This will be used i915 in forthcoming patches in order to measure the largest contiguous chunk of memory available for enabling chipset features. v2: Try to make the macro marginally safer and more readable by not depending upon the drm_mm_hole_node_end() being non-zero. Note that we need to open code list_for_each() in order to update the hole_start, hole_end variable on each iteration and keep the macro sane. v3: Tidy up few BUG_ONs that fell foul of adding additional tests to drm_mm_hole_node_start().
