    Hmm... Thats sounds strange.

    Are you saying you cant change your scripts [But you'll have to anyway
    to parse pagesize=] ?

    I routinely use "cat /proc/xxx/numa_maps", and am stuck when a kernel
    displays nothing (it happened on some debian released kernels)

    Seeing pagesize=1GB is slightly better for human, and not that hard to
    parse for a program.

    By the way, "pagesize=4KiB" are just noise if you ask me, thats the
    default PAGE_SIZE. This also breaks old scripts :)
