    s390/mm: align swapper_pg_dir to 16k · 0ccb32c9

    The segment/region table that is part of the kernel image must be
    properly aligned to 16k in order to make the crdte inline assembly
    work.
    Otherwise it will calculate a wrong segment/region table start address
    and access incorrect memory locations if the swapper_pg_dir is not
    aligned to 16k.
    
    Therefore define BSS_FIRST_SECTIONS in order to put the swapper_pg_dir
    at the beginning of the bss section and also align the bss section to
    16k just like other architectures did.
