776 This option enables special console drivers which allow the kernel
777 to print messages very early in the bootup process.
778
779 This is useful for kernel debugging when your machine crashes very
780 early before the console code is initialized. For normal operation,
781 it is not recommended because it looks ugly on some machines and
782 doesn't cooperate with an X server. You should normally say N here,

833 byte order. These modes require different kernels and a different

1927 help
1928 kexec is a system call that implements the ability to shutdown your
1929 current kernel, and to start another kernel. It is like a reboot
1930 but it is independent of the system firmware. And like a reboot
1931 you can start any kernel with it, not just Linux.
1932
1933 The name comes from the similarity to the exec system call.
1934
1935 It is an ongoing process to be certain the hardware in a machine
1936 is properly shutdown, so do not be surprised if this code does not
1937 initially work for you. It may help to enable device hotplugging
1938 support. As of this writing the exact hardware interface is
1939 strongly in flux, so no good recommendation can be made.

1945 help
1946 This kernel feature is useful for number crunching applications
1947 that may need to compute untrusted bytecode during their
1948 execution. By using pipes or other transports made available to
1949 the process as file descriptors supporting the read/write
1950 syscalls, it's possible to isolate those applications in
1951 their own address space using seccomp. Once seccomp is
1952 enabled via /proc/<pid>/seccomp, it cannot be disabled
1953 and the task is only allowed to execute a few safe syscalls
1954 defined by each seccomp mode.
