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

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

199 Say N, unless you absolutely know what you are doing.
