config KEXEC
	bool "kexec system call (EXPERIMENTAL)"
	depends on SUPERH32 && 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 && BROKEN_ON_SMP
	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
	  PHYSICAL_START.

	  For more details see Documentation/kdump/kdump.txt

config KEXEC_JUMP
	bool "kexec jump (EXPERIMENTAL)"
	depends on SUPERH32 && KEXEC && HIBERNATION
	help
	  Jump between original kernel and kexeced kernel and invoke
	  code via KEXEC

config PHYSICAL_START
	hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
	default MEMORY_START
	---help---
	  This gives the physical address where the kernel is loaded
	  and is ordinarily the same as MEMORY_START.

	  Different values are primarily used in the case of kexec on panic
	  where the fail safe kernel needs to run at a different address
	  than the panic-ed kernel.

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 CC_STACKPROTECTOR
	bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
	depends on SUPERH32
	help
	  This option turns on the -fstack-protector GCC feature. This
	  feature puts, at the beginning of functions, a canary value on
	  the stack just before the return address, and validates
	  the value just before actually returning.  Stack based buffer
	  overflows (that need to overwrite this return address) now also
	  overwrite the canary, which gets detected and the attack is then
	  neutralized via a kernel panic.

	  This feature requires gcc version 4.2 or above.

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>.
