Subject: config RCU_EQS_DEBUG

Hi Paul,

You just introduced a Linux kernel configuration option named
RCU_EQS_DEBUG. Its short description is "Use this when adding any sort
of NO_HZ support to your arch".

I'm afraid this is a bad way to briefly explain what the option
actually does (which is what the short description is for.) A sentence
like "use this when adding any sort of NO_HZ support to your arch"
should go in the help text, not the short description. The short
description should be something like along the lines of "Enable
consistency checks for RCU", for example.

Additionally I see some inconsistency in the fact that this option
defaults to n but the help text says "Say Y if you are unsure". BTW,
option RCU_CPU_STALL_INFO is equally inconsistent with a default y and
"say N if you are unsure" in the help text.
