perf diff: Use llabs() with 64-bit values
To fix these build errors on a debian mipsel cross build environment: builtin-diff.c: In function 'block_cycles_diff_cmp': builtin-diff.c:550:6: 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] 550 | l = labs(left->diff.cycles); | ^~~~ builtin-diff.c:551:6: 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] 551 | r = labs(right->diff.cycles); | ^~~~ Fixes: 99150a1faab2 ("perf diff: Use hists to manage basic blocks per symbol") 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>
