    sys/amd64/amd64      trap.c 
    sys/i386/i386        trap.c 
  If the trap number stored in the trapframe is corrupted into a negative
  value, then we would use a negative index into the trap_msg[] array
  resulting in a nested page fault.  Make the 'type' variable holding the
  trap number unsigned to avoid this.
