Make sure that all the variables are properly initialized. Remove the code that verifies the core to enable using get_schedaffinity since that make it impossible to change the cpu for different tests. Change the cpu_to_lock to an int, it really didn't need to be a long. Fix a few missing tests. Test: Ran unit tests. Test: Built the tests and ran on different cpus, verifying that the Test: chosen cpu was correct. Test: Created an xml file that had different cpus for different tests Test: and verified that it locked to each cpu properly. Change-Id: Ie7b4ad8f306f13d6e968d118e71bb5dc0221552a
