Merge remote-tracking branch 'mst/tags/for_anthony' into staging

acpi,pci,pc,fedora,virtio fixes and enhancements

This includes some Preparatory patches for cpu hotplug for q25 and memory
hotplug by Igor, tests and memory mapping change
by Laszlo and pci reset cleanup by Paolo.
There are also some fixes for fedora and virtio:
included here since they are test blockers for me.
