NAME

i2o_msg_out_to_virt - Turn an I2O message to a virtual address

SYNOPSIS

struct i2o_message * i2o_msg_out_to_virt(struct i2o_controller * c,
                                         u32 m);

ARGUMENTS

c
controller
m
message engine value

DESCRIPTION

Turn a receive 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 sender side
messages as they are ioremap objects provided by the I2O controller.
