There appears to be a couple of unused function that fedora 21 warns as being unused and then it treats those as errors. A patch has been created and submitted upstream. http://marc.info/?l=oprofile-list&m=140234661706876&w=2
Patches are included in oprofile-0.9.9-5.54.gb7e9a57.fc21.src.rpm so that oprofile builds on fc21. http://koji.fedoraproject.org/koji/taskinfo?taskID=7033767
