Sorry: I dont build kernels for Musix, but I used to

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_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.
