...like we would have from "arch_free_pages()"". This would be the same interface we are using for free page hinting - and it could even be made configurable in the guest. The current approach we are discussing internally for details about Nitesh's work ("how the magic inside arch_fee_pages() will work efficiently) would allow this as far as I can see just fine.
