i2o_msg_in_to_virt - Turn an I2O message to a virtual address

2. SYNOPSIS

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

3. ARGUMENTS

c
    controller

m
    message engine value

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.
