    Subject[PATCH 1/8] perf evsel: Fix a build failure on cross compilation
    From: Namhyung Kim <>

    The commit c410431cefefd ("perf tools: Reconstruct event
    with modifiers from perf_event_attr") added the line, but
    it's broken since it needs to go up 3 directories to get
    to the kernel root directory, not 2.

    However host gcc contains /usr/local/include in its
    search path, so that it can find the perf_event.h in
    /usr/include/linux. This is why we didn't notice the
    problem yet. But when I tried to cross compile, it
    appears like:

    CC util/evsel.o
    util/evsel.c:18:44: error: ../../include/linux/perf_event.h: No such file or directory
    make: *** [util/evsel.o] Error 1

    Looking at the source, it isn't needed at all as evsel.h
    already included the perf_event.h. So simply removing it
    would solve the problem.
