[PATCH v4 0/2] drm/virtio: Use vmalloc for command buffer alllocations.

From: David Riley
Date: Wed Sep 11 2019 - 14:14:13 EST

Userspace requested command buffer allocations could be too large
to make as a contiguous allocation. Use vmalloc if necessary to
satisfy those allocations.

v1: Initial version.
v2: Properly account for number of free descriptors required.
v3: Remove offset handling for vmalloc'd buffers.
v4: Rebase onto drm-misc-next.

David Riley (2):
drm/virtio: Rewrite virtio_gpu_queue_ctrl_buffer using fenced version.
drm/virtio: Use vmalloc for command buffer allocations.
