> Теперь выпустили 4.14 с некорректными значениями частоты в /proc/cpuinfo ??? А точно не наоборот? :) _____________________ 10 days ago Commit 890da9cf0983 (Revert "x86: do not use cpufreq_quick_get() for /proc/cpuinfo "cpu MHz"") is not sufficient to restore the previous behavior of "cpu MHz" in /proc/cpuinfo on x86 due to some changes made after the commit it has reverted. To address this, make the code in question use arch_freq_get_on_cpu() which also is used by cpufreq for reporting the current frequency of CPUs and since that function doesn't really depend on cpufreq in any way, drop the CONFIG_CPU_FREQ dependency for the object file containing it. Also refactor arch_freq_get_on_cpu() somewhat to avoid IPIs and return cached values right away if it is called very often over a short time (to prevent user space from triggering IPI storms through it).
