872 Some MIPS machines can be configured for either little or big endian
873 byte order. These modes require different kernels and a different
874 Linux distribution. In general there is one prefered byteorder for a
875 particular system but some systems are just as commonly used in the
876 one or the other endianess.

1837 help
1838 This kernel feature is useful for number crunching applications
1839 that may need to compute untrusted bytecode during their
1840 execution. By using pipes or other transports made available to
1841 the process as file descriptors supporting the read/write
1842 syscalls, it's possible to isolate those applications in
1843 their own address space using seccomp. Once seccomp is
1844 enabled via /proc/<pid>/seccomp, it cannot be disabled
1845 and the task is only allowed to execute a few safe syscalls
1846 defined by each seccomp mode.
1847
1848 If unsure, say Y. Only embedded should say N here.

1857 ---help---
1858 APM is a BIOS specification for saving power using several different
1859 techniques. This is mostly useful for battery powered systems with
1860 APM compliant BIOSes. If you say Y here, the system time will be
1861 reset after a RESUME operation, the /proc/apm device will provide
1862 battery status information, and user-space programs will receive
1863 notification of APM "events" (e.g. battery status change).
1864
1865 In order to use APM, you will need supporting software. For location
1866 and more information, read <file:Documentation/pm.txt> and the
1867 Battery Powered Linux mini-HOWTO, available from
1868 <http://www.tldp.org/docs.html#howto>.
1869
1870 This driver does not spin down disk drives (see the hdparm(8)
1871 manpage ("man 8 hdparm") for that), and it doesn't turn off
1872 VESA-compliant "green" monitors.
1873
1874 Generally, if you don't have a battery in your machine, there isn't
1875 much point in using this driver and you should say N. If you get
1876 random kernel OOPSes or reboots that don't seem to be related to
1877 anything, try disabling/enabling this option (or disabling/enabling
1878 APM in your BIOS).
