182 Mmiotrace traces Memory Mapped I/O access and is meant for
183 debugging and reverse engineering. It is called from the ioremap
184 implementation and works via page faults. Tracing is disabled by
185 default and can be enabled at run-time.

194 This is a dumb module for testing mmiotrace. It is very dangerous
195 as it will write garbage to IO memory starting at a given address.
196 However, it should be safe to use on e.g. unused portion of VRAM.
