Bug description:
  Posted Interrupts on Broadwell is really VT-d posted interrupts.
  Posted Interrupts for the processor are part of the APIC-V and was
  introduced in IVT. The idea is that the interrupt can be placed in a
  data structure for the guest and the guest can, under the right
  conditions, receive the interrupt without VM exiting. Chapter 29 of
  vol. c of the SDM has the currently public part of posted interrupts.

  Upstream Schedule:
  kernel: 4.4
  Xen: 4.7

  Target Ubuntu Release:
  Ubuntu 16.04
