Hi, Stefano!

I'm just curious if the below is on your TODO list [1]:

3. Future Directions:

Allow users to optionally share *mfn-contiguous* pages.

What is the use case for that?
No real use-case at the moment, but we might have one: for instance,
sharing some memory which is used by device firmware and domains.
But in this case iomem could probably help...

Yes, that would be iomem. Shared memory is more between domains.
