Include count of pagecache pages in show_mem() output

Browse Source 
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.
