    sys/vm               vm_fault.c vm_object.c vm_object.h 
                         vnode_pager.c 
  Log:
   - Add a new object flag "OBJ_NEEDSGIANT".  We set this flag if the
     underlying vnode requires Giant.
   - In vm_fault only acquire Giant if the underlying object has NEEDSGIANT
     set.
   - In vm_object_shadow inherit the NEEDSGIANT flag from the backing object.
