Patch submitted to internal mailing list for development ACKs. This is by no means a critical item. It just cleans up the code base and puts x86_64 inline with i386. Also reduces the overall CPU debug messages being sent to /var/log/messages.
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.
