Moving the files is good, but I don't see a reason to make the cbe_cpufreq.h
header globally visible in include/linux/. Isn't it just used by as the
interface between ppc_cbe_cpufreq_pmi.c  and ppc_cbe_cpufreq.c?

When i moved it initially i thought it is also used by
arch/powerpc/platforms/cell/cpufreq_spudemand.c and hence moved it
to include/linux and never realized i am wrong..

Here is the fixup (And attached complete patch: original+fixup for Rafael
to apply):

Compile tested only.

Hi Rafael,

Its been more than 2 months now that this patch was first posted.
And the response from Maintainers isn't so great, irrespective of
how many times I pinged them.

This is what I think:
- It looked functionally correct to Benjamin but he wanted somebody
to actually test it.
- Arnd gave his Ack (So it looked functionally correct to him too)
- We can probably push this into linux-next now and see if somebody
complains of any breakage it has done. If not we can get it pushed for
3.11.
