The generic config has CONFIG_RCU_EXPERT=y, which exposes CONFIG_RCU_FANOUT. This is set to 32 in the generic config, but the default for 64bit kernels is 64. This causes a warning during boot:
[ 0.000000] rcu: CONFIG_RCU_FANOUT set to non-default value of 32. Set CONFIG_RCU_FANOUT=64 in kernel configs of 64bit targets, unless the target config has disabled CONFIG_RCU_EXPERT.
