No, the next patch will guard the code but before this patch it was 
simply never applied so it's not a no-op.

I decided to backport them separately even if this patch here isn't 
great and modified right after, so that we preserve a similar history to 
the Linux kernel's.

I can squash them if really desired, but I like not messing too much 
when backporting patches.

Cheers,
Quentin
