I2O_MSG_IN_TO_VIRT(9)					       Message-based devices					     I2O_MSG_IN_TO_VIRT(9)

NAME
       i2o_msg_in_to_virt - Turn an I2O message to a virtual address

SYNOPSIS
       struct i2o_message __iomem * i2o_msg_in_to_virt(struct i2o_controller * c, u32 m);

ARGUMENTS
       c
	   controller

       m
	   message engine value

DESCRIPTION
       Turn a send 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 receive side messages as they are kmalloc objects in a different pool.
