** Description changed:
+ [SRU Justification]
+
+ [Impact]
+ Intel RAPL (running average power limit) driver doesn't support Comet
+ Lake platforms.
+
+ [Fix]
+ Two commits from linux-next tree to be SRU-ed:
+ * commit cae478114fbe ("powercap/intel_rapl: add support for CometLake
Mobile")
+ * commit f84fdcbc8ec0 ("powercap/intel_rapl: add support for Cometlake
+ desktop")
+
+ [Test Case]
+ 1. Boot prebuilt kernel from ppa:vicamo/ppa-1847454
+ 2. Check if /sys/devices/virtual/powercap/intel-rapl is created and
+ populated.
+
+ [Regression Potential]
+ Low. This affects only platforms with specific CPU models, which have no
+ intel_rapl support currently.
