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.
