entry's cmp and collapse function (Jiri Olsa)
- Load map's symtab before 'perf probe' glob matching (Wang Nan)
- Set vmlinux_path__nr_entries to 0 in vmlinux_path__exit, to fix
the use case where this code is called multiple times, which wasn't
that common when it was introduced but seems to be now (Wang Nan).
Infrastructure:
- Protect dso symtab and cache operations with a mutex (Namhyung Kim)
- Make all refcnt operations use atomic.h (Arnaldo Carvalho de Melo)
- Install libtraceevent.a into libdir (Wang Nan)
Build fixes:
- Fix one build failure on RHEL5 by making 'perf bench numa' use the
__weak sched_getcpu() provided by cloexec.h (Arnaldo Carvalho de Melo)
- Fix dwarf-aux.c compilation on i386 (Jiri Olsa)
