BTW, now when using ccache 3.2.4 (which I admit is an old release from 2015 but included still in Ubuntu 16.04) I see a lot of fall-through warnings when building the kernel. I reported this to Gustavo before but didn't find the time to answer back to his extra questions, sorry about that.
I did investigate the issue at the time and IIRC it was because ccache strips away the comments (including the fallback comments) before feeding the source file to the compiler. Apparently newer ccache versions has a setting to avoid that but I have not tried upgrading yet. But anyone using old ccache should definitely upgrade.
