  Log:
  Removed `kstack' and associated mistranslations in kvtophys().
  Correct translations would have been null.  However, kstack was
  the top of the kernel stack instead of the base of the kernel stack
  like it was when the kernel exported it, so the area above the
  kernel stack was mistranslated and the kernel stack was not
  translated.  This bug was depended on to compensate for the wrong
  value of kstack - to read the pcb, instead of just using the address
  of the pcb, we used the mistranslated address of kstack, which
  happened to be the same (curpcb = kstack - 0x2000).
  
  This area is simpler than it used to be now that the kernel stack
  address is per-process.  The code still seems to be more complicated
  than necessary - the `found_pcb == 0' case seems to be unused.
