+	  New Loongson 3 CPU (since Loongson-3A R2, as opposed to Loongson-3A
+	  R1, Loongson-3B R1 and Loongson-3B R2) has many enhancements, such as
+	  FTLB, L1-VCache, EI/DI/Wait/Prefetch instruction, DSP/DSPv2 ASE, User
+	  Local register, Read-Inhibit/Execute-Inhibit, SFB (Store Fill Buffer),
+	  Fast TLB refill support, etc.
+
+	  This option enable those enhancements which are not probed at run
+	  time. If you want a generic kernel to run on all Loongson 3 machines,
+	  please say 'N' here. If you want a high-performance kernel to run on
+	  new Loongson 3 machines only, please say 'Y' here.
