Good question. The patches adding stuff to i915.rst are the
hardest ones to produce, in the sense that it is not easy to have
a common criteria about when creating or not a new section.

I tried to follow the same as other things for the same type, but
it is hard to classify.

The main point is that they should be somewhere there, in order to start
producing errors when building the docs. Reorganizing those markups should
be easily done once all files with kernel-docs gets added there.

Anyway, I'll keep this under:

	Other GT functionality

Section. We can shift things later on as needed.

Makes sense. I'll place GTT together with GGTT.
