The time32, stat64, and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/nios2 got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this.
