[Regression Potential] The proposed patch has been merged upstream, so there shouldn't be potential regression. Also These changes are to code that only gets compiled on arm64, so there's no risk to other architectures. [Other Info] After running crash from trusty, the failure log in [1] can be observed. Then I built crash from wily directly, the similar failure[2] can be observed too. [1] failure log ubuntu@am2:~/git/crash-wily$ sudo crash ~/vmlinux crash 7.0.3 Copyright (C) 2002-2013 Red Hat, Inc.
