commit 45c2935e88d1eaf34c0769f9b514c0dcb0e43c1d
Author: William Cohen <wcohen@redhat.com>

    Correct IBM Power7 and Power8 computation of PAPI_L1_DCA
    
    When reviewing the test results for IBM Power7 and Power8 Michael
    Petlan found that the PAPI_L1_DCA preset was incorrectly computed.
    The L1 cache misses need to be subtracted rather than added to the
    result.
