Maybe Documentation/powerpc/cpu_families.rst should be updated as well.

Good idea it still needs Power9 too.

There's three "Appendix A"s in ISA v3.1.
There's one in Book I, and one in Book II.
And then the one you're referring to is not actually in Book III, it's
listed after Book III, and is apparently an appendix to all three books?
Which is just utterly confusing.
So I'll change it to say:
"Appendix A. Notes on the Removal of Transactional Memory from the Architecture"
Which is very long, but at least you can search for it.
cheers
