Most of the CPUFreq drivers do similar things in .exit() and .verify() routines
and .attr. So its better if we have generic routines for them which can be used
by cpufreq drivers then.
This patchset first fixes all existing drivers to do
cpufreq_frequency_table_put_attr() corresponding to
cpufreq_frequency_table_get_attr() and then create generic routines which will
be used by most of the cpufreq drivers.
This is rebased on Rafael's bleeding edge + some more cleanup work that I posted
earlier:
https://lkml.org/lkml/2013/8/8/263
This patchset and its dependencies are pushed here:
https://git.linaro.org/gitweb?p=people/vireshk/linux.git;a=shortlog;h=refs/heads/for-v3.13
@Rafael: You would be very happy to see the changelog :)

This one is sent by mistake.. It isn't ready yet and will be sent separately
later. :(
