			on   - unconditionally enable

			auto - kernel detects whether your CPU model is

			       vulnerable



			Selecting 'on' will, and 'auto' may, choose a

			mitigation method at run time according to the

			CPU, the available microcode, the setting of the

			CONFIG_RETPOLINE configuration option, and the

			compiler with which the kernel was built.



			Specific mitigations can also be selected manually:



			retpoline	  - replace indirect branches

			retpoline,generic - google's original retpoline

			retpoline,amd     - AMD-specific minimal thunk



			Not specifying this option is equivalent to

			spectre_v2=auto.
