This isn't unreasonable but there are drivers with userspace helpers that
use iopl/ioperm type functionality where you should be doing a SELECT of
X86_IOPORT. The one that comes to mind is the uvesa driver. From a quick
scan it may these days be the only mainstream one that needs the

On the vast majority of modern systems, no processes will use the
userspsace IO syscalls, iopl and ioperm. Add a new config option,
CONFIG_X86_IOPORT, to support configuring them out of the kernel
entirely. Most current systems do not run programs using these
syscalls, so X86_IOPORT does not
