Log Message:
gpioirq(4) version 2

This update makes this driver more than just an example and allows for:

o More than one pin to be attached to a gpioirq instance.  That is,
  the mask parameter can be greater than 0x01 now.

o A /dev/gpioirqN device that allows GPIO pin interrupts to be
  transported into userland.  This is a device that can be opened for
  reading with a simple fixed output indicating the device unit, pin
  number and current pin state.

This update was used as part of a physical intrusion detection system
where multiple switches (i.e. window magnetic reed switches and etc.)
are tied to a bunch of GPIO inputs with userland software that reacts
to the pins changing state.
