Will:

I ran the OProfile testsuite on the OProfile 1.0.0 release and compared
the results to the OProfile 1.1.0rc1 release on the following systems:

        - IBM Power 7 running Red Hat Enterprise Linux Server release
        7.1 (Maipo)
        
        - IBM Power 8 big endian running Red Hat Enterprise Linux Server
        release 7.1 (Maipo)
        
        - IBM Power 8 little endian running Ubuntu 14.10

The tests ran without error on both OProfile releases.  No regression
errors were found with the release candidate.  Looks good to me.
