Change parameter types of s390's compat ipc syscall from unsigned long to compat_ulong_t to enforce zero extension of these parameters.
This is not really a bug, since s390_ipc compat syscall is only a wrapper to the generic compat_sys_ipc() syscall, which performs correct zero and sign extension.
This was introduced with commit 56e41d3c5aa8 ("merge compat sys_ipc instances").
