CONFIG_BUILD_ELF64: Use 64-bit ELF format for building

General informations

The Linux kernel configuration item CONFIG_BUILD_ELF64:

Help text

A 64-bit kernel is usually built using the 64-bit ELF binary object format as it's one that allows arbitrary 64-bit constructs. For kernels that are loaded within the KSEG compatibility segments the 32-bit ELF format can optionally be used resulting in a somewhat smaller binary, but this option is not explicitly supported by the toolchain and since binutils 2.14 it does not even work at all.

Say Y to use the 64-bit format or N to use the 32-bit one.

If unsure say Y.
