	prompt "Initialize kernel stack variables at function entry"
	default INIT_STACK_NONE
	help
	  This option enables initialization of stack variables at
	  function entry time. This has the possibility to have the
	  greatest coverage (since all functions can have their
	  variables initialized), but the performance impact depends
	  on the function calling complexity of a given workload's
	  syscalls.

	  This chooses the level of coverage over classes of potentially
	  uninitialized variables. The selected class will be
	  initialized before use in a function.

	config INIT_STACK_NONE
		bool "no automatic initialization (weakest)"
		help
		  Disable automatic stack variable initialization.
		  This leaves the kernel vulnerable to the standard
		  classes of uninitialized stack variable exploits
		  and information exposures.

	config INIT_STACK_ALL
		bool "0xAA-init everything on the stack (strongest)"
		help
		  Initializes everything on the stack with a 0xAA
		  pattern. This is intended to eliminate all classes
		  of uninitialized stack variable exploits and information
		  exposures, even variables that were warned to have been
		  left uninitialized.
