Message:

bugref:8087: Additions/x11: support non-root X server: add host flags location reporting to the kernel graphics driver in preparation for adding IRQ handling. Among other things, the host uses the flags, which it places at the location reported/requested by the guest in video RAM, to tell the guest what event the IRQ was sent in response to.
