Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core refactorings and improvements from Arnaldo Carvalho de Melo:
User visible changes:
- Add hint for 'Too many events are opened.' error message (Jiri Olsa)
Infrastructure changes:
- Protect accesses to map rbtrees with a lock and refcount struct map,
reducing memory usage as maps not used get freed. The 'dso' struct is
next in line. (Arnaldo Carvalho de Melo)
- Annotation and branch related option parsing refactorings to
share code with upcoming patches (Andi Kleen)
