The cgroup_enable parameter is a Raspberry Pi kernel specific kernel parameter. Upstream based kernel do not have the parameter, and hence do not do anything. This gets rid of the following message during boot: Unknown kernel command line parameters "cgroup_enable=memory", will be passed to user space.
