You missed GEN_FOREVER a bit below here in a comment.

commit ac657f6461e5 ("drm/i915: Introduce IS_GEN macro") introduced GEN_FOREVER that was never used. My first attempt was to rename it to FOREVER since GEN is already part of the macro. Then I used coccinelle to change all -INTEL_GEN(e1) >= e2 +INTEL_GEN_RANGE(e1, e2, FOREVER) -INTEL_GEN(e1) <= e2 +INTEL_GEN_RANGE(e1, 0, e2) and I liked it. However I didn't like very much the remaining INTEL_GEN(dev_priv) < n and: INTEL_GEN(e1) < n INTEL_GEN_RANGE(e1, 0, n - 1) didn't make much sense either. So INTEL_GEN use for > or < seems a better unified way for unlimited bounds. So, no reason to keep GEN_FOREVER here. Let's kill before someone start using it.
