1846 their own address space using seccomp. Once seccomp is
1847 enabled via /proc/<pid>/seccomp, it cannot be disabled
1848 and the task is only allowed to execute a few safe syscalls
1849 defined by each seccomp mode.
1851 If unsure, say Y. Only embedded should say N here.

1861 APM is a BIOS specification for saving power using several different
1862 techniques. This is mostly useful for battery powered systems with
1863 APM compliant BIOSes. If you say Y here, the system time will be
1864 reset after a RESUME operation, the /proc/apm device will provide
1865 battery status information, and user-space programs will receive
1866 notification of APM "events" (e.g. battery status change).
1868 In order to use APM, you will need supporting software. For location
1869 and more information, read <file:Documentation/pm.txt> and the
1870 Battery Powered Linux mini-HOWTO, available from
1871 <http://www.tldp.org/docs.html#howto>.
1873 This driver does not spin down disk drives (see the hdparm(8)
1874 manpage ("man 8 hdparm") for that), and it doesn't turn off
1875 VESA-compliant "green" monitors.
1877 Generally, if you don't have a battery in your machine, there isn't
1878 much point in using this driver and you should say N. If you get
1879 random kernel OOPSes or reboots that don't seem to be related to
1880 anything, try disabling/enabling this option (or disabling/enabling
