[PATCH v8 00/12] Enable i915 perf stream for Haswell OA unit

[Robert Bragg]

Rebased on nightly, and updated as per review from Matt and Chris

The first patch from Chris adds an i915_gem_context_pin_legacy() utility that
I'm depending on now - though it doesn't really form part of the i915-perf
series proper. I'm assuming Chris plans to send a version of this to the list
himself with a proper commit message.
