1851 depends on HW_HAS_EISA
1854 The Extended Industry Standard Architecture (EISA) bus was
1855 developed as an open alternative to the IBM MicroChannel bus.
1857 The EISA bus provided some of the features of the IBM MicroChannel
1858 bus while maintaining backward compatibility with cards made for
1859 the older ISA bus. The EISA bus saw limited use between 1988 and
1860 1995 when it was made obsolete by the PCI bus.
1862 Say Y here if you are building a kernel for an EISA-based machine.

1869 bool "TURBOchannel support"
1870 depends on MACH_DECSTATION
1872 TurboChannel is a DEC (now Compaq (now HP)) bus for Alpha and MIPS
1873 processors. Documentation on writing device drivers for TurboChannel

1902 bool "Use 64-bit ELF format for building"
1905 A 64-bit kernel is usually built using the 64-bit ELF binary object
1906 format as it's one that allows arbitrary 64-bit constructs. For
1907 kernels that are loaded within the KSEG compatibility segments the
1908 32-bit ELF format can optionally be used resulting in a somewhat
1909 smaller binary, but this option is not explicitly supported by the
1910 toolchain and since binutils 2.14 it does not even work at all.
1912 Say Y to use the 64-bit format or N to use the 32-bit one.
1917 bool "Include IRIX binary compatibility"
1918 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1920 config MIPS32_COMPAT
1921 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1924 Select this option if you want Linux/MIPS 32-bit binary
1925 compatibility. Since all software available for Linux/MIPS is
1926 currently 32-bit you should say Y here.
1930 depends on MIPS32_COMPAT
1934 bool "Kernel support for o32 binaries"
1935 depends on MIPS32_COMPAT
1937 Select this option if you want to run o32 binaries. These are pure
1938 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1939 existing binaries are in this format.
1944 bool "Kernel support for n32 binaries"
1945 depends on MIPS32_COMPAT
1947 Select this option if you want to run n32 binaries. These are
1948 64-bit binaries using 32-bit quantities for addressing and certain
1949 data that would normally be 64-bit. They are used in special
1956 default y if MIPS32_O32 || MIPS32_N32
1959 bool "Enable seccomp to safely compute untrusted bytecode"
1960 depends on PROC_FS && BROKEN
1963 This kernel feature is useful for number crunching applications
1964 that may need to compute untrusted bytecode during their
1965 execution. By using pipes or other transports made available to
1966 the process as file descriptors supporting the read/write
1967 syscalls, it's possible to isolate those applications in
1968 their own address space using seccomp. Once seccomp is
1969 enabled via /proc/<pid>/seccomp, it cannot be disabled
1970 and the task is only allowed to execute a few safe syscalls
1971 defined by each seccomp mode.
1973 If unsure, say Y. Only embedded should say N here.
1976 bool "Power Management support (EXPERIMENTAL)"
1977 depends on EXPERIMENTAL && SOC_AU1X00
1980 tristate "Advanced Power Management Emulation"
1983 APM is a BIOS specification for saving power using several different
1984 techniques. This is mostly useful for battery powered systems with
1985 APM compliant BIOSes. If you say Y here, the system time will be
1986 reset after a RESUME operation, the /proc/apm device will provide
1987 battery status information, and user-space programs will receive
1988 notification of APM "events" (e.g. battery status change).
1990 In order to use APM, you will need supporting software. For location
1991 and more information, read <file:Documentation/pm.txt> and the
1992 Battery Powered Linux mini-HOWTO, available from
1993 <http://www.tldp.org/docs.html#howto>.
1995 This driver does not spin down disk drives (see the hdparm(8)
1996 manpage ("man 8 hdparm") for that), and it doesn't turn off
1997 VESA-compliant "green" monitors.
1999 Generally, if you don't have a battery in your machine, there isn't
2000 much point in using this driver and you should say N. If you get
2001 random kernel OOPSes or reboots that don't seem to be related to
2002 anything, try disabling/enabling this option (or disabling/enabling
