[PATCH v2 4/4] drm/virtio: Add memory barriers for capset cache.
From: David Riley <davidriley at chromium.org>
After data is copied to the cache entry, atomic_set is used indicate
that the data is the entry is valid without appropriate memory barriers.
Similarly the read side was missing the corresponding memory barriers.

[PATCH] drm/virtio: fix bounds check in virtio_gpu_cmd_get_capset()
This doesn't affect runtime because in the current code "idx" is always
valid.
First, we read from "vgdev->capsets[idx].max_size" before checking
whether "idx" is within bounds. And secondly the bounds check is off by
one so we could end up reading one element beyond the end of the
vgdev->capsets[] array.

[PATCH] drm/virtio: rework batching
Drop the virtio_gpu_{disable,enable}_notify(). Add a new
virtio_gpu_notify() call instead, which must be called whenever
the driver wants make sure the host is notified needed.
Drop notification from command submission. Add virtio_gpu_notify()
calls everywhere instead. This results in more batching because we now
notify only once for a series of commands. We already had that for page
flips,
