+	noxsaveopt	[X86] Disables xsaveopt used in saving x86 extended
+			register states. The kernel will fall back to use
+			xsave to save the states. By using this parameter,

+			restoring x86 extended register state in compacted
+			form of xsave area. The kernel will fall back to use
+			xsaveopt and xrstor to save and restore the states
+			in standard form of xsave area. By using this

+			memory on xsaves enabled systems.
