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

1894 The Extended Industry Standard Architecture (EISA) bus was
1895 developed as an open alternative to the IBM MicroChannel bus.
1897 The EISA bus provided some of the features of the IBM MicroChannel
1898 bus while maintaining backward compatibility with cards made for
1899 the older ISA bus. The EISA bus saw limited use between 1988 and
1900 1995 when it was made obsolete by the PCI bus.
1902 Say Y here if you are building a kernel for an EISA-based machine.

1942 bool "Use 64-bit ELF format for building"
1945 A 64-bit kernel is usually built using the 64-bit ELF binary object
1946 format as it's one that allows arbitrary 64-bit constructs. For
1947 kernels that are loaded within the KSEG compatibility segments the
1948 32-bit ELF format can optionally be used resulting in a somewhat
1949 smaller binary, but this option is not explicitly supported by the
1950 toolchain and since binutils 2.14 it does not even work at all.
1952 Say Y to use the 64-bit format or N to use the 32-bit one.

1961 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1964 Select this option if you want Linux/MIPS 32-bit binary
1965 compatibility. Since all software available for Linux/MIPS is
1966 currently 32-bit you should say Y here.

1979 bool "Kernel support for o32 binaries"
1980 depends on MIPS32_COMPAT
1982 Select this option if you want to run o32 binaries. These are pure
1983 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1984 existing binaries are in this format.
1989 bool "Kernel support for n32 binaries"
1990 depends on MIPS32_COMPAT
1992 Select this option if you want to run n32 binaries. These are
1993 64-bit binaries using 32-bit quantities for addressing and certain
1994 data that would normally be 64-bit. They are used in special
2001 default y if MIPS32_O32 || MIPS32_N32
2004 bool "Enable seccomp to safely compute untrusted bytecode"
2005 depends on PROC_FS && BROKEN
2008 This kernel feature is useful for number crunching applications
2009 that may need to compute untrusted bytecode during their
2010 execution. By using pipes or other transports made available to
2011 the process as file descriptors supporting the read/write
2012 syscalls, it's possible to isolate those applications in
2013 their own address space using seccomp. Once seccomp is
2014 enabled via /proc/<pid>/seccomp, it cannot be disabled
2015 and the task is only allowed to execute a few safe syscalls
2016 defined by each seccomp mode.
2018 If unsure, say Y. Only embedded should say N here.
2021 bool "Power Management support (EXPERIMENTAL)"
2022 depends on EXPERIMENTAL && SOC_AU1X00
2025 tristate "Advanced Power Management Emulation"
2028 APM is a BIOS specification for saving power using several different
2029 techniques. This is mostly useful for battery powered systems with
2030 APM compliant BIOSes. If you say Y here, the system time will be
2031 reset after a RESUME operation, the /proc/apm device will provide
2032 battery status information, and user-space programs will receive
2033 notification of APM "events" (e.g. battery status change).
2035 In order to use APM, you will need supporting software. For location
2036 and more information, read <file:Documentation/pm.txt> and the
2037 Battery Powered Linux mini-HOWTO, available from
2038 <http://www.tldp.org/docs.html#howto>.
2040 This driver does not spin down disk drives (see the hdparm(8)
2041 manpage ("man 8 hdparm") for that), and it doesn't turn off
2042 VESA-compliant "green" monitors.
2044 Generally, if you don't have a battery in your machine, there isn't
2045 much point in using this driver and you should say N. If you get
2046 random kernel OOPSes or reboots that don't seem to be related to
2047 anything, try disabling/enabling this option (or disabling/enabling
