Chris Wilson f6844a85e0 drm/i915/selftests: Replace opencoded clflush with drm_clflush_virt_range ... We occasionally see that the clflush prior to a read of GPU data is returning stale data, reminiscent of much earlier bugs fixed by adding a second clflush for serialisation. As drm_clflush_virt_range() already supplies the workaround, use it rather than open code the clflush instruction.
