 	  SPARC is a family of RISC microprocessors designed and marketed by
 	  Sun Microsystems, incorporated.  This port covers the newer 64-bit
 	  UltraSPARC.  The UltraLinux project maintains both the SPARC32 and
 	  SPARC64 ports; its web page is available at

 	default y
 	help
 	  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.

 	  This enables support for systems with more than one CPU. If you have

 	  one CPU, say Y.

 	  If you say N here, the kernel will run on single and multiprocessor
 	  machines, but will use only one CPU of a multiprocessor machine. If
 	  you say Y here, the kernel will run on many, but not all,
 	  singleprocessor machines. On a singleprocessor machine, the kernel
 	  will run faster if you say N here.

 	  People using multiprocessor machines who say Y here should also say
 	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
 	  Management" code will be disabled if you say Y here.

 	  See also the <file:Documentation/smp.txt>,
 	  <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at

 config PREEMPT
 	bool "Preemptible Kernel"
 	help
 	  This option reduces the latency of the kernel when reacting to
 	  real-time or interactive events by allowing a low priority process to
 	  be preempted even if it is in kernel mode executing a system call.
 	  This allows applications to run more reliably even when the system is
 	  under load.

 config ISA
 	bool
 	help
 	  Find out whether you have ISA slots on your motherboard.  ISA is the
 	  name of a bus system, i.e. the way the CPU talks to the other stuff
 	  inside your box.  Other bus systems are PCI, EISA, MicroChannel
 	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;

 	  If unsure, say Y.

 config EISA
 	bool
 	---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.

 config MCA
 	bool
 	help
 	  MicroChannel Architecture is found in some IBM PS/2 machines and
 	  laptops.  It is a bus system similar to PCI or ISA. See
 	  <file:Documentation/mca.txt> (and especially the web page given
 	  there) before attempting to build an MCA bus kernel.

 config PCMCIA
 	tristate
 	---help---
 	  Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
 	  computer.  These are credit-card size devices such as network cards,
 	  modems or hard drives often used with laptops computers.  There are
 	  actually two varieties of these cards: the older 16 bit PCMCIA cards
 	  and the newer 32 bit CardBus cards.  If you want to use CardBus
 	  cards, you need to say Y here and also to "CardBus support" below.

 	  To use your PC-cards, you will need supporting software from David
 	  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
 	  for location).  Please also read the PCMCIA-HOWTO, available from
 	  <http://www.tldp.org/docs.html#howto>.

 	  To compile this driver as modules, choose M here: the

 	  VESA. If you have PCI, say Y, otherwise N.

 	  The PCI-HOWTO, available from
