521 Qemu is a software emulator which among other architectures also
522 can simulate a MIPS32 4Kc system. This patch adds support for the
523 system architecture that currently is being simulated by Qemu. It
524 will eventually be removed again when Qemu has the capability to
525 simulate actual MIPS hardware platforms. More information on Qemu
526 can be found at http://www.linux-mips.org/wiki/Qemu.

1660 A 64-bit kernel is usually built using the 64-bit ELF binary object
1661 format as it's one that allows arbitrary 64-bit constructs. For
1662 kernels that are loaded within the KSEG compatibility segments the
1663 32-bit ELF format can optionally be used resulting in a somewhat
1664 smaller binary, but this option is not explicitly supported by the
1665 toolchain and since binutils 2.14 it does not even work at all.
1666
1667 Say Y to use the 64-bit format or N to use the 32-bit one.
1668
1669 If unsure say Y.

1679 Select this option if you want Linux/MIPS 32-bit binary

1681 currently 32-bit you should say Y here.
