	  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.
