Konstantin Belousov 7355a02bdd Mitigations for Microarchitectural Data Sampling. 
Microarchitectural buffers on some Intel processors utilizing
speculative execution may allow a local process to obtain a memory
disclosure.  An attacker may be able to read secret data from the
kernel or from a process when executing untrusted code (for example,
in a web browser).
