Saw this while doing a 'make oldconfig' moving from -mmotm0827 to -mmotm0903:
RCU Implementation
> 1. Tree-based hierarchical RCU (TREE_RCU)
2. Preemptable tree-based hierarchical RCU (TREE_PREEMPT_RCU) (NEW)
choice[1-2]: ?
There is no help available for this kernel option.
Prompt: RCU Implementation
Defined at init/Kconfig:329
Location:
-> General setup
-> RCU Subsystem
Selected by: m [=m]
Where did that 'Selected by:' come from? Or is that just an artifact of
the way Kconfig implements 'choice'?

Many of the architectures use a "select" clause for RCU, usually
selecting CLASSIC_RCU. Could that be the issue?
Thanx, Paul
