  SVN rev 181752 on 2008-08-15 09:08:35Z by kib
  
  MFC r177535 by peter:
  (Micro)optimization of cpu_switch for amd64.
  Because r173004 (pure kernel threads) is not MFCed to stable/7, I use
  P_KTHREAD flag from curthread->td_proc->p_flag instead of TDP_KTHREAD
  flag from curthread->td_pflags to test whether the fs/gs bases need to
  be restored [1].
  
  No objections for MFC from:     peter
  Suggested by:   jhb [1]
  
  MFC r180992:
  Bring back the save/restore of the %ds, %es, %fs and %gs registers for
  the 32bit images on amd64.
  
  The end result is almost complete syncronization of the
  amd64/amd64/cpu_switch.S between head and stable/7, besides TDP_KTHREAD
  difference.
