    I wish life were that simple. Unfortunately, struct page isn't the only
    problem with these abominations: the system can run out of kvm for
    vm_area_struct, task_struct, files... Personally, I *never* want to see
    those data structures being kmap()'d as it would hurt kernel code quality
    whereas a 4G/4G split is well confined, albeit sickening.
