562 can simulate a MIPS32 4Kc system. This patch adds support for the
563 system architecture that currently is being simulated by Qemu. It
564 will eventually be removed again when Qemu has the capability to
565 simulate actual MIPS hardware platforms. More information on Qemu

1895 The Extended Industry Standard Architecture (EISA) bus was
1896 developed as an open alternative to the IBM MicroChannel bus.
1897
1898 The EISA bus provided some of the features of the IBM MicroChannel
1899 bus while maintaining backward compatibility with cards made for
1900 the older ISA bus. The EISA bus saw limited use between 1988 and
1901 1995 when it was made obsolete by the PCI bus.
1902
1903 Say Y here if you are building a kernel for an EISA-based machine.
1904
1905 Otherwise, say N.

1945 help
1946 A 64-bit kernel is usually built using the 64-bit ELF binary object
1947 format as it's one that allows arbitrary 64-bit constructs. For
1948 kernels that are loaded within the KSEG compatibility segments the
1949 32-bit ELF format can optionally be used resulting in a somewhat
1950 smaller binary, but this option is not explicitly supported by the
1951 toolchain and since binutils 2.14 it does not even work at all.
1952
1953 Say Y to use the 64-bit format or N to use the 32-bit one.

2004 This kernel feature is useful for number crunching applications
2005 that may need to compute untrusted bytecode during their
2006 execution. By using pipes or other transports made available to
2007 the process as file descriptors supporting the read/write
2008 syscalls, it's possible to isolate those applications in
2009 their own address space using seccomp. Once seccomp is
2010 enabled via /proc/<pid>/seccomp, it cannot be disabled
2011 and the task is only allowed to execute a few safe syscalls
2012 defined by each seccomp mode.

2023 ---help---
2024 APM is a BIOS specification for saving power using several different
2025 techniques. This is mostly useful for battery powered systems with
2026 APM compliant BIOSes. If you say Y here, the system time will be
2027 reset after a RESUME operation, the /proc/apm device will provide
2028 battery status information, and user-space programs will receive
2029 notification of APM "events" (e.g. battery status change).
2030
2031 In order to use APM, you will need supporting software. For location
2032 and more information, read <file:Documentation/pm.txt> and the
2033 Battery Powered Linux mini-HOWTO, available from
2034 <http://www.tldp.org/docs.html#howto>.
2035
2036 This driver does not spin down disk drives (see the hdparm(8)
2037 manpage ("man 8 hdparm") for that), and it doesn't turn off
2038 VESA-compliant "green" monitors.
2039
2040 Generally, if you don't have a battery in your machine, there isn't
2041 much point in using this driver and you should say N. If you get
2042 random kernel OOPSes or reboots that don't seem to be related to
2043 anything, try disabling/enabling this option (or disabling/enabling
2044 APM in your BIOS).
