[$] Trying to get STACKLEAK into the kernel

The STACKLEAK kernel security feature has been in the works for quite sometime now, but has not, as yet, made its way into the mainline. That is notfor lack of trying, as Alexander Popov has posted 15 separate versions ofthe patch set since May 2017. He described STACKLEAK and its tortuous pathtoward the mainline in a talk[YouTube video] at the 2018Linux Security Summit.
