    Subject[PATCH 3.11 034/233] perf scripting perl: Fix build error on Fedora 12
    Date
    3.11.10.4 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Arnaldo Carvalho de Melo <acme@redhat.com>

    commit 3b16ff89676d9902dc39976aee3cb0314ee37d93 upstream.

    Cast __u64 to u64 to silence this warning on older distros, such as
    Fedora 12:

    CC /tmp/build/perf/util/scripting-engines/trace-event-perl.o
    cc1: warnings being treated as errors
    util/scripting-engines/trace-event-perl.c: In function ‘perl_process_tracepoint’:
    util/scripting-engines/trace-event-perl.c:285: error: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘__u64’
    make[1]: *** [/tmp/build/perf/util/scripting-engines/trace-event-perl.o] Error 1
    make: *** [install] Error 2
    make: Leaving directory `/home/acme/git/linux/tools/perf'
    [acme@fedora12 linux]$
