looked at arch/vax/syscall.c and found that at line 75 this is missing:

struct trapframe * const exptr = tf;

and line 82 is to be changed from:
TDB(("trap syscall %s pc %lx, psl %lx, sp %lx, pid %d, frame %p\n",
            syscallnames[tf->tf_code], tf->tf_pc, tf->tf_psl,tf->tf_sp,
            p->p_pid,frame));

to

TDB(("trap syscall %s pc %lx, psl %lx, sp %lx, pid %d, frame %p\n",
            syscallnames[tf->tf_code], tf->tf_pc, tf->tf_psl,tf->tf_sp,
            p->p_pid,tf));

Holm
