	  People using multiprocessor machines who say Y here should also say
	  Y to "Enhanced Real Time Clock Support", below.

	  See also the <file:Documentation/smp.txt> and the SMP-HOWTO
	  available at <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

	depends on SMP
	default "64" if SGI_IP27
	default "2"
	help
	  This allows you to specify the maximum number of CPUs which this
	  kernel will support.  The maximum supported value is 32 for 32-bit
	  kernel and 64 for 64-bit kernels; the minimum value which makes
	  sense is 2.

	  This is purely to save memory - each supported CPU adds
	  approximately eight kilobytes to the kernel image.

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

	---help---
	  The Extended Industry Standard Architecture (EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older ISA bus.  The EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the PCI bus.

	  Say Y here if you are building a kernel for an EISA-based machine.

	  Otherwise, say N.

	help
	  A 64-bit kernel is usually built using the 64-bit ELF binary object
	  format as it's one that allows arbitrary 64-bit constructs.  For
	  kernels that are loaded within the KSEG compatibility segments the
	  32-bit ELF format can optionally be used resulting in a somewhat
	  smaller binary, but this option is not explicitly supported by the
	  toolchain and since binutils 2.14 it does not even work at all.

	  This kernel feature is useful for number crunching applications

	  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.
