Peter, do you have more comments?

I'm not really a fan of this syscall is faster than exception stuff. Yes
it is for current hardware, but I suspect much of this will be a
maintenance burden 'soon'.

Anyway, I'll queue the patches tomorrow. I think the shadow stack thing
wants fixing though. The rest we can prod at whenever.

ok, will send follow up

thanks,
jirka
