v1: (tested) idle GPU before and after unmaps. v2: (untested) Read GMCH_CTRL to find if VT-d is enable Pulled David's patch into the series Only stall for unmaps Add warning for list_empty && !rings_idle
v3: (still untested) Removed warning stuff, got rid of early exit in i915_gpu_idle completely Pulled logic to detect effected chipsets into a new function Left the interruptible=true logic because I still think it's required, and I can't see how it hurts terribly badly.
