  Work around a firmware bug in the HP rx2660, where in ACPI an I/O port
  is really a memory mapped I/O address. The bug is in the GAS that
  describes the address and in particular the SpaceId field. The field
  should not say the address is an I/O port when it clearly is not.
  With an additional check for the IA64_BUS_SPACE_IO case in the bus
  access functions, and the fact that I/O ports pretty much not used
  in general on ia64, make the calculation of the I/O port address a
  function. This avoids inlining the work-around into every driver,
  and also helps reduce overall code bloat.
