1860 This kernel feature is useful for number crunching applications
1861 that may need to compute untrusted bytecode during their
1862 execution. By using pipes or other transports made available to
1863 the process as file descriptors supporting the read/write
1864 syscalls, it's possible to isolate those applications in
1865 their own address space using seccomp. Once seccomp is
1866 enabled via /proc/<pid>/seccomp, it cannot be disabled
1867 and the task is only allowed to execute a few safe syscalls
1868 defined by each seccomp mode.
1870 If unsure, say Y. Only embedded should say N here.

1880 APM is a BIOS specification for saving power using several different
1881 techniques. This is mostly useful for battery powered systems with
1882 APM compliant BIOSes. If you say Y here, the system time will be
1883 reset after a RESUME operation, the /proc/apm device will provide
1884 battery status information, and user-space programs will receive
1885 notification of APM "events" (e.g. battery status change).
1887 In order to use APM, you will need supporting software. For location
1888 and more information, read <file:Documentation/pm.txt> and the
1889 Battery Powered Linux mini-HOWTO, available from
1890 <http://www.tldp.org/docs.html#howto>.
1892 This driver does not spin down disk drives (see the hdparm(8)
1893 manpage ("man 8 hdparm") for that), and it doesn't turn off
1894 VESA-compliant "green" monitors.
1896 Generally, if you don't have a battery in your machine, there isn't
1897 much point in using this driver and you should say N. If you get
1898 random kernel OOPSes or reboots that don't seem to be related to
1899 anything, try disabling/enabling this option (or disabling/enabling
