Noticed C6 had a kernel update on Friday.
2.6.32-696.18.7.el6.x86_64
What is the flag in /proc/cpuinfo that indicates the KPTI patch for
Meltdown CVE-2017-5754 for C6?

Some distros are using "kaiser" some like Fedora are using "pti". Also
noticed some (like Fedora) are displaying "cpu_insecure" under the
bugs: heading of cpuinfo.
