    kernel - Remove unused pmap_list
    
    * pmap_list was used in the (now removed) 32-bit pmap code because
      expansion of the kernel_pmap potentially required updating the PT
      pages in all existing user pmaps.  The 64-bit pmap code does not
      need to do this so the list can be removed.
    
    * Removes a global spin-lock from the pmap creation and release path.
      Not a major factor for performance but a nice cleanup.
