The ProcFS is an utter mess currently, so let's start move things that are not related to processes-info. To ensure it's done in a sane manner, we start by duplicating all /proc/ global nodes to the /sys/kernel/ directory, then we will move Userland to use the new directory so the old directory nodes can be removed from the /proc directory.
