Memory addresses are for addressing memory. If you want space for extra flags, create a struct with a 'flags' member.

Tell that to Intel and AMD who are proposing to let programs use those bits for whatever they want. As if they completely forgot the entire purpose of "canonical" addresses and "32 bit clean" programs.
