[rtl] I/O ports beyond 0x3FF

[Alexandre Apóstolo]

In order to obtain access to the I/O port beyond 0x3FF I belive I have to call the "iopl" Linux funcion. I am able to compile the modules, but I can't load them into the kernel.   Can anyone explain me why can´t I load any RTLinux modules containig th "iopl" Linux function?
