From: Shriya Date: Fri, 13 Oct 2017 04:36:41 +0000 (+0530) Subject: powerpc/powernv/cpufreq: Fix the frequency read by /proc/cpuinfo X-Git-Tag: v3.18.89~26 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b4c9f0c128359d0b20c6be9ea1c125dda492417a;p=thirdparty%2Fkernel%2Fstable.git powerpc/powernv/cpufreq: Fix the frequency read by /proc/cpuinfo [ Upstream commit cd77b5ce208c153260ed7882d8910f2395bfaabd ] 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.
