  SVN rev 180393 on 2008-07-09 19:44:37Z by peter
  
  Band-aid a problem with 32 bit selector setup.
  
  Initialize %ds, %es, and %fs during CPU startup.  Otherwise a garbage
  value could leak to a 32-bit process if a process migrated to a different
  CPU after exec and the new CPU had never exec'd a 32-bit process.
  
  A more complete fix is needed, but this mitigates the most frequent
  manifestations.
