Merge tag 'perf-core-for-mingo-20160429' 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:

 - Allow generate timestamped suffixed multiple perf.data files upon receiving
   SIGUSR2 in 'perf record', to slice a long running monitoring session, allowing
   to dump uninteresting sessions (Wang Nan)

 - Handle ENOMEM for perf_event_max_stack + PERF_SAMPLE_CALLCHAIN
   in perf_evsel__open_strerror(), showing a more informative
   message when the request call stack depth can't be allocated by
   the kernel (Arnaldo Carvalho de Melo)

Infrastructure changes:

 - Use strbuf for making strings in 'perf probe' (Masami Hiramatsu)

 - Do not use sizeof on pointer type, not a problem since its a pointer to
   pointer, fix none the less. Found by Coccinelle (Vaishali Thakkar)

Cleanups:

 - Fix for Coverity found issues in the bpf feature build test (Florian Fainelli)
