These are two patches are meant to go on top of the rest of the compiler
attributes series on:

  https://github.com/ojeda/linux/tree/compiler-attributes

which will be sent to Greg for the next merge window.

Please review them and let me know! (specially if someone is against
__fallthrough for some reason :-).

The first patch introduces the attribute and gives the rationale.
The second patch is an example of usage.

This was started in the following thread:

Cheers,
Miguel
