+
+ If you say N here, the kernel will run on uni- and multiprocessor

+ will run faster if you say N here.

+ This kernel feature is useful for number crunching applications

+ syscalls, it's possible to isolate those applications in
+ their own address space using seccomp. Once seccomp is

+config SERIAL_CONSOLE
+ bool

+ ---help---
+ If you say Y here, it will be possible to use a serial port as the

+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as

+ your boot loader (silo) about how to pass options to the kernel at
+ boot time.)
