This is regarding memory page sharing.
I traced the code for page_sharing_nominate. But couldn't find the exact location
which requires HAP. So if somebody could tell me the location it would be a great help for me.
My other questions are,
I don't understand the role HAP plays in page sharing?
Why can't we use the shadow page tables with page sharing?

Please help.
