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'.
