The time32, stat64, rlimit and renameat entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/hexagon got added but are no longer enabled by default for new architectures. As a side-effect, calling an unimplemented syscall now return -ENOSYS rather than branching into a NULL pointer.
