Hi Fengguang,
Sorry, I can't reproduce your issue.
I clone linux-next repository then "git checkout remotes/origin/akpm". I can compile kernel successfully with your .config files without any errors or warnings. I use gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3.
With the best regards,
Vyacheslav Dubeyko.
