3.16.54-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Shriya <shriyak@xxxxxxxxxxxxxxxxxx>
commit cd77b5ce208c153260ed7882d8910f2395bfaabd upstream.
The call to /proc/cpuinfo in turn calls cpufreq_quick_get() which
returns the last frequency requested by the kernel, but may not
reflect the actual frequency the processor is running at. This patch
makes a call to cpufreq_get() instead which returns the current
frequency reported by the hardware.
Fixes: fb5153d05a7d ("powerpc: powernv: Implement ppc_md.get_proc_freq()")
