It sure sticks out enough to make oneself ask that question.

I can only assume there was something in i915_request.h at some point 
which used it and some include hell made it the easiest solution. But 
it's a pure guess at this point.

I've tried moving it to i915_gem_context.h and it all still compiles 
fine. I better change it then..
