211 The User-Mode Linux port can provide support for IO Memory
212 emulation with this option. This allows a host file to be
213 specified as an I/O region on the kernel command line. That file
214 will be mapped into UML's kernel address space where a driver can
215 locate it and do whatever it wants with the memory, including
216 providing an interface to it for UML processes to use.

221 If you'd like to be able to provide a simulated IO port space for
222 User-Mode Linux processes, say Y. If unsure, say N.
