These are the recommended patches for 4.12 for Hyper-V sockets
and LCOW. Based on: https://github.com/Microsoft/opengcs/pull/138
This also includes a cherry-pick from upstream which fixes the
ext4/nvdimm/pax failures we have seen since 4.11.2.

Note, on x86_64 for 4.12.9 a new kernel option,
HARDLOCKUP_CHECK_TIMESTAMP was added which defaults to enabled. It enables
a low pass filter to compensate for perf based hard lockup detection.
Added this option to the x86_64 4.12.x kernel confog file.
