I did consider that approach, but it was much more code to write the script than
to modify smaps ;-). Longer term, I think it would be good to have it in smaps
because its more accessible. For the contpte case we would need to add a bit to
every pagemap entry to express that. I'm not sure how palletable that would be
for a arch-specific thing?

Thanks for the script anyway!
