I have tried this with non-x86 builds and apart of a few problems all looked fine. As it turns out I was using too old cross tools from kernel.org [1]. Luckily Fengguang's kbuild robot did catch a bunch of them (see the patches in this series).
Since Thomas was also surprised that only a bunch of them showed up, I'll better give it another go with more recent compilers.
