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

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

New, user visible features:

  - Add --buildid-all option to 'perf record' to avoid processing
    samples, just collecting build-ids for _all_ the DSOs that appears
    in PERF_RECORD_MMAP records (Namhyung Kim)

  - Add some more usage tips to appear in the hists browser
    (top & report) (Namhyung Kim, Andi Kleen)

  - Fix mmap2 event allocation in synthesize code, where we were
    allocating space just for PERF_RECORD_MMAP, the older variant,
    which could lead to corner case problems (Wang Nan)

Infrastructure fixes:

  - Make list.h self-sufficient, removing one more reference to
    kernel headers that lead to recent breakage when some rculist
    change was made in the kernel sources. (Josh Poimboeuf)

    Add missing NORETURN define for parse-options.h in
    tools/lib/subcmd (Josh Poimboeuf)

  - Fallback to srcdir/Documentation/ when not finding tips.txt
    elsewhere (Namhyung Kim)
