perf beauty mmap: Print mmap's 'offset' arg in hexadecimal
Also to make it match 'strace' output, for regression testing. Both now produce this option, when 'perf trace' uses a .perfconfig asking for the strace like output: mmap(0x7faf66e6a000, 1363968, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x22000) = 0x7faf66e6a000 Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-27qhouo1kaac2iyl85nfnsf5@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
