I don't really care about malicious user-mode applications being able to take a peek at kernel memory on my desktop machine, because there are effectively two users: me, who often becomes root locally and remotely, and root. I do care about random websites being able to do the same (obviously). Due to "Linux security properties" any random user-mode application is me and therefore already root and does not require an exploit to read kernel memory. The user-root-distinction is all but the thinnest of veils on a desktop Linux.
