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

1946 help
1947 A 64-bit kernel is usually built using the 64-bit ELF binary object
1948 format as it's one that allows arbitrary 64-bit constructs. For
1949 kernels that are loaded within the KSEG compatibility segments the
1950 32-bit ELF format can optionally be used resulting in a somewhat
1951 smaller binary, but this option is not explicitly supported by the
1952 toolchain and since binutils 2.14 it does not even work at all.
1954 Say Y to use the 64-bit format or N to use the 32-bit one.
1956 If unsure say Y.

1966 Select this option if you want Linux/MIPS 32-bit binary
1967 compatibility. Since all software available for Linux/MIPS is
1968 currently 32-bit you should say Y here.

1995 64-bit binaries using 32-bit quantities for addressing and certain
1996 data that would normally be 64-bit. They are used in special
1997 cases.
