  Log:
  Merge from FreeBSD-4, revision 1.115.2.20:
  
  	Pin 0 on the first I/O APIC is always an ExtINT pin.  Some BIOS's are
  	broken and list the type of the pin as INT rather than ExtINT in the MP
  	Table.  To workaround, force pin 0 of ioapic 0 to be ExtINT if it is of
  	type INT.  This is not a MFC as -current has very different apic code now.
  	Current's mptable parser might need a similar workaround.
  
  This fixes a bunch of Fujitsu machines; more information about the problem
  can be viewed at:

  Test equipment was kindly provided by David Rhodus!
