... simply say: "Carve out initialization code needed by Dhyana into a
separate compilation unit."

That sentence is not needed - that fact is visible in the diff.

No need for that "(9)" - also visible from the diff and an
implementation detail.

That sentence is not needed for the same reason as above.

No, this should say: "Since Dhyana uses AMD functionality to a large
