To be honest, my own take on this is that, apart from the compiler cockups trying to do read only annotations, which affect various versions of gcc not just the parisc ones, the _devX annotations are pretty pointless. They only really do something in the non-hotplug case, so since 95% of the world seems to use hotplug now and the other 5% doesn't care that much about the odd page of memory (which you rarely get, since modules sections are accumulated per module, not aggregate), I'd just favour stripping __init and __exit where there's a problem. I think we should simply concentrate on __init and __exit; that's where most of the discard value lies and stop expending huge efforts on the __devX stuff which adds huge complexity for no real gain.
