Adding help text would be... helpful.   :)

The net result in this case was the addition of a completely-unexplained 
Kconfig option late in 2.6.31-rc.

Maybe the x86 maintainers could help see that they don't push 
unexplained Kconfig options upstream -- particularly ones we are asked 
to enable by default?
