	select CPU_JUMP_WORKAROUNDS
	help
	  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.

	  When this is enabled, the kernel will support use of 64-bit floating

	  32-bit MIPS systems this support is at the cost of increasing the
	  size and complexity of the compiled FPU emulator. Thus if you are
	  running a MIPS32 system and know that none of your userland binaries
	  will require 64-bit floating point, you may wish to reduce the size
	  of your kernel & potentially improve FP emulation performance by
	  saying N here.

	  be considered experimental and only enabled by those working upon
	  said details.
