2012 bool "Support for large 64-bit configurations"

2014 help
2015 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
2016 previous 64-bit processors which only supported 40 bit / 1TB. If you
2017 need processes of more than 1TB virtual address space, say Y here.

2021 config KEXEC
2022 bool "Kexec system call (EXPERIMENTAL)"
2023 depends on EXPERIMENTAL
2024 help
2025 kexec is a system call that implements the ability to shutdown your
2026 current kernel, and to start another kernel. It is like a reboot
2027 but it is independent of the system firmware. And like a reboot
2028 you can start any kernel with it, not just Linux.
2030 The name comes from the similarity to the exec system call.
2032 It is an ongoing process to be certain the hardware in a machine
2033 is properly shutdown, so do not be surprised if this code does not
2034 initially work for you. It may help to enable device hotplugging
2035 support. As of this writing the exact hardware interface is
2036 strongly in flux, so no good recommendation can be made.

2041 default y
2042 help
2043 This kernel feature is useful for number crunching applications
2044 that may need to compute untrusted bytecode during their
2045 execution. By using pipes or other transports made available to
2046 the process as file descriptors supporting the read/write
2047 syscalls, it's possible to isolate those applications in
2048 their own address space using seccomp. Once seccomp is
2049 enabled via /proc/<pid>/seccomp, it cannot be disabled
2050 and the task is only allowed to execute a few safe syscalls
2051 defined by each seccomp mode.
2053 If unsure, say Y. Only embedded should say N here.

2105 The Extended Industry Standard Architecture (EISA) bus was
2106 developed as an open alternative to the IBM MicroChannel bus.
2108 The EISA bus provided some of the features of the IBM MicroChannel
2109 bus while maintaining backward compatibility with cards made for
2110 the older ISA bus. The EISA bus saw limited use between 1988 and
2111 1995 when it was made obsolete by the PCI bus.
