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.
