_dl_get_thp_config has

  if (DL_MAP_DEFAULT_THP_PAGESIZE != 0)
    {
      GL(dl_elf_thp_pagesize) = DL_MAP_DEFAULT_THP_PAGESIZE;
      GL(dl_thp_mode) = thp_mode_madvise;
    }
  else
    {
      GL(dl_thp_mode) = __get_thp_mode ();
      if (GL(dl_thp_mode) == thp_mode_always
          || GL(dl_thp_mode) == thp_mode_madvise)
        GL(dl_elf_thp_pagesize) = get_capped_thp_size ();
      else
        GL(dl_elf_thp_pagesize) = 0;

      if (GL(dl_elf_thp_pagesize) == 0)
        {
          GL(dl_elf_thp_control) = dl_elf_thp_control_disabled;
          GL(dl_thp_mode) = thp_mode_not_supported;
        }
    }

In your case,  _rtld_global._dl_thp_mode should be thp_mode_not_supported.
what is _rtld_global._dl_thp_mode when __madvise is called?
