Merge tag 'perf-core-for-mingo-20160615' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

- Add --ldlat option to 'perf mem' to specify load latency for loads
  event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

Build fixes:

- Fix libunwind related compile error for static cross build (He Kuang)

Infrastructure changes:

- UI refactorings to support headers with multiple lines, non-evsel
  hists browsers, toggle showing callchains, etc (Jiri Olsa)

- More prep work for caching probe definitions, paving the way
  for supporting SDT (Statically Defined Traces) userspace probes (Masami Hiramatsu)

- Handle NULL at perf_config_set__delete() (Taeung Song)
