The primary 6 commits are currently requiring 22 prerequisite commits
and still require addition patches.  Some of those commits change core
networking and the sk_buff struct.

The following prereq commit required extensive backporting:

    net: reorganize sk_buff for faster __copy_skb_header()

Due to this need to change core networking, approval for a stable
release update would not be acked.

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):
