NAME
i2o_msg_in_to_virt - Turn an I2O message to a virtual addressSYNOPSIS
- 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.
