However, as you suggest, the other way around should be possible. Thanks for clearing that up.
Specifically, do you know the meaning of the end_brk field on the mm_context_t struct and if I need to checkpoint it on restart for non-MMU systems (and potentially do something more clever during restart on an MMU kernel?)
