1910 smaller binary, but this option is not explicitly supported by the
1911 toolchain and since binutils 2.14 it does not even work at all.
1913 Say Y to use the 64-bit format or N to use the 32-bit one.
1918 bool "Include IRIX binary compatibility"
1919 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1921 config MIPS32_COMPAT
1922 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1925 Select this option if you want Linux/MIPS 32-bit binary
1926 compatibility. Since all software available for Linux/MIPS is
1927 currently 32-bit you should say Y here.
1931 depends on MIPS32_COMPAT
1935 bool "Kernel support for o32 binaries"
1936 depends on MIPS32_COMPAT
1938 Select this option if you want to run o32 binaries. These are pure
1939 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1940 existing binaries are in this format.
1945 bool "Kernel support for n32 binaries"
1946 depends on MIPS32_COMPAT
1948 Select this option if you want to run n32 binaries. These are
1949 64-bit binaries using 32-bit quantities for addressing and certain
1950 data that would normally be 64-bit. They are used in special
1957 default y if MIPS32_O32 || MIPS32_N32
1960 bool "Enable seccomp to safely compute untrusted bytecode"
1961 depends on PROC_FS && BROKEN
1964 This kernel feature is useful for number crunching applications
1965 that may need to compute untrusted bytecode during their
1966 execution. By using pipes or other transports made available to
1967 the process as file descriptors supporting the read/write
1968 syscalls, it's possible to isolate those applications in
1969 their own address space using seccomp. Once seccomp is
1970 enabled via /proc/<pid>/seccomp, it cannot be disabled
1971 and the task is only allowed to execute a few safe syscalls
1972 defined by each seccomp mode.
1974 If unsure, say Y. Only embedded should say N here.
1977 bool "Power Management support (EXPERIMENTAL)"
1978 depends on EXPERIMENTAL && SOC_AU1X00
1981 tristate "Advanced Power Management Emulation"
1984 APM is a BIOS specification for saving power using several different
1985 techniques. This is mostly useful for battery powered systems with
1986 APM compliant BIOSes. If you say Y here, the system time will be
1987 reset after a RESUME operation, the /proc/apm device will provide
1988 battery status information, and user-space programs will receive
1989 notification of APM "events" (e.g. battery status change).
1991 In order to use APM, you will need supporting software. For location
1992 and more information, read <file:Documentation/pm.txt> and the
1993 Battery Powered Linux mini-HOWTO, available from
1994 <http://www.tldp.org/docs.html#howto>.
1996 This driver does not spin down disk drives (see the hdparm(8)
1997 manpage ("man 8 hdparm") for that), and it doesn't turn off
1998 VESA-compliant "green" monitors.
2000 Generally, if you don't have a battery in your machine, there isn't
2001 much point in using this driver and you should say N. If you get
2002 random kernel OOPSes or reboots that don't seem to be related to
2003 anything, try disabling/enabling this option (or disabling/enabling
