After transition from long to kernel_ulong_t we no longer need tcp->ext_arg, and therefore a function to access it is also no longer needed. * defs.h (getarg_klu): Remove prototype. * util.c (getarg_klu): Remove. (printargs): Access tcp->u_arg directly * bjm.c (SYS_FUNC(init_module)): Likewise. * clone.c (SYS_FUNC(unshare)): Likewise. * fadvise.c (SYS_FUNC(fadvise64)): Likewise. * kcmp.c (SYS_FUNC(kcmp)): Likewise. * kexec.c (SYS_FUNC(kexec_file_load)): Likewise. * keyctl.c (SYS_FUNC(keyctl)): Likewise. * lookup_dcookie.c (SYS_FUNC(lookup_dcookie)): Likewise. * mem.c (do_mprotect): Likewise. * mq.c (SYS_FUNC(mq_timedsend), SYS_FUNC(mq_timedreceive)): Likewise. * pkeys.c (SYS_FUNC(pkey_alloc)): Likewise. * prctl.c (print_prctl_args, SYS_FUNC(prctl), SYS_FUNC(arch_prctl)): Likewise.
