I was thinking of doing this in a full conversion over the full kernel
tree in separate patch(es) after the 7th (maybe for v3?). In
particular, aligned and section have a lot of them:
* 349 ((aligned
* 66 ((__aligned
* 76 ((section
* 48 ((__section
As well as others like:
* 218 ((unused
* 14 ((__unused
But indeed, good catches! These ones I can do it directly here since I
am editing them anyway.

Thanks a lot!
