[SRU][Vivid]Pull Request: Fixes for lp:1494423

[Joseph Salisbury]

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.

There are six patches required to accomplish this performance improvement.  
Those six patches also require two commits to function and compile
properly.

These patches are also requested in Trusty and the linux-lts-trusty kernels, but
they requred different backports, so SRU request for Trusty will be sent in 
a different SRU request.
