tools headers: Syncronize mman.h ABI header
To add support for the MAP_SYNC flag introduced in: b6fb293f2497 ("mm: Define MAP_SYNC and VM_SYNC flags") Update tools/perf/trace/beauty/mmap.c to support that flag. This silences this perf build warning: Warning: Kernel ABI header at 'tools/include/uapi/asm-generic/mman.h' differs from latest version at 'include/uapi/asm-generic/mman.h' Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Dan Williams <dan.j.williams@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jan Kara <jack@suse.cz> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-14zyk3iywrj37c7g1eagmzbo@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
