** Description changed:
+ [Impact]
+ We have Hisilicon PMU modules built-in and they can not be unloaded. There is
no way to replace with a updated module unless we build it as module.
+
+ [Test Plan]
+ `lsmod | grep hisi_uncore` shall see 4 modules loaded and they can be
unloaded.
+
+ [Regression Risk]
+ CONFIG_HISI_PMU shall be only affected Hisilicon platforms that HISI0213 is
found in ACPI tables. We shall have perf test run on these platforms and others
have lowest risk.
+
+ =================================
