1865 bool "Support for large 64-bit configurations"
1866 depends on CPU_R10000 && 64BIT
1868 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1869 previous 64-bit processors which only supported 40 bit / 1TB. If you
1870 need processes of more than 1TB virtual address space, say Y here.
1871 This will result in additional memory usage, so it is not
1872 recommended for normal users.
1875 bool "Kexec system call (EXPERIMENTAL)"
1876 depends on EXPERIMENTAL
1878 kexec is a system call that implements the ability to shutdown your
1879 current kernel, and to start another kernel. It is like a reboot
1880 but it is indepedent of the system firmware. And like a reboot
1881 you can start any kernel with it, not just Linux.
1883 The name comes from the similiarity to the exec system call.
1885 It is an ongoing process to be certain the hardware in a machine
1886 is properly shutdown, so do not be surprised if this code does not
1887 initially work for you. It may help to enable device hotplugging
1888 support. As of this writing the exact hardware interface is
1889 strongly in flux, so no good recommendation can be made.
1892 bool "Enable seccomp to safely compute untrusted bytecode"
1893 depends on PROC_FS && BROKEN
1896 This kernel feature is useful for number crunching applications
1897 that may need to compute untrusted bytecode during their
1898 execution. By using pipes or other transports made available to
1899 the process as file descriptors supporting the read/write
1900 syscalls, it's possible to isolate those applications in
1901 their own address space using seccomp. Once seccomp is
1902 enabled via /proc/<pid>/seccomp, it cannot be disabled
1903 and the task is only allowed to execute a few safe syscalls
1904 defined by each seccomp mode.
1906 If unsure, say Y. Only embedded should say N here.

1965 The Extended Industry Standard Architecture (EISA) bus was
1966 developed as an open alternative to the IBM MicroChannel bus.
1968 The EISA bus provided some of the features of the IBM MicroChannel
1969 bus while maintaining backward compatibility with cards made for
1970 the older ISA bus. The EISA bus saw limited use between 1988 and
1971 1995 when it was made obsolete by the PCI bus.

2013 bool "Use 64-bit ELF format for building"
2016 A 64-bit kernel is usually built using the 64-bit ELF binary object
2017 format as it's one that allows arbitrary 64-bit constructs. For
2018 kernels that are loaded within the KSEG compatibility segments the
2019 32-bit ELF format can optionally be used resulting in a somewhat
2020 smaller binary, but this option is not explicitly supported by the
2021 toolchain and since binutils 2.14 it does not even work at all.
2023 Say Y to use the 64-bit format or N to use the 32-bit one.

2079 tristate "Advanced Power Management Emulation"
2082 APM is a BIOS specification for saving power using several different
2083 techniques. This is mostly useful for battery powered systems with
2084 APM compliant BIOSes. If you say Y here, the system time will be
2085 reset after a RESUME operation, the /proc/apm device will provide
2086 battery status information, and user-space programs will receive
2087 notification of APM "events" (e.g. battery status change).
2089 In order to use APM, you will need supporting software. For location
2090 and more information, read <file:Documentation/pm.txt> and the
2091 Battery Powered Linux mini-HOWTO, available from
2092 <http://www.tldp.org/docs.html#howto>.
2094 This driver does not spin down disk drives (see the hdparm(8)
2095 manpage ("man 8 hdparm") for that), and it doesn't turn off
2096 VESA-compliant "green" monitors.
2098 Generally, if you don't have a battery in your machine, there isn't
2099 much point in using this driver and you should say N. If you get
