Let's start a discussion if /dev/kmem is worth keeping around and fixing/maintaining or if we should just remove it now for good.
More details / findings in patch #1. Patch #2 and #3 perform minor cleanups based on removed /dev/kmem support. Only compile-tested on x86-64 -- good enough for discussing the general topic (RFC).
