i    The  Spectre  variant  2  vulnerability  allows the speculative\r
i    execution   of  incorrect  (in  an  attacker-controllable  way)\r
i    indirect  branch  predictions,  resulting  in  the  ability  to\r
i    exfiltrate  information  via side channels. The kernel has been\r
i    reasonably  well  protected  against this variant since shortly\r
i    after  its  disclosure in January. It is, however, possible for\r
i    user-space  processes  to  use Spectre v2 to attack each other;\r
i    thus  far,  the  mainline  kernel has offered relatively little\r
i    protection  against  such  attacks. A recent proposal from Jiri\r
i    Kosina  may  change  that  situation,  but there are still some\r
i    disagreements around the details.\r
