["Joshua R. Poulson" <jopoulso@xxxxxxxxxxxxx>]

Joe, is this over and above Bug 1519917? That one may supercede this
one. We are performing full functional tests on 1519917 and it's eating
a lot of cycles, so to speak.

Bug description:
  Microsoft has investigated networking with NUMA nodes and Hyper-V and
  found a number of areas where Linux performance could be corrected to
  be in line with other virtual machine types.

  Please include the following commits and their necessary prerequisites
  (which have been accepted upstream into the 4.2 kernel series) into
  the kernels for 15.10, 15.04, 14.04 (including HWE), and 12.04
  (including HWE):
