  Log:
  The stack frame available from a signal to user mode stores the fault address
  in tf_err.  The PGEX bits that used to be stored in tf_err are lost.
  
  When a process a virtual kernel (p->p_vkernel != NULL), store the PGEX bits
  in the high 16 bits of the tf_trapno field so the virtual kernel can
  figure out whether the page fault was a read fault or a write fault.
