  Change the way that unmanaged pages are created.  Specifically,
  immediately flag any page that is allocated to a OBJT_PHYS object as
  unmanaged in vm_page_alloc() rather than waiting for a later call to
  vm_page_unmanage().  This allows for the elimination of some uses of
  the page queues lock.
  Change the type of the kernel and kmem objects from OBJT_DEFAULT to
  OBJT_PHYS.  This allows us to take advantage of the above change to
  simplify the allocation of unmanaged pages in kmem_alloc() and
  Remove vm_page_unmanage().  It is no longer used.
