1633           Select this option if you want to run n32 binaries.  These are
1634           64-bit binaries using 32-bit quantities for addressing and certain
1635           data that would normally be 64-bit.  They are used in special
1636           cases.

1649           This kernel feature is useful for number crunching applications
1650           that may need to compute untrusted bytecode during their
1651           execution. By using pipes or other transports made available to
1652           the process as file descriptors supporting the read/write
1653           syscalls, it's possible to isolate those applications in
1654           their own address space using seccomp. Once seccomp is
1655           enabled via /proc/<pid>/seccomp, it cannot be disabled
1656           and the task is only allowed to execute a few safe syscalls
1657           defined by each seccomp mode.

1659           If unsure, say Y. Only embedded should say N here.
