	  Select this option if you want to run o32 binaries.  These are pure
	  32-bit binaries as used by the 32-bit Linux/MIPS port.  Most of
	  existing binaries are in this format.

	  If unsure, say Y.

config MIPS32_N32
	bool "Kernel support for n32 binaries"
	depends on MIPS32_COMPAT
	help
	  Select this option if you want to run n32 binaries.  These are
	  64-bit binaries using 32-bit quantities for addressing and certain
	  data that would normally be 64-bit.  They are used in special
	  cases.

	  If unsure, say N.
