    [S390] revert add_active_range() usage patch. · bcc8bcb1
    Heiko Carstens authored
    Commit 7676bef9 breaks DCSS support on
    s390. DCSS needs initialized struct pages to work. With the usage of
    add_active_range() only the struct pages for physically present pages
    are initialized.
    This could be fixed if the DCSS driver would initiliaze the struct pages
    itself, but this doesn't work too. This is because the mem_map array
    does not include holes after the last present memory area and therefore
    there is nothing that could be initialized.
    To fix this and to avoid some dirty hacks revert this patch for now.
    Will be added later when we move to a virtual mem_map.
