-/* I/O port access on the ARM is something of a fiction.  What we do is to
-   map an appropriate area of /dev/mem into user space so that a program
-   can blast away at the hardware in such a way as to generate I/O cycles
-   on the bus.  To insulate user code from dependencies on particular
-   hardware we don't allow calls to inb() and friends to be inlined, but
-   force them to come through code in here every time.  Performance-critical
-   registers tend to be memory mapped these days so this should be no big
-   problem.  */

-/* Once upon a time this file used mprotect to enable and disable
-   access to particular areas of I/O space.  Unfortunately the
-   mprotect syscall also has the side effect of enabling caching for
-   the area affected (this is a kernel limitation).  So we now just
-   enable all the ports all of the time.  */
