1890 developed as an open alternative to the IBM MicroChannel bus.
1892 The EISA bus provided some of the features of the IBM MicroChannel
1893 bus while maintaining backward compatibility with cards made for
1894 the older ISA bus. The EISA bus saw limited use between 1988 and
1895 1995 when it was made obsolete by the PCI bus.
1897 Say Y here if you are building a kernel for an EISA-based machine.

1937 bool "Use 64-bit ELF format for building"
1940 A 64-bit kernel is usually built using the 64-bit ELF binary object
1941 format as it's one that allows arbitrary 64-bit constructs. For
1942 kernels that are loaded within the KSEG compatibility segments the
1943 32-bit ELF format can optionally be used resulting in a somewhat
1944 smaller binary, but this option is not explicitly supported by the
1945 toolchain and since binutils 2.14 it does not even work at all.
1947 Say Y to use the 64-bit format or N to use the 32-bit one.
1952 bool "Include IRIX binary compatibility"
1953 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1955 config MIPS32_COMPAT
1956 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1959 Select this option if you want Linux/MIPS 32-bit binary
1960 compatibility. Since all software available for Linux/MIPS is
1961 currently 32-bit you should say Y here.
1965 depends on MIPS32_COMPAT
1969 bool "Kernel support for o32 binaries"
1970 depends on MIPS32_COMPAT
1972 Select this option if you want to run o32 binaries. These are pure
1973 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1974 existing binaries are in this format.
1979 bool "Kernel support for n32 binaries"
1980 depends on MIPS32_COMPAT
1982 Select this option if you want to run n32 binaries. These are
1983 64-bit binaries using 32-bit quantities for addressing and certain
1984 data that would normally be 64-bit. They are used in special
1991 default y if MIPS32_O32 || MIPS32_N32
1994 bool "Enable seccomp to safely compute untrusted bytecode"
1995 depends on PROC_FS && BROKEN
1998 This kernel feature is useful for number crunching applications
1999 that may need to compute untrusted bytecode during their
2000 execution. By using pipes or other transports made available to
2001 the process as file descriptors supporting the read/write
2002 syscalls, it's possible to isolate those applications in
2003 their own address space using seccomp. Once seccomp is
2004 enabled via /proc/<pid>/seccomp, it cannot be disabled
2005 and the task is only allowed to execute a few safe syscalls
2006 defined by each seccomp mode.
2008 If unsure, say Y. Only embedded should say N here.
2011 bool "Power Management support (EXPERIMENTAL)"
2012 depends on EXPERIMENTAL && SOC_AU1X00
2015 tristate "Advanced Power Management Emulation"
2018 APM is a BIOS specification for saving power using several different
2019 techniques. This is mostly useful for battery powered systems with
2020 APM compliant BIOSes. If you say Y here, the system time will be
2021 reset after a RESUME operation, the /proc/apm device will provide
2022 battery status information, and user-space programs will receive
2023 notification of APM "events" (e.g. battery status change).
2025 In order to use APM, you will need supporting software. For location
2026 and more information, read <file:Documentation/pm.txt> and the
2027 Battery Powered Linux mini-HOWTO, available from
2028 <http://www.tldp.org/docs.html#howto>.
2030 This driver does not spin down disk drives (see the hdparm(8)
2031 manpage ("man 8 hdparm") for that), and it doesn't turn off
2032 VESA-compliant "green" monitors.
2034 Generally, if you don't have a battery in your machine, there isn't
2035 much point in using this driver and you should say N. If you get
2036 random kernel OOPSes or reboots that don't seem to be related to
2037 anything, try disabling/enabling this option (or disabling/enabling
