    sys/i386/include     pcb.h 
  Log:
  MFC: stop vm86bios calls from panicing the system or corrupting the first
  4 bytes of random pages.  Rename the vm86 data structure in the pcb from
  __pcb_spare[] to pcb_vm86[] to hopefully avoid this happening again.
  
  This was broken in September 2003, and the bug is present in 5.2 and later.
