I read it and it looks good to me, but it still needs a real reviewer approve.
You actually make TDI a variable-length instruction. Why not just emit "(uintptr_t)msg" no matter what?
Particularly, "enum stop_msg_present = -0x8000" is correct but subtle. I'd like to learn from other reviewers.

I’d like to have the improvements which we discussed for AArch64 also on PPC64 (+ a little more).
