Something like the following patch? It changes all occurrences of
"replacement" or "obsolete" (that I'm aware of) with "preferred over".

This patch does not change the phrase "please use kstrtoul instead",
as you called that correct. I could change it to something like "prefer
using kstrtoul instead" for consistent terminology; should I?
