    Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging
    
    virtio,pci: bugfixes
    
    Minor bugfixes all over the places, including one CVE.
    
    Additionally, a fix for an ancient bug in migration -
    one has to wonder how come no one noticed.
    
    The fix is also non-trivial since we dare not break all
    existing machine types with pci - we have a work around
    in the works, for now we just skip the work-around for
    old machine types.
    
    Great job by Hogan Wang noticing, debugging and fixing it,
    and thanks to Dr. David Alan Gilbert for reviewing the patches.
