776 you can start any kernel with it, not just Linux.

780 It is an ongoing process to be certain the hardware in a machine
781 is properly shutdown, so do not be surprised if this code does not
782 initially work for you. It may help to enable device hotplugging
783 support. As of this writing the exact hardware interface is

1911 bool "Use 64-bit ELF format for building"
1914 A 64-bit kernel is usually built using the 64-bit ELF binary object
1915 format as it's one that allows arbitrary 64-bit constructs. For
1916 kernels that are loaded within the KSEG compatibility segments the
1917 32-bit ELF format can optionally be used resulting in a somewhat
1918 smaller binary, but this option is not explicitly supported by the
1919 toolchain and since binutils 2.14 it does not even work at all.
1921 Say Y to use the 64-bit format or N to use the 32-bit one.
1926 bool "Include IRIX binary compatibility"
1927 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1929 config MIPS32_COMPAT
1930 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1933 Select this option if you want Linux/MIPS 32-bit binary
1934 compatibility. Since all software available for Linux/MIPS is
1935 currently 32-bit you should say Y here.
1939 depends on MIPS32_COMPAT
1943 bool "Kernel support for o32 binaries"
1944 depends on MIPS32_COMPAT
1946 Select this option if you want to run o32 binaries. These are pure
1947 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1948 existing binaries are in this format.
1953 bool "Kernel support for n32 binaries"
1954 depends on MIPS32_COMPAT
1956 Select this option if you want to run n32 binaries. These are
1957 64-bit binaries using 32-bit quantities for addressing and certain
1958 data that would normally be 64-bit. They are used in special
1965 default y if MIPS32_O32 || MIPS32_N32
1968 bool "Enable seccomp to safely compute untrusted bytecode"
1969 depends on PROC_FS && BROKEN
1972 This kernel feature is useful for number crunching applications
1973 that may need to compute untrusted bytecode during their
1974 execution. By using pipes or other transports made available to
1975 the process as file descriptors supporting the read/write
1976 syscalls, it's possible to isolate those applications in
1977 their own address space using seccomp. Once seccomp is
1978 enabled via /proc/<pid>/seccomp, it cannot be disabled
1979 and the task is only allowed to execute a few safe syscalls
1980 defined by each seccomp mode.
1982 If unsure, say Y. Only embedded should say N here.
1985 bool "Power Management support (EXPERIMENTAL)"
1986 depends on EXPERIMENTAL && SOC_AU1X00
1989 tristate "Advanced Power Management Emulation"
1992 APM is a BIOS specification for saving power using several different
1993 techniques. This is mostly useful for battery powered systems with
1994 APM compliant BIOSes. If you say Y here, the system time will be
1995 reset after a RESUME operation, the /proc/apm device will provide
1996 battery status information, and user-space programs will receive
1997 notification of APM "events" (e.g. battery status change).
1999 In order to use APM, you will need supporting software. For location
2000 and more information, read <file:Documentation/pm.txt> and the
2001 Battery Powered Linux mini-HOWTO, available from
2002 <http://www.tldp.org/docs.html#howto>.
2004 This driver does not spin down disk drives (see the hdparm(8)
2005 manpage ("man 8 hdparm") for that), and it doesn't turn off
2006 VESA-compliant "green" monitors.
2008 Generally, if you don't have a battery in your machine, there isn't
2009 much point in using this driver and you should say N. If you get
2010 random kernel OOPSes or reboots that don't seem to be related to
2011 anything, try disabling/enabling this option (or disabling/enabling
