Please update you MESA checkout again. The patches to enable proper
Wayland support with etnaviv have landed just yesterday.

You can get around this by using a newer kernel. Etnaviv on 4.9 is
putting a lot of of stress on the CMA allocator, leading to those
messages (which are really just informational). Newer versions of the
kernel driver have grown a suballocator, which reduces the CMA stress to
almost 0.
