see the Linux/MIPS FAQ on <http://www.linux-mips.org/> and the
DECstation porting pages on <http://decstation.unix-ag.org/>.
If you have one of the following DECstation Models you definitely
want to choose R4xx0 for the CPU Type:
DECstation 5000/50
DECstation 5000/150
DECstation 5000/260

Some MIPS machines can be configured for either little or big endian
byte order. These modes require different kernels and a different
Linux distribution. In general there is one prefered byteorder for a
particular system but some systems are just as commonly used in the
one or the other endianess.

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