+          Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
+          require workarounds.  Without workarounds the system may hang
+          unexpectedly.  For more information please refer to the gas
+          -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
+
+          Loongson 2F03 and later have fixed these issues and no workarounds
+          are needed.  The workarounds have no significant side effect on them
+          but may decrease the performance of the system so this option should
+          be disabled unless the kernel is intended to be run on 2F01 or 2F02
+          systems.
+
+          If unsure, please say Y.
