Is there any documentation available of what is the exact semantics of the
functions that have to be implemented for additional architectures?

I could look at rseq-skip.h and e.g. rseq-x86.h and try to figure out what
would be the correct implementation for s390. But having that somewhere
written down, e.g. as comments in one of the implementations, would be very
helpful.
