| |
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 : commit fb5153d05a7d ("powerpc: powernv: Implement ppc_md.get_proc_freq()") Cc: stable@vger.kernel.org
