1856 depends on HW_HAS_EISA
1859 The Extended Industry Standard Architecture (EISA) bus was
1860 developed as an open alternative to the IBM MicroChannel bus.
1862 The EISA bus provided some of the features of the IBM MicroChannel
1863 bus while maintaining backward compatibility with cards made for
1864 the older ISA bus. The EISA bus saw limited use between 1988 and
1865 1995 when it was made obsolete by the PCI bus.
1867 Say Y here if you are building a kernel for an EISA-based machine.

1877 TurboChannel is a DEC (now Compaq (now HP)) bus for Alpha and MIPS
1878 processors. Documentation on writing device drivers for TurboChannel

1907 bool "Use 64-bit ELF format for building"
1910 A 64-bit kernel is usually built using the 64-bit ELF binary object
1911 format as it's one that allows arbitrary 64-bit constructs. For
1912 kernels that are loaded within the KSEG compatibility segments the
1913 32-bit ELF format can optionally be used resulting in a somewhat
1914 smaller binary, but this option is not explicitly supported by the
1915 toolchain and since binutils 2.14 it does not even work at all.
1917 Say Y to use the 64-bit format or N to use the 32-bit one.
1922 bool "Include IRIX binary compatibility"
1923 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1925 config MIPS32_COMPAT
1926 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1929 Select this option if you want Linux/MIPS 32-bit binary
1930 compatibility. Since all software available for Linux/MIPS is
1931 currently 32-bit you should say Y here.
1935 depends on MIPS32_COMPAT
1939 bool "Kernel support for o32 binaries"
1940 depends on MIPS32_COMPAT
1942 Select this option if you want to run o32 binaries. These are pure
1943 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1944 existing binaries are in this format.
1949 bool "Kernel support for n32 binaries"
1950 depends on MIPS32_COMPAT
1952 Select this option if you want to run n32 binaries. These are
1953 64-bit binaries using 32-bit quantities for addressing and certain
1954 data that would normally be 64-bit. They are used in special
1961 default y if MIPS32_O32 || MIPS32_N32
1964 bool "Enable seccomp to safely compute untrusted bytecode"
1965 depends on PROC_FS && BROKEN
1968 This kernel feature is useful for number crunching applications
1969 that may need to compute untrusted bytecode during their
1970 execution. By using pipes or other transports made available to
1971 the process as file descriptors supporting the read/write
1972 syscalls, it's possible to isolate those applications in
1973 their own address space using seccomp. Once seccomp is
1974 enabled via /proc/<pid>/seccomp, it cannot be disabled
1975 and the task is only allowed to execute a few safe syscalls
1976 defined by each seccomp mode.
1978 If unsure, say Y. Only embedded should say N here.
1981 bool "Power Management support (EXPERIMENTAL)"
1982 depends on EXPERIMENTAL && SOC_AU1X00
1985 tristate "Advanced Power Management Emulation"
1988 APM is a BIOS specification for saving power using several different
1989 techniques. This is mostly useful for battery powered systems with
1990 APM compliant BIOSes. If you say Y here, the system time will be
1991 reset after a RESUME operation, the /proc/apm device will provide
1992 battery status information, and user-space programs will receive
1993 notification of APM "events" (e.g. battery status change).
1995 In order to use APM, you will need supporting software. For location
1996 and more information, read <file:Documentation/pm.txt> and the
1997 Battery Powered Linux mini-HOWTO, available from
1998 <http://www.tldp.org/docs.html#howto>.
2000 This driver does not spin down disk drives (see the hdparm(8)
2001 manpage ("man 8 hdparm") for that), and it doesn't turn off
2002 VESA-compliant "green" monitors.
2004 Generally, if you don't have a battery in your machine, there isn't
2005 much point in using this driver and you should say N. If you get
2006 random kernel OOPSes or reboots that don't seem to be related to
2007 anything, try disabling/enabling this option (or disabling/enabling
