I'm confused: is it 80 or 100?

I always thought it was 80, but then I saw several patches/commits by
Dragan Simic which deliberately changed code to make use of 100.
Being fed up with my own confusion, I submitted a PR to 
https://github.com/gregkh/kernel-coding-style/ which got accepted:
https://github.com/gregkh/kernel-coding-style/commit/5c21f99dc79883bd0efeba368193180275c9c77a

So now both the vim plugins code and README say 100.
But as noted in my commit message:

  Note that the current upstream 'Linux kernel coding style' does NOT
  mention the 100 char limit, but only mentions the preferred max length
  of 80.

Or is it 100 for code, but 80 for DeviceTree files and bindings?

Cheers,
  Diederik
