1896 The Extended Industry Standard Architecture (EISA) bus was
1897 developed as an open alternative to the IBM MicroChannel bus.
1899 The EISA bus provided some of the features of the IBM MicroChannel
1900 bus while maintaining backward compatibility with cards made for
1901 the older ISA bus. The EISA bus saw limited use between 1988 and
1902 1995 when it was made obsolete by the PCI bus.
1904 Say Y here if you are building a kernel for an EISA-based machine.

1944 bool "Use 64-bit ELF format for building"
1947 A 64-bit kernel is usually built using the 64-bit ELF binary object
1948 format as it's one that allows arbitrary 64-bit constructs. For
1949 kernels that are loaded within the KSEG compatibility segments the
1950 32-bit ELF format can optionally be used resulting in a somewhat
1951 smaller binary, but this option is not explicitly supported by the
1952 toolchain and since binutils 2.14 it does not even work at all.
1954 Say Y to use the 64-bit format or N to use the 32-bit one.

1963 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1966 Select this option if you want Linux/MIPS 32-bit binary
1967 compatibility. Since all software available for Linux/MIPS is
1968 currently 32-bit you should say Y here.
1972 depends on MIPS32_COMPAT
1976 bool "Kernel support for o32 binaries"
1977 depends on MIPS32_COMPAT
1979 Select this option if you want to run o32 binaries. These are pure
1980 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1981 existing binaries are in this format.
1986 bool "Kernel support for n32 binaries"
1987 depends on MIPS32_COMPAT
1989 Select this option if you want to run n32 binaries. These are
1990 64-bit binaries using 32-bit quantities for addressing and certain
1991 data that would normally be 64-bit. They are used in special
1998 default y if MIPS32_O32 || MIPS32_N32
2001 bool "Enable seccomp to safely compute untrusted bytecode"
2002 depends on PROC_FS && BROKEN
2005 This kernel feature is useful for number crunching applications
2006 that may need to compute untrusted bytecode during their
2007 execution. By using pipes or other transports made available to
2008 the process as file descriptors supporting the read/write
2009 syscalls, it's possible to isolate those applications in
2010 their own address space using seccomp. Once seccomp is
2011 enabled via /proc/<pid>/seccomp, it cannot be disabled
2012 and the task is only allowed to execute a few safe syscalls
2013 defined by each seccomp mode.
2015 If unsure, say Y. Only embedded should say N here.

2022 tristate "Advanced Power Management Emulation"
2025 APM is a BIOS specification for saving power using several different
2026 techniques. This is mostly useful for battery powered systems with
2027 APM compliant BIOSes. If you say Y here, the system time will be
2028 reset after a RESUME operation, the /proc/apm device will provide
2029 battery status information, and user-space programs will receive
2030 notification of APM "events" (e.g. battery status change).
2032 In order to use APM, you will need supporting software. For location
2033 and more information, read <file:Documentation/pm.txt> and the
2034 Battery Powered Linux mini-HOWTO, available from
2035 <http://www.tldp.org/docs.html#howto>.
2037 This driver does not spin down disk drives (see the hdparm(8)
2038 manpage ("man 8 hdparm") for that), and it doesn't turn off
2039 VESA-compliant "green" monitors.
2041 Generally, if you don't have a battery in your machine, there isn't
2042 much point in using this driver and you should say N. If you get
2043 random kernel OOPSes or reboots that don't seem to be related to
2044 anything, try disabling/enabling this option (or disabling/enabling
