    Remove map entry pageability property.
    
    Since the replacement of the zone allocator, kernel objects have been
    wired in memory. Besides, as of 5e9f6f (Stack the slab allocator
    directly on top of the physical allocator), there is a single cache
    used to allocate map entries.
    
    Those changes make the pageability attribute of VM maps irrelevant.
    
    * device/ds_routines.c (mach_device_init): Update call to kmem_submap.
    * ipc/ipc_init.c (ipc_init): Likewise.
    * kern/task.c (task_create): Update call to vm_map_create.
    * vm/vm_kern.c (kmem_submap): Remove `pageable' argument. Update call
    to vm_map_setup.
    (kmem_init): Update call to vm_map_setup.
    * vm/vm_kern.h (kmem_submap): Update declaration.
    * vm/vm_map.c (vm_map_setup): Remove `pageable' argument. Don't set
    `entries_pageable' member.
    (vm_map_create): Likewise.
    (vm_map_copyout): Don't bother creating copies of page entries with
    the right pageability.
    (vm_map_copyin): Don't set `entries_pageable' member.
    (vm_map_fork): Update call to vm_map_create.
    * vm/vm_map.h (struct vm_map_header): Remove `entries_pageable' member.
    (vm_map_setup, vm_map_create): Remove `pageable' argument.
