	  This lets you select the page size of the kernel.

	  8KB and 64KB work quite well, since SPARC ELF sections
	  provide for up to 64KB alignment.

config SECCOMP
	bool "Enable seccomp to safely compute untrusted bytecode"
	depends on PROC_FS
	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.

config SMP
	bool "Symmetric multi-processing support"
	help
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more than
	  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 single-processor machines.
	  On a single-processor machine, the kernel will run faster if you say
	  N here.

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

	default y
	help
	  This adds a driver for the UltraSPARC-III memory controller.
	  Loading this driver allows exact mnemonic strings to be
	  printed in the event of a memory error, so that the faulty DIMM
	  on the motherboard can be matched to the error.

	  If in doubt, say Y, as this information can be very useful.

config PCMCIA

	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
	  modules will be called pcmcia_core and ds.

config PCI

	select ARCH_SUPPORTS_MSI
	help
	  Find out whether your system includes a PCI bus. PCI is the name of
	  a bus system, i.e. the way the CPU talks to the other stuff inside
	  your box.  If you say Y here, the kernel will include drivers and
	  infrastructure code to support PCI bus devices.

	  If you say Y, the OpenPROM device tree will be available as a
	  virtual file system, which you can mount to /proc/openprom by "mount
	  -t openpromfs none /proc/openprom".

	  To compile the /proc/openprom support as a module, choose M here: the
	  module will be called openpromfs.  If unsure, choose M.

	  SMT scheduler support improves the CPU scheduler's decision making

	  in some places. If unsure say N here.

config SCHED_MC

	  Multi-core scheduler support improves the CPU scheduler's decision

	help
	  Say Y here if you want to be able to pass default arguments to
	  the kernel. This will be overridden by the bootloader, if you
	  use one (such as SILO). This is most useful if you want to boot
	  a kernel from TFTP, and want default options to be available
	  with having them passed on the command line.

	  NOTE: This option WILL override the PROM bootargs setting!
