I've marked the Ubuntu 14.04 LTS (Trusty) task as Won't Fix. The
backport is not nearly as simple as the other releases and I don't feel
like the risk of regression is worth it on that release considering that
this is a new hardware enablement type of a feature and Ubuntu 14.04 LTS
only has 6 months of official support left. Users that are stuck on
Ubuntu 14.04 LTS will be able to use the enablement kernel to get this
feature:

Bug description:
  Description:

  Future Intel CPU's like Cascade Lake and GLK+ support Enhanced IBRS.
  Enhanced IBRS is a H/W mitigation technique for Spectre V2 bug. So,
  it's important for us to make sure that all the OSV's are using this
  feature.

  The patch that enables kernel support for this feature has been taken
  by Thomas and it's in TIP tree. So, please back port it to all the
  OSV's. Please find the patch here:
  https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?h=x86/pti&id=706d51681d636a0c4a5ef53395ec3b803e45ed4d

  Target Kernel:4.18
  Target Release: 18.10
