933 Some MIPS machines can be configured for either little or big endian
934 byte order. These modes require different kernels and a different
935 Linux distribution. In general there is one preferred byteorder for a

937 one or the other endianess.

1898 kexec is a system call that implements the ability to shutdown your
1899 current kernel, and to start another kernel. It is like a reboot
1900 but it is indepedent of the system firmware. And like a reboot
1901 you can start any kernel with it, not just Linux.
1902
1903 The name comes from the similiarity to the exec system call.
1904
1905 It is an ongoing process to be certain the hardware in a machine
1906 is properly shutdown, so do not be surprised if this code does not
1907 initially work for you. It may help to enable device hotplugging
1908 support. As of this writing the exact hardware interface is
1909 strongly in flux, so no good recommendation can be made.

1916 This kernel feature is useful for number crunching applications
1917 that may need to compute untrusted bytecode during their
1918 execution. By using pipes or other transports made available to
1919 the process as file descriptors supporting the read/write
1920 syscalls, it's possible to isolate those applications in
1921 their own address space using seccomp. Once seccomp is
1922 enabled via /proc/<pid>/seccomp, it cannot be disabled
1923 and the task is only allowed to execute a few safe syscalls
1924 defined by each seccomp mode.
1925
