SYNOPSIS

10                                                       i2o_msg_in_to_virt(struct i2o_controller * c,
11                                                       u32 m);

DESCRIPTION

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