  SVN rev 182755 on 2008-09-04 13:51:08Z by kib
  
  MFC r182684:
  
  - When executing FreeBSD/amd64 binaries from FreeBSD/i386 or Linux/i386
    processes, clear PCB_32BIT and PCB_GS32BIT bits.
  
  - Reread the fs and gs bases from the msr unconditionally, not believing
    the values in pcb_fsbase and pcb_gsbase, since usermode may reload
    segment registers, invalidating the cache.
