It does not. I don't know about that seriers. The patches are part of the 
patchset that lead to my PAuth fixes a year ago. At that time, only beta spec 
was available, including obvious bugs (sysregs with duplicate opcodes), 
suspicious things (TCO being EL3) and generally being a beta. I thus sat on 
that part of the work until I now got time to rebase, clean and update to the 
released spec.

Meanwhile if there's a high-profile developer working on the same thing, I 
guess there's no point for me to carry on.
