Hi all, This patch set (rebased on v3.15-rc1) is my 4th try to fix an issue that idle/iowait of /proc/stat can go backward. Originally reported by Tetsuo and Fernando at last year, Mar 2013. This v4 updates v3's approach, and adds description/comments to make patch's intent to be clear (I hope so). Of course still reviews are welcome.
