-   Modern devices hopefully are sane enough not to put any performance
-   critical registers in i/o space.
-
-   On the first call to ioperm() or iopl(), the entire (E)ISA port
-   space is mapped into the virtual address space at address io.base.
-   mprotect() calls are then used to enable/disable access to ports.
-   Per 4KB page, there are 4 I/O ports.  */
