Boris Ostrovsky f7c1a6c67f x86/kvm: Cache gfn to pfn translation ... commit 917248144d upstream. __kvm_map_gfn()'s call to gfn_to_pfn_memslot() is * relatively expensive * in certain cases (such as when done from atomic context) cannot be called Stashing gfn-to-pfn mapping should help with both cases. This is part of CVE-2019-3016.
