Linus Torvalds 138bcddb86 Add a mitigation for the speculative RAS (Return Address Stack) overflow 
vulnerability on AMD processors. In short, this is yet another issue
 where userspace poisons a microarchitectural structure which can then be
 used to leak privileged information through a side channel.
