    kernel - Remove most global atomic ops for VM page statistics
    
    * Use a pcpu globaldata->gd_vmstats to update page statistics.
    
    * Hardclock rolls the individual stats into the global vmstats structure.
    
    * Force-roll any pcpu stat that goes below -10, to ensure that the low-memory
      handling algorithms still work properly.
