+ help
+ This option enables special console drivers which allow the
kernel
+ to print messages very early in the bootup process.
+
+ This is useful for kernel debugging when your machine crashes
very
+ early before the console code is initialized. For normal
operation,
+ it is not recommended because it looks ugly on some machines and
+ doesn't cooperate with an X server. You should normally say N
here,
+ unless you want to debug such a crash.

+ depends on EXPERIMENTAL
+ help
+ kexec is a system call that implements the ability to shutdown
your
+ current kernel, and to start another kernel. It is like a
reboot
+ but it is independent of the system firmware. And like a
reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
+ is properly shutdown, so do not be surprised if this code does
not
+ initially work for you. It may help to enable device
hotplugging
+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.
+
+config SECCOMP
+ bool "Enable seccomp to safely compute untrusted bytecode"
+ depends on PROC_FS
+ default y
+ help
+ 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.
