[Qemu-devel] [PULL 11/12] dmabuf: add y0_top, pass it to spice

[Gerd Hoffmann <kraxel@redhat.com>]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Some scanouts during boot are top-down without it.

y0_top is set from VHOST_USER_GPU_DMABUF_SCANOUT code path in the last
patch of this series.

In current QEMU code base, only vfio/display uses dmabuf API. But the
VFIO query interface doesn't provide or need that detail so far.
