1981 config KEXEC
1982 bool "Kexec system call (EXPERIMENTAL)"
1983 depends on EXPERIMENTAL
1984 help
1985 kexec is a system call that implements the ability to shutdown your
1986 current kernel, and to start another kernel. It is like a reboot
1987 but it is independent of the system firmware. And like a reboot
1988 you can start any kernel with it, not just Linux.
1990 The name comes from the similarity to the exec system call.
1992 It is an ongoing process to be certain the hardware in a machine
1993 is properly shutdown, so do not be surprised if this code does not
1994 initially work for you. It may help to enable device hotplugging
1995 support. As of this writing the exact hardware interface is
1996 strongly in flux, so no good recommendation can be made.

2001 default y
2002 help
2003 This kernel feature is useful for number crunching applications
2004 that may need to compute untrusted bytecode during their
2005 execution. By using pipes or other transports made available to
2006 the process as file descriptors supporting the read/write
2007 syscalls, it's possible to isolate those applications in
2008 their own address space using seccomp. Once seccomp is
2009 enabled via /proc/<pid>/seccomp, it cannot be disabled
2010 and the task is only allowed to execute a few safe syscalls
2011 defined by each seccomp mode.
2013 If unsure, say Y. Only embedded should say N here.

2074 The Extended Industry Standard Architecture (EISA) bus was
2075 developed as an open alternative to the IBM MicroChannel bus.
2077 The EISA bus provided some of the features of the IBM MicroChannel
2078 bus while maintaining backward compatibility with cards made for
2079 the older ISA bus. The EISA bus saw limited use between 1988 and
2080 1995 when it was made obsolete by the PCI bus.
