Modern devices hopefully are sane enough not to put any performance
critical registers in i/o space.
On the first call to ioperm() or _sethae(), 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
