+// Package mitigate provides libraries for the mitigate command. The
+// mitigate command mitigates side channel attacks such as MDS. Mitigate
+// shuts down CPUs via /sys/devices/system/cpu/cpu{N}/online. In addition,
+// the mitigate also handles computing available CPU in kubernetes kube_config
+// files.
