and want to use the 64 bit addressing mode.

Select this option if you want to enable your system kernel to
handle system-calls from ELF binaries for 31 bit ESA. This option
(and some other stuff like libraries and such) is needed for
executing 31 bit applications. It is safe to say "Y".

This allows you to run 32-bit Linux/ELF binaries on your zSeries
in 64 bit mode. Everybody wants this; say Y.

Select this to build a 31 bit kernel that works
on all S/390 and zSeries machines.
