915 Some MIPS machines can be configured for either little or big endian
916 byte order. These modes require different kernels and a different

1857 bool "Kernel support for o32 binaries"
1858 depends on MIPS32_COMPAT
1860 Select this option if you want to run o32 binaries. These are pure
1861 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1862 existing binaries are in this format.
1867 bool "Kernel support for n32 binaries"
1868 depends on MIPS32_COMPAT
1870 Select this option if you want to run n32 binaries. These are
1871 64-bit binaries using 32-bit quantities for addressing and certain
1872 data that would normally be 64-bit. They are used in special
1879 default y if MIPS32_O32 || MIPS32_N32
1882 bool "Enable seccomp to safely compute untrusted bytecode"
1883 depends on PROC_FS && BROKEN
1886 This kernel feature is useful for number crunching applications
1887 that may need to compute untrusted bytecode during their
1888 execution. By using pipes or other transports made available to
1889 the process as file descriptors supporting the read/write
1890 syscalls, it's possible to isolate those applications in
1891 their own address space using seccomp. Once seccomp is
1892 enabled via /proc/<pid>/seccomp, it cannot be disabled
1893 and the task is only allowed to execute a few safe syscalls
1894 defined by each seccomp mode.
1896 If unsure, say Y. Only embedded should say N here.
1899 bool "Power Management support (EXPERIMENTAL)"
1900 depends on EXPERIMENTAL && SOC_AU1X00
1903 tristate "Advanced Power Management Emulation"
1906 APM is a BIOS specification for saving power using several different
1907 techniques. This is mostly useful for battery powered systems with
1908 APM compliant BIOSes. If you say Y here, the system time will be
1909 reset after a RESUME operation, the /proc/apm device will provide
1910 battery status information, and user-space programs will receive
1911 notification of APM "events" (e.g. battery status change).
1913 In order to use APM, you will need supporting software. For location
1914 and more information, read <file:Documentation/pm.txt> and the
1915 Battery Powered Linux mini-HOWTO, available from
1916 <http://www.tldp.org/docs.html#howto>.
1918 This driver does not spin down disk drives (see the hdparm(8)
1919 manpage ("man 8 hdparm") for that), and it doesn't turn off
1920 VESA-compliant "green" monitors.
1922 Generally, if you don't have a battery in your machine, there isn't
1923 much point in using this driver and you should say N. If you get
1924 random kernel OOPSes or reboots that don't seem to be related to
1925 anything, try disabling/enabling this option (or disabling/enabling
