[PATCH 1/5] virtio-gpu: add virtio_gpu_queue_ctrl_buffer_nolock
Add virtio_gpu_queue_ctrl_buffer_nolock function, which does the same as
virtio_gpu_queue_ctrl_buffer but does not take the virtqueue lock. The
caller must hold the lock instead.

Patches are looking good now, but they don't apply. What tree was used
to create them?
Latest virtio-gpu driver bits are in drm-misc-next (see
https://cgit.freedesktop.org/drm/drm-misc).
