s390 has an almost identical copy of the code in kernel/uid16.c. The problem here is that it requires calling the regular system calls, which the generic implementation handles correctly, but the internal interfaces are not declared in a global header for this. The best way forward here seems to be to just use the generic code and delete the s390 specific implementation. I keep the changes to uapi/asm/posix_types.h inside of an #ifdef check so user space does not observe any changes. As some of the system calls pass pointers, we also need wrappers in compat_wrapper.c, which I add for all calls with at least one argument. All those wrappers can be removed in a later step.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
