[Intel-gfx] [PATCH v2 20/22] drm/i915: Remove i915_address_space.start

2017-02-10 Thread Chris Wilson
Once upon a time, back in the UMS days, we supported userspace initialising the GTT and sharing portions of the GTT with other users. Now, we own the GTT (both global and per-process) and the tables always start at 0 - so we can remove i915_address_space.start and forget about this old complication
