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

Pull perf/core improvements from Arnaldo Carvalho de Melo:

User visible:

  * Improve 'perf probe' error messages, moving some diagnostic messages to
    only appear in --verbose mode and fixing up some error reporting related
    to variables and struct members. (Masami Hiramatsu)

  * Reflow 'perf timechart' man page. (Stanislav Fomichev)

Developer stuff:

  * Be more precise when reporting missing libraries in a static tool build.
    (Arnaldo Carvalho de Melo)

  * Show error messages from the multiple make invoked from 'make build-test'.
    (Arnaldo Carvalho de Melo)
