This still does not contain the dmesg.  I need that in order to figure out
where in the trace that the OOM is occurring.  Chris, it's possible that your
trace-cmd suggestion is actually causing a problem here because trace-cmd
itself is getting OOM'd.  I'd suggest using the trace buffers directly.

I'd also really like to see how many pages the i915 code believes it has pinned
each time the shrinker is called during all this.
