Subject: drm: use page flip event to signal flip completion
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We don't actually know which frame number the flip will complete on, so
userspace needs a specific flip notification to tell it when the last flip
completed.
