[Eric Desrochers]

A "BUG: scheduling while atomic" situation randomly occur when VMware guess is running Ubuntu kernel 3.13 series and hosted on VMware 6.0 and later,
with VMCI (Virtual Machine Communication Interface) turned on.

Upstream discussion confirms the need of the 3 upstream commits : https://patchwork.kernel.org/patch/9948741/
The VMware author of the patch suggested a backport from upstream of 3 patches he made.

The patches has been tested for more than 3 weeks now with a user affected by this situation, without any problem on both VMware < & > than VMware 6.0, and it run smootly for both with no new occurence ofthe bug. No regression found for Vmware < 6.0 and no occurence of a crash for VMware > 6.0
