Twitter user stintel, in this thread:

mentions a possible problem with the new patches and the
nvidia driver:

"As if the @Intel bug isn't bad enough, #KPTI renders @nvidia driver
incompatible due to GPL-only symbol 'cpu_tlbstate'. #epicfail"

I've seen no obvious problems with kernel-3.10.0-693.11.6.el7.x86_64 and
nvidia-x11-drv-384.98-2.el7.elrepo.x86_64.

This includes running under KVM with vfio passthrough.
