	help
	  When this is enabled, the kernel will support use of 64-bit floating
	  point registers with binaries using the O32 ABI along with the
	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
	  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.

2861 2862 2863 2864 2865 2866 2867 2868
	  Although binutils currently supports use of this flag the details
	  concerning its effect upon the O32 ABI in userland are still being
	  worked on. In order to avoid userland becoming dependant upon current
	  behaviour before the details have been finalised, this option should
	  be considered experimental and only enabled by those working upon
	  said details.

	  If unsure, say N.

	  The Extended Industry Standard Architecture (EISA) bus was

	  The EISA bus provided some of the features of the IBM MicroChannel

	  1995 when it was made obsolete by the PCI bus.
