2041 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
2042 previous 64-bit processors which only supported 40 bit / 1TB. If you
2043 need processes of more than 1TB virtual address space, say Y here.

2050 help
2051 kexec is a system call that implements the ability to shutdown your
2052 current kernel, and to start another kernel. It is like a reboot
2053 but it is independent of the system firmware. And like a reboot
2054 you can start any kernel with it, not just Linux.
2056 The name comes from the similarity to the exec system call.
2058 It is an ongoing process to be certain the hardware in a machine
2059 is properly shutdown, so do not be surprised if this code does not
2060 initially work for you. It may help to enable device hotplugging
2061 support. As of this writing the exact hardware interface is
2062 strongly in flux, so no good recommendation can be made.

2068 help
2069 This kernel feature is useful for number crunching applications
2070 that may need to compute untrusted bytecode during their
2071 execution. By using pipes or other transports made available to
2072 the process as file descriptors supporting the read/write
2073 syscalls, it's possible to isolate those applications in
2074 their own address space using seccomp. Once seccomp is
2075 enabled via /proc/<pid>/seccomp, it cannot be disabled
2076 and the task is only allowed to execute a few safe syscalls
2077 defined by each seccomp mode.
2079 If unsure, say Y. Only embedded should say N here.

2131 The Extended Industry Standard Architecture (EISA) bus was
2132 developed as an open alternative to the IBM MicroChannel bus.
2134 The EISA bus provided some of the features of the IBM MicroChannel
2135 bus while maintaining backward compatibility with cards made for
2136 the older ISA bus. The EISA bus saw limited use between 1988 and
2137 1995 when it was made obsolete by the PCI bus.
