532 Qemu is a software emulator which among other architectures also
533 can simulate a MIPS32 4Kc system. This patch adds support for the
534 system architecture that currently is being simulated by Qemu. It
535 will eventually be removed again when Qemu has the capability to
536 simulate actual MIPS hardware platforms. More information on Qemu
537 can be found at http://www.linux-mips.org/wiki/Qemu.

922 Some MIPS machines can be configured for either little or big endian
5e83d430 923 byte order. These modes require different kernels and a different

1873 help
1874 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
1875 previous 64-bit processors which only supported 40 bit / 1TB. If you
1876 need processes of more than 1TB virtual address space, say Y here.
1877 This will result in additional memory usage, so it is not
1878 recommended for normal users.

1880config KEXEC
1881 bool "Kexec system call (EXPERIMENTAL)"
1882 depends on EXPERIMENTAL
1883 help
1884 kexec is a system call that implements the ability to shutdown your
1885 current kernel, and to start another kernel. It is like a reboot
1886 but it is indepedent of the system firmware. And like a reboot
1887 you can start any kernel with it, not just Linux.
1888
1889 The name comes from the similiarity to the exec system call.
1890
1891 It is an ongoing process to be certain the hardware in a machine
1892 is properly shutdown, so do not be surprised if this code does not
1893 initially work for you. It may help to enable device hotplugging
1894 support. As of this writing the exact hardware interface is
1895 strongly in flux, so no good recommendation can be made.

1901 help
1902 This kernel feature is useful for number crunching applications
1903 that may need to compute untrusted bytecode during their
1904 execution. By using pipes or other transports made available to
1905 the process as file descriptors supporting the read/write
1906 syscalls, it's possible to isolate those applications in
1907 their own address space using seccomp. Once seccomp is
1908 enabled via /proc/<pid>/seccomp, it cannot be disabled
1909 and the task is only allowed to execute a few safe syscalls
1910 defined by each seccomp mode.
1911
1912 If unsure, say Y. Only embedded should say N here.

1971 The Extended Industry Standard Architecture (EISA) bus was
1972 developed as an open alternative to the IBM MicroChannel bus.
1973
1974 The EISA bus provided some of the features of the IBM MicroChannel
1975 bus while maintaining backward compatibility with cards made for
1976 the older ISA bus. The EISA bus saw limited use between 1988 and
1977 1995 when it was made obsolete by the PCI bus.
