    kernel - Fix improper OOM process kill when no swap configured
    
    * The avail_shortage calculation used by the pageout demon to track
      whether enough pages could be retired had a degenerate case which
      caused the demon to improperly believe that the machine was out of
      memory when it wasn't.
    
    * Generally would only happen if no swap was configured.
