1991 is properly shutdown, so do not be surprised if this code does not
1992 initially work for you. It may help to enable device hotplugging
1993 support. As of this writing the exact hardware interface is
1994 strongly in flux, so no good recommendation can be made.

2000 help
2001 This kernel feature is useful for number crunching applications
2002 that may need to compute untrusted bytecode during their
2003 execution. By using pipes or other transports made available to
2004 the process as file descriptors supporting the read/write
2005 syscalls, it's possible to isolate those applications in
2006 their own address space using seccomp. Once seccomp is
2007 enabled via /proc/<pid>/seccomp, it cannot be disabled
2008 and the task is only allowed to execute a few safe syscalls
2009 defined by each seccomp mode.
2011 If unsure, say Y. Only embedded should say N here.

2072 The Extended Industry Standard Architecture (EISA) bus was
2073 developed as an open alternative to the IBM MicroChannel bus.
2075 The EISA bus provided some of the features of the IBM MicroChannel
2076 bus while maintaining backward compatibility with cards made for
2077 the older ISA bus. The EISA bus saw limited use between 1988 and
2078 1995 when it was made obsolete by the PCI bus.
