No, you misunderstood my intention. Of course your branch is a much
stricter one with all new cpufreq commits reverted.

I was just trying to point out commits which came after 3.13.8, in case even
your branch (3.13.8 along with cpufreq reverts) ends up passing his tests. In
that case we'll have to narrow down *within* the commits between v3.13.8 and
v3.14.1, no? My list was to help with that.

Right, sorry, I was doing a diff between 3.13.8 and 3.15-rc8 (based on his
first report) by mistake. Ignore these 2 commits, they are recent. But the
other ones I listed came in between v3.13.8 and v3.14, so they might be worth
trying.
