Mika has now closed the Jira issue. This patch still applies and looks
correct. Is it OK to be merged as-is?

There's a bit too much stuff in-flight to fix up error capture for ppgtt.
I think it's better to stall this patch here until that work is completed.
Please coordinate with Mika here.

[Intel-gfx] [PATCH 35/43] drm/i915/bdw: Make sure error capture keeps working with Execlists
From: Oscar Mateo
Since the ringbuffer does not belong per engine anymore, we have to
make sure that we are always recording the correct ringbuffer.
TODO: This is only a small fix to keep basic error capture working, but
we need to add more information for it to be useful (e.g. dump the
context being executed).
v2: Reorder how the ringbuffer is chosen to clarify the change and
rename the variable, both changes suggested by Chris Wilson. Also,
add the TODO comment to the code, as suggested by Daniel.
