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

1926 bool "Support for large 64-bit configurations"
1927 depends on CPU_R10000 && 64BIT
1928 help
1929 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1930 previous 64-bit processors which only supported 40 bit / 1TB. If you
1931 need processes of more than 1TB virtual address space, say Y here.
1932 This will result in additional memory usage, so it is not
1933 recommended for normal users.

1935 config KEXEC
1936 bool "Kexec system call (EXPERIMENTAL)"
1937 depends on EXPERIMENTAL
1938 help
1939 kexec is a system call that implements the ability to shutdown your
1940 current kernel, and to start another kernel. It is like a reboot
1941 but it is independent of the system firmware. And like a reboot
1942 you can start any kernel with it, not just Linux.
1943
1944 The name comes from the similarity to the exec system call.
1945
1946 It is an ongoing process to be certain the hardware in a machine
1947 is properly shutdown, so do not be surprised if this code does not
1948 initially work for you. It may help to enable device hotplugging
1949 support. As of this writing the exact hardware interface is
1950 strongly in flux, so no good recommendation can be made.

1955 default y
1956 help
1957 This kernel feature is useful for number crunching applications
1958 that may need to compute untrusted bytecode during their
1959 execution. By using pipes or other transports made available to
1960 the process as file descriptors supporting the read/write
1961 syscalls, it's possible to isolate those applications in
1962 their own address space using seccomp. Once seccomp is
1963 enabled via /proc/<pid>/seccomp, it cannot be disabled
1964 and the task is only allowed to execute a few safe syscalls
1965 defined by each seccomp mode.
1966
1967 If unsure, say Y. Only embedded should say N here.

2032 The Extended Industry Standard Architecture (EISA) bus was
2033 developed as an open alternative to the IBM MicroChannel bus.
2034
2035 The EISA bus provided some of the features of the IBM MicroChannel
2036 bus while maintaining backward compatibility with cards made for
2037 the older ISA bus. The EISA bus saw limited use between 1988 and
2038 1995 when it was made obsolete by the PCI bus.
