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-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9565e1e078329da7c92dd6812685bf8a2dd9b8e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.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.
