+Subject: cpupower: Fix checks for CPU existence
+Forwarded: https://marc.info/?l=linux-pm&m=149248268214265
+
+Calls to cpufreq_cpu_exists(cpu) were converted to
+cpupower_is_cpu_online(cpu) when libcpupower was introduced and the
+former function was deleted.  However, cpupower_is_cpu_online() does
+not distinguish physically absent and offline CPUs, and does not set
+errno.
+
+cpufreq-set has already been fixed (commit c25badc9ceb6).
+
+In cpufreq-bench, which prints an error message for offline CPUs,
+properly distinguish and report the zero and negative cases.
+
+Fixes: ac5a181d065d ("cpupower: Add cpuidle parts into library")
+Fixes: 53d1cd6b125f ("cpupowerutils: bench - Fix cpu online check")

+[carnil: Update/Refresh patch for 4.14.17: The issue with the
+incorrect check has been fixed with upstream commit 53d1cd6b125f.
+Keep in the patch the distinction and report for the zero and
+negative cases.]
