[Bug 1494423] [NEW] Upstream commits for NUMA node performance in Hyper-V

 

Public bug reported:

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):
