[PATCH] nouveau/fence: handle cross device fences properly. (v3)
From: Dave Airlie <airlied at redhat.com>
This is the 3rd iteration of this after talking to Ben and
Danilo, I think this makes sense now.
The fence sync logic doesn't handle a fence sync across devices
as it tries to write to a channel offset from one device into
the fence bo from a different device, which won't work so well.
This patch fixes that to avoid using the sync path in
