Subject: Yet another KPTI regression with 4.14.x series in a VM

Hi,

Fedora got a bug report on 4.14.11 of a panic when booting a
Fedora guest in a CentOS 6 VM, not reproducible with nopti.
The issue is still present as of 4.14.13 as well. The only
report is a panic screenshot
https://bugzilla.redhat.com/show_bug.cgi?id=1532458

I've lost track of all the fixes that have been flying around,
is this a new issue or has a fix not yet made it to stable?

Thanks,
Laura
