Odd Kconfig output..

[Valdis . Kletnieks]

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'?
