    vkernel - Refactor pmap
    
    * Refactor the pmap code.  Use vm_page locking to protect PTEs.
    
    * Change the accounting from using vm_page->hold_count to using
      vm_page->wire_count.
    
    * Replace unlocked pt/pd/pdp lookups with explicit page tests for non-kernel
      pmaps.
