As requested, this version is a copy of the common version of ipc.h,
instead of the mips version.

The diff against the common version:
$ diff ./sysdeps/unix/sysv/linux/bits/ipc.h
./sysdeps/unix/sysv/linux/aarch64/bits/ipc.h
49,50c49
<     unsigned short int mode;		/* Read/write permission.  */
<     unsigned short int __pad1;
---
>     unsigned int mode;			/* Read/write permission.  */

<     unsigned short int __pad2;

>     unsigned short int __pad1;
