  1571. A 64-bit kernel is usually built using the 64-bit ELF binary object
  1572. format as it's one that allows arbitrary 64-bit constructs. For
  1573. kernels that are loaded within the KSEG compatibility segments the
  1574. 32-bit ELF format can optionally be used resulting in a somewhat
  1575. smaller binary, but this option is not explicitly supported by the
  1576. toolchain and since binutils 2.14 it does not even work at all.
  1577. Say Y to use the 64-bit format or N to use the 32-bit one.
  1578. If unsure say Y.
