Making CGROUP related configs be a sub-menu.
This patch make CGROUP related configs be a sub-menu and makes 1st level
configs of "General Setup" shorter.
including following additional changes
- add help comment about CGROUPS and GROUP_SCHED.
- moved MM_OWNER config to the bottom.
(for good indent in menuconfig)
