  Jim Mattson discovered that the KVM implementation in the Linux kernel
  mismanages the #BP and #OF exceptions. A local attacker in a guest virtual
  machine could use this to cause a denial of service (guest OS crash).

Simple backport needed for context ajustment. Already fixed for Xenial
and later series. Compile tested.
