Also, turns out you are correct; 3.18.92 fails to build for me as well if I use a recent compiler. It does build with the compiler from Poky 1.3. Bisect points to commit a3a8321bf0f00 ("um: Remove copy&paste code from init.h)"; bisect log is attached. Not sure if it is worth fixing it, though. Maybe I should just stop building it for 3.18 instead. Thoughts ?
