[$] Killing off /dev/kmem

The recent proposalfrom David Hildenbrand to remove support for the /dev/kmem specialfile has not sparked a lot of discussion. Perhaps that is because today'syoungsters, lacking an understanding of history, may be wonderingwhat that file is in the first place and, thus, be unclear on why it maymatter. Chances are that /dev/kmem will not be missed, but inpassing it takes away a venerable part of the Unix kernel interface.
