Pull CPU speculation fixes from Borislav Petkov:
"Add the mitigation logic for Transient Scheduler Attacks (TSA)
TSA are new aspeculative side channel attacks related to the execution
timing of instructions under specific microarchitectural conditions.
In some cases, an attacker may be able to use this timing information
to infer data from other contexts, resulting in information leakage.
Add the usual controls of the mitigation and integrate it into the
existing speculation bugs infrastructure in the kernel"
