  1553. A 64-bit kernel is usually built using the 64-bit ELF binary object
  1554. format as it's one that allows arbitrary 64-bit constructs. For
  1555. kernels that are loaded within the KSEG compatibility segments the
  1556. 32-bit ELF format can optionally be used resulting in a somewhat
  1557. smaller binary, but this option is not explicitly supported by the
  1558. toolchain and since binutils 2.14 it does not even work at all.
  1559. Say Y to use the 64-bit format or N to use the 32-bit one.
  1560. If unsure say Y.

  1600. This kernel feature is useful for number crunching applications
  1601. that may need to compute untrusted bytecode during their
  1602. execution. By using pipes or other transports made available to
  1603. the process as file descriptors supporting the read/write
  1604. syscalls, it's possible to isolate those applications in
  1605. their own address space using seccomp. Once seccomp is
  1606. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1607. and the task is only allowed to execute a few safe syscalls
  1608. defined by each seccomp mode.

  1617. APM is a BIOS specification for saving power using several different
  1618. techniques. This is mostly useful for battery powered systems with
  1619. APM compliant BIOSes. If you say Y here, the system time will be
  1620. reset after a RESUME operation, the /proc/apm device will provide
  1621. battery status information, and user-space programs will receive
  1622. notification of APM "events" (e.g. battery status change).
  1623. In order to use APM, you will need supporting software. For location
  1624. and more information, read <file:Documentation/pm.txt> and the
  1625. Battery Powered Linux mini-HOWTO, available from
  1626. <http://www.tldp.org/docs.html#howto>.
  1627. This driver does not spin down disk drives (see the hdparm(8)
  1628. manpage ("man 8 hdparm") for that), and it doesn't turn off
  1629. VESA-compliant "green" monitors.
  1630. Generally, if you don't have a battery in your machine, there isn't
  1631. much point in using this driver and you should say N. If you get
  1632. random kernel OOPSes or reboots that don't seem to be related to
  1633. anything, try disabling/enabling this option (or disabling/enabling
  1634. APM in your BIOS).
