What does that mean 'bugs           : cpu_meltdown spectre_v1 spectre_v2
exactly?

curty@einstein:~$ grep . /sys/devices/system/cpu/vulnerabilities/*
/sys/devices/system/cpu/vulnerabilities/meltdown:Not affected
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Mitigation: __user
pointer sanitization
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full AMD
retpoline

The directly above seems more comforting in its verbose clarity somehow.
