The patches look good, but what's your plan for dealing with other KMS
apps such as Wayland compositors (weston is also affected by this, I
assume so is gnome-shell, maybe more)? I was thinking it might be good
to have a backup plan in the kernel, e.g. copying from the BO passed in
by userspace to a different BO if the former doesn't match the hardware
size.
