ipc.2: Fix prototype parameter types
The types for some of the parameters are incorrect (different than the kernel). Fix them. Below are shown the types that the kernel uses. ...... .../linux$ grep_syscall ipc ipc/syscall.c:110: SYSCALL_DEFINE6(ipc, unsigned int, call, int, first, unsigned long, second, unsigned long, third, void __user *, ptr, long, fifth) ipc/syscall.c:205: COMPAT_SYSCALL_DEFINE6(ipc, u32, call, int, first, int, second, u32, third, compat_uptr_t, ptr, u32, fifth) include/linux/compat.h:874: asmlinkage long compat_sys_ipc(u32, int, int, u32, compat_uptr_t, u32); include/linux/syscalls.h:1221: asmlinkage long sys_ipc(unsigned int call, int first, unsigned long second, unsigned long third, void __user *ptr, long fifth); .../linux$ function grep_syscall() { if !
