It looks more logical, indeed to have the engine in it, but at
some point you call

	spin = spin_sync(gem_fd, 0, I915_EXEC_RENDER);

In the previous patchset I had created two branches of spin_sync,
one that took flags and one that took intel_execution_engine2,
but it looked to much of useless code.

In this case I could either create a dummy engine to make things
work with intel_execution_engine2 or just use flags and minimise
the changes.

In this patch there is still the problem of 4/5 subtests failing,
but we can discuss that offline and, as you noticed, the
igt_dummyload commit lost in the meanders of rebasing.

Thanks,
Andi
