Squash with ftrace:
Move stac_tracer_enabled into trace_sysctl_table while keeping the
CONFIG_STACK_TRACER ifdef. This is part of a greater effort to move ctl
tables into their respective subsystems which will reduce the merge
conflicts in kerenel/sysctl.c.

This should go into kernel/trace/trace_stack.c, and remove the #ifdef.

I'll also fix this little marker that I missed. And I'll not squash it,
as it is now going into trace_stack.c

I'll remove these comments from the commit message

Will send my V2 shortly with this modification.
