Seems like I trusted get_maintainer.pl blindly and wasn't selective - it resulted in recipient list much too long. As for this patch, I think I went too far with adding it. The board boots without it properly, and since it covers more general Cortex-M related problems I guess it should be excluded from next iteration of the whole patchset. The problems it adresses may still required further discussion, but I think it should not block the whole thing.
