This is upstream's implementation of Spectre v1 for Intel which is
different than what we currently have in Xenial. We need to review it
first to make sure we're not regressing, before we pull it in.

Bug description:
  SRU Justification

     The upstream process for stable tree updates is quite similar
     in scope to the Ubuntu SRU process, e.g., each patch has to
     demonstrably fix a bug, and each patch is vetted by upstream
     by originating either directly from a mainline/stable Linux tree
     or a minimally backported form of that patch. The 4.4.118 upstream
     stable stable patch set is now available. It should be included
     in the Ubuntu kernel as well.
