- Extract the IODEV_PIO interface from ia64 and make it MI.
  In the end, it does help fixing /dev/io usage from multithreaded
  processes.
- On i386 and amd64 the old behaviour is kept but multithreaded
  processes must use the new interface in order to work well.
- Support for the other architectures is greatly improved, where
  necessary, by the necessity to define very small things now.

Manpage update will happen shortly.
