Enable cpuset cgroup subsystem on RPi 2/3

I would like to point out one possible omission in the instructions to setup rt-preempt linux image on RPi2/RPi3 (http://www.machinekit.io/docs/getting-started/install-rt-kernel-RPi2/).

By default Raspbian (at least current jessie) disables cpuset cgroup subsystem and therefore you will not be able to mount cpuset filesystem. I would suggest adding cgroup_enable=cpuset to /boot/cmdline.txt

Sorry, just found this.

Can I ask you to either submit a PR if you have a github account and are familiar with that, or to do it from the web site, by pressing 'Edit This Page' from within the relevant page and make the necessary amendments / additions. The latter will automatically create a PR for you.
