perf diff: Use llabs() with 64-bit values
To fix this build error on a debian mipsel cross build environment: builtin-diff.c: In function 'compute_cycles_diff': builtin-diff.c:649:10: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value] 649 | val = labs(pair->block_info->cycles_spark[i] - | ^~~~ Fixes: cebf7d51a6c3 ("perf diff: Report noisy for cycles diff") Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-pn7szy5uw384ntjgk6zckh6a@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
