1880 depends on HW_HAS_EISA
1883 The Extended Industry Standard Architecture (EISA) bus was
1884 developed as an open alternative to the IBM MicroChannel bus.
1886 The EISA bus provided some of the features of the IBM MicroChannel
1887 bus while maintaining backward compatibility with cards made for
1888 the older ISA bus. The EISA bus saw limited use between 1988 and
1889 1995 when it was made obsolete by the PCI bus.
1891 Say Y here if you are building a kernel for an EISA-based machine.

1898 bool "TURBOchannel support"
1899 depends on MACH_DECSTATION
1901 TurboChannel is a DEC (now Compaq (now HP)) bus for Alpha and MIPS
1902 processors. Documentation on writing device drivers for TurboChannel

1931 bool "Use 64-bit ELF format for building"
1934 A 64-bit kernel is usually built using the 64-bit ELF binary object
1935 format as it's one that allows arbitrary 64-bit constructs. For
1936 kernels that are loaded within the KSEG compatibility segments the
1937 32-bit ELF format can optionally be used resulting in a somewhat
1938 smaller binary, but this option is not explicitly supported by the
1939 toolchain and since binutils 2.14 it does not even work at all.
1941 Say Y to use the 64-bit format or N to use the 32-bit one.
1946 bool "Include IRIX binary compatibility"
1947 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1949 config MIPS32_COMPAT
1950 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1953 Select this option if you want Linux/MIPS 32-bit binary
1954 compatibility. Since all software available for Linux/MIPS is
1955 currently 32-bit you should say Y here.
1959 depends on MIPS32_COMPAT
1963 bool "Kernel support for o32 binaries"
1964 depends on MIPS32_COMPAT
1966 Select this option if you want to run o32 binaries. These are pure
1967 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1968 existing binaries are in this format.
1973 bool "Kernel support for n32 binaries"
1974 depends on MIPS32_COMPAT
1976 Select this option if you want to run n32 binaries. These are
1977 64-bit binaries using 32-bit quantities for addressing and certain
1978 data that would normally be 64-bit. They are used in special
1985 default y if MIPS32_O32 || MIPS32_N32
1988 bool "Enable seccomp to safely compute untrusted bytecode"
1989 depends on PROC_FS && BROKEN
1992 This kernel feature is useful for number crunching applications
1993 that may need to compute untrusted bytecode during their
1994 execution. By using pipes or other transports made available to
1995 the process as file descriptors supporting the read/write
1996 syscalls, it's possible to isolate those applications in
1997 their own address space using seccomp. Once seccomp is
1998 enabled via /proc/<pid>/seccomp, it cannot be disabled
1999 and the task is only allowed to execute a few safe syscalls
2000 defined by each seccomp mode.
2002 If unsure, say Y. Only embedded should say N here.
2005 bool "Power Management support (EXPERIMENTAL)"
2006 depends on EXPERIMENTAL && SOC_AU1X00
2009 tristate "Advanced Power Management Emulation"
2012 APM is a BIOS specification for saving power using several different
2013 techniques. This is mostly useful for battery powered systems with
2014 APM compliant BIOSes. If you say Y here, the system time will be
2015 reset after a RESUME operation, the /proc/apm device will provide
2016 battery status information, and user-space programs will receive
2017 notification of APM "events" (e.g. battery status change).
2019 In order to use APM, you will need supporting software. For location
2020 and more information, read <file:Documentation/pm.txt> and the
2021 Battery Powered Linux mini-HOWTO, available from
2022 <http://www.tldp.org/docs.html#howto>.
2024 This driver does not spin down disk drives (see the hdparm(8)
2025 manpage ("man 8 hdparm") for that), and it doesn't turn off
2026 VESA-compliant "green" monitors.
2028 Generally, if you don't have a battery in your machine, there isn't
2029 much point in using this driver and you should say N. If you get
2030 random kernel OOPSes or reboots that don't seem to be related to
2031 anything, try disabling/enabling this option (or disabling/enabling
