  Log:
  Fix just about as many bugs in my last commit here as there were lines that
  I changed.  That is never a good sign.
  1) only map 1 page at address zero, not 4096 pages
  2) page 1 starts at address 4096 (PAGE_SIZE) not 4095 (PAGE_MASK).  I
     don't even want to think what the pte's looked like.
  3) subtract the r/o page group start address from the end before
     converting it to a count.  Otherwise an extra page is mapped.
  
  If you were affected by this, the symptoms of this was a hang at boot
  after the spinner.  Sorry folks. :-(
