xref issue #92 we're talking about these:

# define __NR_preadv 333
# define __NR_pwritev 334
# define __NR_rt_tgsigqueueinfo 335
# define __NR_perf_event_open 336
# define __NR_recvmmsg 337
# define __NR_fanotify_init 338
# define __NR_fanotify_mark 339
# define __NR_prlimit64 340
# define __NR_name_to_handle_at 341
# define __NR_open_by_handle_at 342
# define __NR_clock_adjtime 343
# define __NR_syncfs 344
# define __NR_sendmmsg 345
# define __NR_setns 346
# define __NR_process_vm_readv 347
# define __NR_process_vm_writev 348
# define __NR_kcmp 349

and I'm moving the x64 ones beyond sockets and ipc that are different from
x86 to here:

```
