1912 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN
1914 config MIPS32_COMPAT
1915 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1918 Select this option if you want Linux/MIPS 32-bit binary
1919 compatibility. Since all software available for Linux/MIPS is
1920 currently 32-bit you should say Y here.
1924 depends on MIPS32_COMPAT
1928 bool "Kernel support for o32 binaries"
1929 depends on MIPS32_COMPAT
1931 Select this option if you want to run o32 binaries. These are pure
1932 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1933 existing binaries are in this format.
1938 bool "Kernel support for n32 binaries"
1939 depends on MIPS32_COMPAT
1941 Select this option if you want to run n32 binaries. These are
1942 64-bit binaries using 32-bit quantities for addressing and certain
1943 data that would normally be 64-bit. They are used in special
1950 default y if MIPS32_O32 || MIPS32_N32
1953 bool "Enable seccomp to safely compute untrusted bytecode"
1954 depends on PROC_FS && BROKEN
1957 This kernel feature is useful for number crunching applications
1958 that may need to compute untrusted bytecode during their
1959 execution. By using pipes or other transports made available to
1960 the process as file descriptors supporting the read/write
1961 syscalls, it's possible to isolate those applications in
1962 their own address space using seccomp. Once seccomp is
1963 enabled via /proc/<pid>/seccomp, it cannot be disabled
1964 and the task is only allowed to execute a few safe syscalls
1965 defined by each seccomp mode.
1967 If unsure, say Y. Only embedded should say N here.
1970 bool "Power Management support (EXPERIMENTAL)"
1971 depends on EXPERIMENTAL && SOC_AU1X00
1974 tristate "Advanced Power Management Emulation"
1977 APM is a BIOS specification for saving power using several different
1978 techniques. This is mostly useful for battery powered systems with
1979 APM compliant BIOSes. If you say Y here, the system time will be
1980 reset after a RESUME operation, the /proc/apm device will provide
1981 battery status information, and user-space programs will receive
1982 notification of APM "events" (e.g. battery status change).
1984 In order to use APM, you will need supporting software. For location
1985 and more information, read <file:Documentation/pm.txt> and the
1986 Battery Powered Linux mini-HOWTO, available from
1987 <http://www.tldp.org/docs.html#howto>.
1989 This driver does not spin down disk drives (see the hdparm(8)
1990 manpage ("man 8 hdparm") for that), and it doesn't turn off
1991 VESA-compliant "green" monitors.
1993 Generally, if you don't have a battery in your machine, there isn't
1994 much point in using this driver and you should say N. If you get
1995 random kernel OOPSes or reboots that don't seem to be related to
1996 anything, try disabling/enabling this option (or disabling/enabling
