816 This is useful for kernel debugging when your machine crashes very
817 early before the console code is initialized. For normal operation,
818 it is not recommended because it looks ugly on some machines and

1911 MIPS R10000 does support a 44 bit / 16TB address space as opposed to

1920 help
1921 kexec is a system call that implements the ability to shutdown your
1922 current kernel, and to start another kernel. It is like a reboot
1923 but it is independent of the system firmware. And like a reboot
1924 you can start any kernel with it, not just Linux.
1925
1926 The name comes from the similarity to the exec system call.
1927
1928 It is an ongoing process to be certain the hardware in a machine
1929 is properly shutdown, so do not be surprised if this code does not
1930 initially work for you. It may help to enable device hotplugging
1931 support. As of this writing the exact hardware interface is
1932 strongly in flux, so no good recommendation can be made.

1938 help
1939 This kernel feature is useful for number crunching applications
1940 that may need to compute untrusted bytecode during their
1941 execution. By using pipes or other transports made available to
1942 the process as file descriptors supporting the read/write
1943 syscalls, it's possible to isolate those applications in
1944 their own address space using seccomp. Once seccomp is
1945 enabled via /proc/<pid>/seccomp, it cannot be disabled
1946 and the task is only allowed to execute a few safe syscalls
1947 defined by each seccomp mode.
1948

2003 The Extended Industry Standard Architecture (EISA) bus was
2004 developed as an open alternative to the IBM MicroChannel bus.

2006 The EISA bus provided some of the features of the IBM MicroChannel
2007 bus while maintaining backward compatibility with cards made for
2008 the older ISA bus. The EISA bus saw limited use between 1988 and
2009 1995 when it was made obsolete by the PCI bus.
