I'm expecting that it will take some time until spec change will be merged and now leaning to apply this v1 patch to not hold the Venus work. Gerd, do you have objections? R-b/ack?

Applied patch to misc-next with edited commit message. Updating spec taking much time, not worth to hold this change longer. We'll add the rest of capsets later on. Thanks, Rui!

This definition is used fro qemu, and qemu imports this marco in the headers to enable venus for virtio gpu. So it should add it even kernel doesn't use this.
