DESCRIPTION

20       Turn a receive message from an I2O controller bus address into a Linux
21       virtual address. The shared page frame is a linear block so we simply
22       have to shift the offset. This function does not work for sender side
23       messages as they are ioremap objects provided by the I2O controller.
