The test checks the residency in a given RC6 state or any deeper states that are also enabled. For example the RC6 subtest checks the combined residency in RC6/RC6P/RC6PP. Since the kernel reported value for the RC6 residency doesn't include the RC6P or RC6PP residency we need to adjust the RC6 value accordingly. A similar adjustment is needed for the RC6P subtest.
