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

virtio, vhost, pc, pci: documentation, fixes and cleanups

Lots of fixes all over the place.

Unfortunately, this does not yet fix a regression with vhost
introduced by the last pull, the issue is typically this error:
    kvm_mem_ioeventfd_add: error adding ioeventfd: File exists
followed by QEMU aborting.
