	  This kernel feature is useful for number crunching applications
	  that may need to compute untrusted bytecode during their
	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via /proc/<pid>/seccomp, it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  If unsure, say Y. Only embedded should say N here.

	help
	  When this is enabled, the kernel will support use of 64-bit floating
	  point registers with binaries using the O32 ABI along with the
	  EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
	  32-bit MIPS systems this support is at the cost of increasing the
	  size and complexity of the compiled FPU emulator. Thus if you are
	  running a MIPS32 system and know that none of your userland binaries
	  will require 64-bit floating point, you may wish to reduce the size
	  of your kernel & potentially improve FP emulation performance by
	  saying N here.

	  If unsure, say Y.

	  The Extended Industry Standard Architecture (EISA) bus was

	  The EISA bus provided some of the features of the IBM MicroChannel

	  1995 when it was made obsolete by the PCI bus.
