+			(Speculative Store Bypass vulnerability)
+
+			Certain CPUs are vulnerable to an exploit against a
+			a common industry wide performance optimization known
+			as "Speculative Store Bypass" in which recent stores
+			to the same memory location may not be observed by
+			later loads during speculative execution. The idea
+			is that such stores are unlikely and that they can
+			be detected prior to instruction retirement at the
+			end of a particular speculation execution window.
+
+			In vulnerable processors, the speculatively forwarded
+			store can be used in a cache side channel attack, for
+			example to read memory to which the attacker does not
+			directly have access (e.g. inside sandboxed code).
+
+			This parameter controls whether the Speculative Store
+			Bypass optimization is used.
+
+			on     - Unconditionally disable Speculative Store Bypass
+			off    - Unconditionally enable Speculative Store Bypass
+			auto   - Kernel detects whether the CPU model contains an
+				 implementation of Speculative Store Bypass and
+				 picks the most appropriate mitigation
+
+			Not specifying this option is equivalent to
+			spec_store_bypass_disable=auto.
