I'm a bit disturbed about the following differences between the
implementation and this manual page:

* Unlike FreeBSD, where this `feature' is always available,
  NetBSD requires COMPAT_10 for it.  Not a great difference,
  but the manual ought to cover it.  (In this light the deprecation
  notice is far too weak.)

* Unlike FreeBSD, NetBSD requires a write-enabled file descriptor
  to /dev/io to set IOPL.  Again, not a great functional difference,
  but in this case the manual says explicitly otherwise; any
  objections to removing the read-only access for group kmem completely?

Please make sure when importing such documentation that it actually
describes the NetBSD behaviour.
