Taken from: https://lkml.org/lkml/2013/6/20/80

Fix the following errors on gcc 4.8.1 / x86:

bench/numa.c: In function worker_thread:
bench/numa.c:1113:20: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
    if (diff.tv_sec >= g->p.nr_secs) {
                    ^
bench/numa.c:1161:6: error: format %lx expects argument of type long unsigned int, but argument 5 has type u64 [-Werror=format=]
      process_nr, thread_nr, runtime_ns_max / bytes_done, val);
      ^
