    kernel - VM rework part 17 - Cleanup
    
    * Adjust kmapinfo and vmpageinfo in /usr/src/test/debug.
      Enhance the code to display more useful information.
    
    * Get pmap_page_stats_*() working again.
    
    * Change systat -vm's 'VM' reporting.  Replace VM-rss with PMAP and
      VMRSS.  Relabel VM-swp to SWAP and SWTOT.
    
      PMAP	- Amount of real memory faulted into user pmaps.
    
      VMRSS	- Sum of all process RSS's in thet system.  This is
    	  the 'virtual' memory faulted into user pmaps and
    	  includes shared pages.
    
      SWAP	- Amount of swap space currently in use.
    
      SWTOT	- Total amount of swap installed.
    
    * Redocument vm_page.h.
    
    * Remove dead code from pmap.c (some left over cruft from the
      days when pv_entry's were used for PTEs).
