Hi folks, Continuing my journey into the KVM stage-2 page-table code, here are some fixes for a bunch of issues I spotted purely by code inspection. Most of these involve really unusual scenarios, but I'm a bit worried about the stage-2 fault on stage-1 page-table walk during instruction fetch from a read-only memslot, as that feels like it might be hittable with EFI. Anyway, feedback welcome, especially as this is a user-visible change.
