This works fine for cpu{1,2,3} after
Revert "cpufreq: fix garbage kobjects on
errors during suspend/resume"
This reverts commit
2167e2399dc5e69c62db56d933e9c8cbe107620a.
is applied to v3.13-rc3. There is no file
cpu0/online.
I can check the behaviour of v3.13-rc3 itself only tomorrow,
since I am travelling.

Martin

I took the Bjorn's patch for 3.13 and this one I can queued up for 3.14,
but for that I guess it should contain a revert of the change made by the
Bjorn's patch.
This patch causes a s3 regression. Cc:Martin Ziegler

Hmm.. With Bjorn's patch applied, the cpufreq hotplug callback should become
identical to what happens during regular CPU hotplug. So is regular CPU
hotplug also failing for you, Martin?
You can do CPU hotplug by:
CPU offline:
echo 0 > /sys/devices/system/cpu/cpu<num>/online
CPU online:
echo 1 > /sys/devices/system/cpu/cpu<num>/online
Bjorn's patch looks pretty innocuous to me.. I couldn't catch any obvious
bug looking at the code. So answer to the above question should help us dig
deeper.
