The fix patch in
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=29e9bf1841e4f9df13b4992a716fece7087dd237
does record the events in
/sys/devices/system/cpu/cpu#/thermal_throttle/core_power_limit_count or
package_power_limit_count

Tools can monitor the counters to know the power limit notification events.

What the fix patch doesn't show is the message in log_buf and mce log which are
annoying according to user's feedback.
