    Include count of pagecache pages in show_mem() output
    
    The show_mem() output does not include the total number of pagecache
    pages.  This would be helpful when analyzing the debug information in
    the /var/log/messages file after OOM kills occur.
    
    This patch includes the total pagecache pages in that output.
