Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging

pc, pci, virtio: fixes, features

A bunch of fixes all over the place.
A new vmcore device - the user interface around it is still somewhat
controversial, but I feel most of the code is fine, suggestions can be
addressed by adding patches on top.
