787 to print messages very early in the bootup process.
789 This is useful for kernel debugging when your machine crashes very
790 early before the console code is initialized. For normal operation,
791 it is not recommended because it looks ugly on some machines and
792 doesn't cooperate with an X server. You should normally say N here,

1936 bool "Use 64-bit ELF format for building"
1937 depends on 64BIT
1938 help
1939 A 64-bit kernel is usually built using the 64-bit ELF binary object
1940 format as it's one that allows arbitrary 64-bit constructs. For
1941 kernels that are loaded within the KSEG compatibility segments the
1942 32-bit ELF format can optionally be used resulting in a somewhat
1943 smaller binary, but this option is not explicitly supported by the
1944 toolchain and since binutils 2.14 it does not even work at all.
1946 Say Y to use the 64-bit format or N to use the 32-bit one.
1948 If unsure say Y.

1957 help
1958 Select this option if you want Linux/MIPS 32-bit binary
1959 compatibility. Since all software available for Linux/MIPS is
1960 currently 32-bit you should say Y here.

1975 help
1976 Select this option if you want to run o32 binaries. These are pure
1977 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1978 existing binaries are in this format.
1980 If unsure, say Y.

1985 help
1986 Select this option if you want to run n32 binaries. These are
1987 64-bit binaries using 32-bit quantities for addressing and certain
1988 data that would normally be 64-bit. They are used in special
1989 cases.
1991 If unsure, say N.
