This should be book3s_emulate.c.
Any reason we can't make that 00dddd00 opcode as breakpoint common to
all powerpc variants ?
I can't think of a good reason. We use a hypercall on booke (which traps
into an illegal instruction for pr) today, but I don't think it has to
be that way.
Given that the user space API allows us to change it dynamically, there
should be nothing blocking us from going with 00dddd00 always.
