The old -realtime mlock=on|off parameter does exactly the same as the new -overcommit mem-lock=on|off parameter. Additionally, "-realtime" does not activate any additional "realtime" capabilities as the name might indicate. We should avoid to confuse the users this way, so let's deprecate the old -realtime option.
FYI libvirt currently uses -realtime mlock=on so will need adapting to cope with this change.
