perf bench mem: Ignore export.h related changes to mem{cpy,set}.S
Ignore export.h and EXPORT_SYMBOL in: 784d5699eddc ("x86: move exports to actual definitions") We're not dragging this stuff, not useful in tools/ This silences the following warnings while building perf: Warning: tools/arch/x86/lib/memcpy_64.S differs from kernel Warning: tools/arch/x86/lib/memset_64.S differs from kernel Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-h9vw3pe0fq79zmyqsfr0s0mo@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
