It doesn't save too much cpu time as expected, just a cleanup.
Frankly I won't bother with this. It doesn't completely remove all

Folks,

Hi folks,
Lets kick off the virtio-gpu review process, starting with the virtio
protocol.
This is a tiny patch series for qemu. Patch #1 carries the header file
