789 you can start any kernel with it, not just Linux.
791 The name comes from the similiarity to the exec system call.
793 It is an ongoing process to be certain the hardware in a machine
794 is properly shutdown, so do not be surprised if this code does not
795 initially work for you. It may help to enable device hotplugging
796 support. As of this writing the exact hardware interface is

1884 select GENERIC_ISA_DMA
1886 The Extended Industry Standard Architecture (EISA) bus was
1887 developed as an open alternative to the IBM MicroChannel bus.
1889 The EISA bus provided some of the features of the IBM MicroChannel
1890 bus while maintaining backward compatibility with cards made for
1891 the older ISA bus. The EISA bus saw limited use between 1988 and
1892 1995 when it was made obsolete by the PCI bus.
1894 Say Y here if you are building a kernel for an EISA-based machine.

1934 bool "Use 64-bit ELF format for building"
1937 A 64-bit kernel is usually built using the 64-bit ELF binary object
1938 format as it's one that allows arbitrary 64-bit constructs. For
1939 kernels that are loaded within the KSEG compatibility segments the
1940 32-bit ELF format can optionally be used resulting in a somewhat
1941 smaller binary, but this option is not explicitly supported by the
1942 toolchain and since binutils 2.14 it does not even work at all.
1944 Say Y to use the 64-bit format or N to use the 32-bit one.
1949 bool "Include IRIX binary compatibility"
1950 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1952 config MIPS32_COMPAT
1953 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1956 Select this option if you want Linux/MIPS 32-bit binary
1957 compatibility. Since all software available for Linux/MIPS is
1958 currently 32-bit you should say Y here.
1962 depends on MIPS32_COMPAT
1965 config SYSVIPC_COMPAT
1967 depends on COMPAT && SYSVIPC
1971 bool "Kernel support for o32 binaries"
1972 depends on MIPS32_COMPAT
1974 Select this option if you want to run o32 binaries. These are pure
1975 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1976 existing binaries are in this format.
1981 bool "Kernel support for n32 binaries"
1982 depends on MIPS32_COMPAT
1984 Select this option if you want to run n32 binaries. These are
1985 64-bit binaries using 32-bit quantities for addressing and certain
1986 data that would normally be 64-bit. They are used in special
1993 default y if MIPS32_O32 || MIPS32_N32
1996 bool "Enable seccomp to safely compute untrusted bytecode"
1997 depends on PROC_FS && BROKEN
2000 This kernel feature is useful for number crunching applications
2001 that may need to compute untrusted bytecode during their
2002 execution. By using pipes or other transports made available to
2003 the process as file descriptors supporting the read/write
2004 syscalls, it's possible to isolate those applications in
2005 their own address space using seccomp. Once seccomp is
2006 enabled via /proc/<pid>/seccomp, it cannot be disabled
2007 and the task is only allowed to execute a few safe syscalls
2008 defined by each seccomp mode.
2010 If unsure, say Y. Only embedded should say N here.
2013 bool "Power Management support (EXPERIMENTAL)"
2014 depends on EXPERIMENTAL && SOC_AU1X00
2017 tristate "Advanced Power Management Emulation"
2020 APM is a BIOS specification for saving power using several different
2021 techniques. This is mostly useful for battery powered systems with
2022 APM compliant BIOSes. If you say Y here, the system time will be
2023 reset after a RESUME operation, the /proc/apm device will provide
2024 battery status information, and user-space programs will receive
2025 notification of APM "events" (e.g. battery status change).
2027 In order to use APM, you will need supporting software. For location
2028 and more information, read <file:Documentation/pm.txt> and the
2029 Battery Powered Linux mini-HOWTO, available from
2030 <http://www.tldp.org/docs.html#howto>.
2032 This driver does not spin down disk drives (see the hdparm(8)
2033 manpage ("man 8 hdparm") for that), and it doesn't turn off
2034 VESA-compliant "green" monitors.
2036 Generally, if you don't have a battery in your machine, there isn't
2037 much point in using this driver and you should say N. If you get
2038 random kernel OOPSes or reboots that don't seem to be related to
2039 anything, try disabling/enabling this option (or disabling/enabling
