From: Josh Poimboeuf <jpoimboe@xxxxxxxxxx> Enable CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL for both fedora and ARK. This prevents a lot of uninitialized stack variable exploits, with a minimal impact on performance. This feature is incompatible with CONFIG_KASAN, so it can't be enabled on debug kernels. Also, it's mutually exclusive with CONFIG_INIT_STACK_NONE=y.
