From: Greg Kroah-Hartman <gre...@suse.de>
In the interest of keeping userspace from having to create new root
filesystems all the time, let's follow the lead of the other in-kernel
filesystems and provide a proper mount point for it in sysfs.
For selinuxfs, this mount point should be in /sys/fs/selinux/

Resend, due to lack of response.
Note, patch is untested, I don't have any selinux-based machines here,
sorry.
