This is incredibly ugly. Why should the generic fs/Kconfig know about some 
random odd architecture detail like PPC_BOOK3S_64?

I merged it, and noticed this because Super-H caused clashes by cleaning 
up. I would suggest PowerPC do the same.

This patch is not signed-off, nor do I want any credit. But if it works on 
ppc, please send me something like this back.
