  "message": "x86: CPU: Fix up \"cpu MHz\" in /proc/cpuinfo\n\nCommit 890da9cf0983 (Revert \"x86: do not use cpufreq_quick_get() for\n/proc/cpuinfo \"cpu MHz\"\") is not sufficient to restore the previous\nbehavior of \"cpu MHz\" in /proc/cpuinfo on x86 due to some changes\nmade after the commit it has reverted.\n\nTo address this, make the code in question use arch_freq_get_on_cpu()\nwhich also is used by cpufreq for reporting the current frequency of\nCPUs and since that function doesn\u0027t really depend on cpufreq in any\nway, drop the CONFIG_CPU_FREQ dependency for the object file\ncontaining it.\n\nAlso refactor arch_freq_get_on_cpu() somewhat to avoid IPIs and\nreturn cached values right away if it is called very often over a\nshort time (to prevent user space from triggering IPI storms through\nit).\n\nFixes: 890da9cf0983 (Revert \"x86: do not use cpufreq_quick_get() for /proc/cpuinfo \"cpu MHz\"\")\nCc: stable@kernel.org   # 4.13 - together with 890da9cf0983\nSigned-off-by: Rafael J.
