These are more relevant:
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
# CONFIG_PREEMPT_DESKTOP is not set
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT=y
CONFIG_PREEMPT_SOFTIRQS=y
CONFIG_PREEMPT_HARDIRQS=y
CONFIG_PREEMPT_BKL=y
# CONFIG_CLASSIC_RCU is not set
CONFIG_PREEMPT_RCU=y
CONFIG_RCU_TRACE=y

The PREEMPT_RT is the main thing of the "rt" patch.
The security realtime module is realtime-lsm. Setting this here has no effect 
since it is not included in the sources but must be compiled seperately. I 
think the put that here just to tell you it is (in their estimation) 
obsolete. It still works and I do not have rlimits available.
