Frederic CORNU a7b14306d5 Improve PTI detection even more 
when PTI detection relies on dmesg, dmesg output is checked first
then /var/log/dmesg if dmesg output lacks boot time messages

Frederic CORNU 608952ff71 Improve PTI detection 
In case of a busy or misconfigured server, kernel message buffer loop
can be filled with messages broadcasted later than boot time. So dmesg
command wont return boot time messages.

Grepping /var/log/dmesg fixes it and this log file location semms pretty
standard across many common distros

Vincent Brillault ad342cab06
Introduce "verbose" and "batch" modes 
Rewrite the way the output is processed:
- Define verbosity level (currently warn, info (default) & verbose)
- Add a batch mode, for simple machine parsing

RedHat uses a different configuration name 2018-01-08 12:59:12 +01:00
Vincent Brillault 66f7708095
Refactor RedHat support: 
- Isolate file check to different elif (allowing to add more)
- Do the PTI debugfs check first (faster and supposed to be dynamic)
- If pti_enable is 0, don't trust dmesg (supposed to be dynamic)
