It's not that I care strongly about the interface, my main point is that the changelog doesn't describe why one interface was used instead the other.
I suspect the current approach was taken because it follows the same scheme as 32-bit ARM. If both methods are sufficient (Kees would have a better idea than me on that), then I don't have a strong preference.
Using the regset would probably address Oleg's comment, and would keep the implementation architecture specific. You could even share the NT_S390_SYSTEM_CALL number, but I don't know if there any downsides to doing that.
