Shouldn't there some kind of access control here? It appears as if
anyone at all can do inx/outx. Also, I have a vague feeling that the
Linux kernel manages to support userland inx/outx without system calls -
if so, how do they do that?

Possibly with modern hardware the cost of the bus transaction dwarfs the
cost of doing a system call so perhaps it doesn't matter.
