It reverts commit 3e39399ef4a742d994570488994be93ef17d4ef5. - The above commit added back a warning about CONFIG_STACK_TRACER NOT because the warning was necessary but to fix-up a problem where you could get an empty REMINDER block in the demg. However, CONFIG_STACK_TRACER really should not be in the reminder block. Even when configured-in it is not enabled, and thus has neglible impact. 2. It removes CONFIG_STACK_TRACER from DEBUG_COUNT which is the proper fix for the empty REMINDER block problem. This patch is for rt only.
