Hi, Laurent,
I want to test this patch set and found that it does not apply on top
of latest usptream git, because of some changes in this merge window,
so better rebase.

callers to resolve a gfn when the associated pfn has a valid struct page
that isn't being actively refcounted (e.g. tail pages of non-compound
higher order pages). For a caller to safely omit FOLL_GET, all u

Introduce __kvm_follow_pfn, which will replace __gfn_to_pfn_memslot.
__kvm_follow_pfn refactors the old API's arguments into a struct and,

argument.
