1876 This kernel feature is useful for number crunching applications
1877 that may need to compute untrusted bytecode during their
1878 execution. By using pipes or other transports made available to
1879 the process as file descriptors supporting the read/write
1880 syscalls, it's possible to isolate those applications in
1881 their own address space using seccomp. Once seccomp is
1882 enabled via /proc/<pid>/seccomp, it cannot be disabled
1883 and the task is only allowed to execute a few safe syscalls
1884 defined by each seccomp mode.
1885
1886 If unsure, say Y. Only embedded should say N here.

1916 Find out whether you have a PCI motherboard. PCI is the name of a
1917 bus system, i.e. the way the CPU talks to the other stuff inside
1918 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
1919 say Y, otherwise N.

1945 The Extended Industry Standard Architecture (EISA) bus was
1946 developed as an open alternative to the IBM MicroChannel bus.
1947
1948 The EISA bus provided some of the features of the IBM MicroChannel
1949 bus while maintaining backward compatibility with cards made for
1950 the older ISA bus. The EISA bus saw limited use between 1988 and
1951 1995 when it was made obsolete by the PCI bus.
1952
1953 Say Y here if you are building a kernel for an EISA-based machine.
