We are planning to upstream our Nios II kernel (arch/nios2) to mainline. But it doesn't support generic syscall ABI yet (It requires an updated Glibc port as well). The question is, is it a requirement for new arch to support generic syscall ABI when upstreaming? Can we upstream a non-generic syscall ABI first and migrate to generic syscall ABI in future? Thanks. Regards LFTAN
