In order to free the hotplug cpu data and text, you'd have to make those sections page aligned - and then you have the question of how much space you are wasting in doing so. That will be variable over time as the code changes. Also, if you were to merge the hotplug cpu text and data to reduce the wastage, would that cause any architectures any issues?
