Is it OK? Calling functions from inline assembly is always a bit iffy. For example, your code lacks clobbers for the vector registers (if present) and the condition code register. I don't know if s390/s390x has a red zone, or specific call frame setup requirements (the psABI is ambiguous regarding the latter for functions whose arguments all fit into registers, as it is the case here). I would suggest not to use inline assembly for this purpose.
