    kernel - VM rework part 16 - Optimization & cleanup pass
    
    * Adjust __exclusive_cache_line to use 128-byte alignment as
      per suggestion by mjg.  Use this for the global vmstats.
    
    * Add the vmmeter_neg_slop_cnt global, which is a more generous
      dynamic calculation verses -VMMETER_SLOP_COUNT.  The idea is to
      return how often vm_page_alloc() synchronizes its per-cpu statistics
      with the global vmstats.
