A quick way to check what degree of protection there is on a system is 
to look at what is in /sys/devices/system/cpu/vulnerabilities:

ak@linux-f9zs:/sys/devices/system/cpu/vulnerabilities> ls
meltdown  spectre_v1  spectre_v2

ak@linux-f9zs:/sys/devices/system/cpu/vulnerabilities> cat spectre_v1 
spectre_v2 meltdown
Vulnerable
Mitigation: Full generic retpoline
Mitigation: PTI

Of course, outdated, unprotected kernels do not have this directory at all.


Paul, perhaps this could go to release notes?
