	default y
	help
	  SPR_SR_DSX bit is status register bit indicating whether
	  the last exception has happened in delay slot.

	  OpenRISC architecture makes it optional to have it implemented
	  in hardware and the OR1200 does not have it.

	  Say N here if you know that your OpenRISC processor has
	  SPR_SR_DSX bit implemented. Say Y if you are unsure.

config CMDLINE

          On some architectures there is currently no way for the boot loader
          to pass arguments to the kernel. For these architectures, you should
          supply some command-line options at build time by entering them
          here.

	help
	  Make extra checks for space available on stack in some
          critical functions. This will cause kernel to run a bit slower,
	  but will catch most of kernel stack overruns and exit gracefully.

	  Say Y if you are unsure.

config JUMP_UPON_UNHANDLED_EXCEPTION
	bool "Try to die gracefully"
	default y
	help
	  Now this puts kernel into infinite loop after first oops. Till
	  your kernel crashes this doesn't have any influence.

	  Say Y if you are unsure.

config OPENRISC_ESR_EXCEPTION_BUG_CHECK
	bool "Check for possible ESR exception bug"
	default n
	help
	  This option enables some checks that might expose some problems
          in kernel.
