[PATCH v4 0/2] nohz: fix idle accounting in NO_HZ kernels

[Hidetoshi Seto]

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.

Thanks,
H.Seto

      nohz: make updating sleep stats local
      nohz: delayed iowait accounting for nohz idle time stats
