1909 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1911 config MIPS32_COMPAT
1912 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1915 Select this option if you want Linux/MIPS 32-bit binary
1916 compatibility. Since all software available for Linux/MIPS is
1917 currently 32-bit you should say Y here.
1921 depends on MIPS32_COMPAT
1925 bool "Kernel support for o32 binaries"
1926 depends on MIPS32_COMPAT
1928 Select this option if you want to run o32 binaries. These are pure
1929 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1930 existing binaries are in this format.
1935 bool "Kernel support for n32 binaries"
1936 depends on MIPS32_COMPAT
1938 Select this option if you want to run n32 binaries. These are
1939 64-bit binaries using 32-bit quantities for addressing and certain
1940 data that would normally be 64-bit. They are used in special
1947 default y if MIPS32_O32 || MIPS32_N32
1950 bool "Enable seccomp to safely compute untrusted bytecode"
1951 depends on PROC_FS && BROKEN
1954 This kernel feature is useful for number crunching applications
1955 that may need to compute untrusted bytecode during their
1956 execution. By using pipes or other transports made available to
1957 the process as file descriptors supporting the read/write
1958 syscalls, it's possible to isolate those applications in
1959 their own address space using seccomp. Once seccomp is
1960 enabled via /proc/<pid>/seccomp, it cannot be disabled
1961 and the task is only allowed to execute a few safe syscalls
1962 defined by each seccomp mode.
1964 If unsure, say Y. Only embedded should say N here.
1967 bool "Power Management support (EXPERIMENTAL)"
1968 depends on EXPERIMENTAL && SOC_AU1X00
1971 tristate "Advanced Power Management Emulation"
1974 APM is a BIOS specification for saving power using several different
1975 techniques. This is mostly useful for battery powered systems with
1976 APM compliant BIOSes. If you say Y here, the system time will be
1977 reset after a RESUME operation, the /proc/apm device will provide
1978 battery status information, and user-space programs will receive
1979 notification of APM "events" (e.g. battery status change).
1981 In order to use APM, you will need supporting software. For location
1982 and more information, read <file:Documentation/pm.txt> and the
1983 Battery Powered Linux mini-HOWTO, available from
1984 <http://www.tldp.org/docs.html#howto>.
1986 This driver does not spin down disk drives (see the hdparm(8)
1987 manpage ("man 8 hdparm") for that), and it doesn't turn off
1988 VESA-compliant "green" monitors.
1990 Generally, if you don't have a battery in your machine, there isn't
1991 much point in using this driver and you should say N. If you get
1992 random kernel OOPSes or reboots that don't seem to be related to
1993 anything, try disabling/enabling this option (or disabling/enabling
