Ralf Baechle f5179287b0 MIPS: Fix randconfig build error.
CC      arch/mips/kernel/ptrace.o
In file included from arch/mips/kernel/ptrace.c:42:0:
arch/mips/kernel/ptrace.c: In function ‘mips_get_syscall_arg’:
/home/ralf/src/linux/linux-mips/arch/mips/include/asm/syscall.h:60:1: error: control reaches end of non-void function [-Werror=return-type]
cc1: all warnings being treated as errors
make[2]: *** [arch/mips/kernel/ptrace.o] Error 1
make[1]: *** [arch/mips/kernel] Error 2
make: *** [arch/mips] Error 2

Fixed by marking the end of mips_get_syscall_arg() as unreachable.

Ralf Baechle c0ff3c53d4 MIPS: Enable HAVE_ARCH_TRACEHOOK.
This enables /proc/<pid>/syscall and the ptrace PTRACE_GETREGSET and
PTRACE_SETREGSET operations.
