Not that it matters that much, but QEMU emulates Books I and II as well,
doesn't it?

Book I, Power ISA User Instruction Set Architecture,
covers the base instruction set and related facilities
available to the application programmer.

Book II, Power ISA Virtual Environment Architecture,
defines the storage model and other instructions and
facilities that enable the application programmer to cre-
ate multithreaded programs and programs that interact
with certain physical realities of the computing environ-
ment.

Book III, Power ISA Operating Environment Architec-
ture, defines the supervisor instructions and related
facilities.

Anyway, I'm OK with either name.
