Subject: Fix "Unable to open cpu_type file for reading" for IBM POWER7+
Git-commit: 88ed74bade0096042d643a6d7e68c2cbc4b6e34d
Date: Thu Jan 9 15:07:21 2014 -0600

Fix "Unable to open cpu_type file for reading" for IBM POWER7+
    
    Using operf to do profiling on an IBM POWER7+ may result in
    the following error message:
    
    	Unable to open cpu_type file for reading
    
    This patch fixes the problem.  There is also a simple workaround of
    running 'opcontrol --init'.
