    kernel - Implement segment pmap optimizations for x86-64 (4)
    
    * Fix pmap_pte_quick() when it is called on a VM object's simple pmap.
      Fixes a panic during postgres init w/ postgres/mmap.  Simple pmaps
      do not have PDP or PML4 pages or pv_entry's, only from PD on down.
    
    * Do some minor API work on the pte-indexing functions.
