config KEXEC
	bool "kexec system call (EXPERIMENTAL)"
	depends on SUPERH32 && EXPERIMENTAL && MMU
	help
	  kexec is a system call that implements the ability to shutdown your
	  current kernel, and to start another kernel.  It is like a reboot
	  but it is independent of the system firmware.  And like a reboot
	  you can start any kernel with it, not just Linux.

	  The name comes from the similarity to the exec system call.

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

config CRASH_DUMP
	bool "kernel crash dumps (EXPERIMENTAL)"
	depends on SUPERH32 && EXPERIMENTAL
	help
	  Generate crash dump after being started by kexec.
	  This should be normally only set in special crash dump kernels
	  which are loaded in the main kernel with kexec-tools into
	  a specially reserved region and then later executed after
	  a crash by kdump/kexec. The crash dump kernel must be compiled
	  to a memory address not used by the main kernel using
	  MEMORY_START.

	  For more details see Documentation/kdump/kdump.txt

config KEXEC_JUMP
	bool "kexec jump (EXPERIMENTAL)"

	  code via KEXEC

config SECCOMP
	bool "Enable seccomp to safely compute untrusted bytecode"
	depends on PROC_FS
	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 prctl, it cannot be disabled and the task is only
	  allowed to execute a few safe syscalls defined by each seccomp
	  mode.

	  If unsure, say N.

config SMP
	bool "Symmetric multi-processing support"
	depends on SYS_SUPPORTS_SMP
	select USE_GENERIC_SMP_HELPERS
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, like most personal computers, 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 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.

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

	  This allows you to specify the maximum number of CPUs which this

	  minimum value which makes sense is 2.

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

	  This enables support for gUSA (general UserSpace Atomicity).

	  CPUs, and is used by the libc, amongst others.

	  For additional information, design information can be found 
	  in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.

	  This should only be disabled for special cases where alternate
	  atomicity implementations exist.

config GUSA_RB
	bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
	depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
	help
	  Enabling this option will allow the kernel to implement some
	  atomic operations using a software implementation of load-locked/
	  store-conditional (LLSC). On machines which do not have hardware
	  LLSC, this should be more efficient than the other alternative of
	  disabling interrupts around the atomic sequence.

config SPARSE_IRQ
	bool "Support sparse irq numbering"
	depends on EXPERIMENTAL
	help
	  This enables support for sparse irqs. This is useful in general
	  as most CPUs have a fairly sparse array of IRQ vectors, which
	  the irq_desc then maps directly on to. Systems with a high
	  number of off-chip IRQs will want to treat this as
	  experimental until they have been independently verified.
