NAME
       i2o_msg_out_to_virt - Turn an I2O message to a virtual address

SYNOPSIS
       struct i2o_message * i2o_msg_out_to_virt(struct i2o_controller * c, u32 m);

ARGUMENTS
       c
	   controller

       m
	   message engine value

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