861 Networks. It builds a kernel that dynamically determines the Octeon
862 CPU type and supports all known board reference implementations.

2673 help
2674 When this is enabled, the kernel will support use of 64-bit floating
2675 point registers with binaries using the O32 ABI along with the
2676 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2677 32-bit MIPS systems this support is at the cost of increasing the
2678 size and complexity of the compiled FPU emulator. Thus if you are
2679 running a MIPS32 system and know that none of your userland binaries
2680 will require 64-bit floating point, you may wish to reduce the size
2681 of your kernel & potentially improve FP emulation performance by
2682 saying N here.

2684 Although binutils currently supports use of this flag the details
2685 concerning its effect upon the O32 ABI in userland are still being
2686 worked on. In order to avoid userland becoming dependant upon current
2687 behaviour before the details have been finalised, this option should
2688 be considered experimental and only enabled by those working upon
2689 said details.
2690
2691 If unsure, say N.

2820 bus while maintaining backward compatibility with cards made for
2821 the older ISA bus. The EISA bus saw limited use between 1988 and
