  SVN rev 202983 on 2010-01-25 19:01:38Z by imp
  
  Store the mutex in the correct location.  Before, we were storing it
  in the pcb at the td_lock offset, rather than in the struct thread at
  the td_lock offset.  And we were storing a pointer to the old thread
  rather than to the mutex.  Why this didn't always kill us, I'll never
  know.
  
  Fix an obsolete comment and update the prototype in the comments.
  Also note what variables are in what registers since this function is
  a little complex...
  
  neel@ found this problem and proposed this fix.  This cures a number
  of different problem reports out there, and gets us booting octeon to
  the login prompt...
