[Xen-devel] [PATCH] nestedhvm: fix write access fault on ro mapping

[Christoph Egger <Christoph.Egger@xxxxxxx>]

Fix write access fault when host npt is mapped read-only.
In this case let the host handle the #NPF.
Apply host p2mt to hap-on-hap pagetable entry.
This fixes the l2 guest graphic display refresh problem.
