Currently, loops_per_jiffy is being calculated twice for

Double adjustment leads to incorrect value being assigned to
loops_per_jiffy. This manifests as incorrect BogoMIPS in
"cat /proc/cpuinfo".

The value of loops_per_jiffy needs to be calculated only
when CONFIG_SMP is true. It is the core change included
in this patch.

The patch also leverages the definition of for_each_cpu()
with and without CONFIG_SMP to consolidate the mechanism
to call cpufreq_notify_transition().

NAK. This patch again doesn't make sense considering your issue.
Also jiffies should not be undated before changing the freq.
If the set_rate failed for some reason then you will have wrong
jiffies value.

I understand your issue now. The code for global lpj updation
should have been checking smp_on_up() instead of is_smp().
That one line change is enough. I will post a patch on
the same once I reach to office.
