Hi Arnd,

The IPC system call handling is highly inconsistent across architectures,
some use sys_ipc, some use separate calls, and some use both.  We also
have some architectures that require passing IPC_64 in the flags, and
others that set it implicitly.
...
We already have a gap at 366-377 from when we tried to add the split IPC
calls a few years back.

I guess I don't mind leaving that gap and using the common numbers as
you've done here.

But it would be good to add a comment pointing out that we have room
at 366 for more arch specific syscalls as well.

cheers
Guess I sent that one twice. 🤦

cheers
