Hi All,

I thought I would try my luck with this pair of patches...

Ack on the idea.

Actually I have a script to do just this, but it's based on pagemap (attaching the script at the end).

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!
