You're going to hate, but this is patch ordering fail. Imo this should be
one of the very first patches, at least before you kill obj->gtt_offset.
To increase your hatred some more, I have bikesheds on the names, too.
I think the best would be to respin this patch and merge it right away.
It'll cause tons of conflicts. But keeping it as no. 30 in this series
will be even worse, since merging the first 30 patches won't happen
instantly. So much more potential for rebase hell imo.
The MO for when you stumble over such a giant renaming operation should be
imo to submit the "add inline abstraction functions" patch(es) right away.
That way everyone else who potentially works in the same area also gets a
heads up.

To differentiate from the ppgtt offset I'd call this
i915_gem_obj_ggtt_offset.

Same here, I think we want ggtt inserted.

This is even more misleading and the real reasons I vote for all the ggtt
bikesheds: ggtt_size != obj->size is very much possible (on gen2/3 only
though). We use that to satisfy alignment/size constraints on tiled
objects. So the i915_gem_obj_ggtt_size rename is mandatory here.

Dito for consistency.
