Public bug reported:

== SRU Justification ==

Impact: systems with CPUs lacking virtual NMI support are no longer able
to load the kvm_intel module, and thus not able to use KVM functionality

Fix: cherry-pick re-introducing support for software NMI support

Regression Potential: applied upstream in 4.15 and 4.14.3, tested and
verified by multiple people

--

the original dropping of support was (functionally) reverted after
upstream got notified of how many CPUs were actually affected

see 
https://lkml.kernel.org/r/<1509971473-74491-1-git-send-email-pbonz...@redhat.com>
 for upstream patch re-introducing support
see 
https://lkml.kernel.org/r/<1490618297-10581-2-git-send-email-pbonz...@redhat.com>
 for the original upstream patch dropping support and following discusison

I'll send an SRU patch.
