We have used 'frozen' variable/function parameter at many places to
differentiate CPU hotplugging on suspend/resume vs sysfs removals. We now have
another variable cpufreq_suspended which can be used in these cases and hence we
can get rid of all those variables or function parameters.
freq table is not per CPU but per policy and so it makes more sense to keep it
within struct cpufreq_policy instead of a per-cpu variable.
This patch does it. Over that there is no need to set policy-freq_table to NULL
in -exit(), as policy structure is going to be freed soon.

Apart from the other patches, here are few minor cleanups for cpufreq core and
drivers. The first two removes per-cpu cpufreq_show_table variable and moves
that information in struct cpufreq_policy. And the last one removes unnecessary
frozen variable/parameters.

Hi,
Sometimes users might want to see time information along with the

In this patchset, I added such feature using sample-time. When the
