The section warnings come about because if something is marked __init but referenced in a function that isn't then an oops could occur because the __init sections are discarded after a certain point in the kernel boot. The same is true for __devinit, etc. So the section warnings are still bugs that need fixing, but they're orthogonal to the memory model for the most part. josh
