Basically.  I'm a bit surprised that the .init_begin section doesn't show 
up, but I'm pretty sure that this is because .init_begin would have had 
size zero as the previous section's end was already page-aligned.

I don't any good ideas for what in patch is likely to be responsible.  
Would it be helpful to debug if I split this into ~5 very small patches so 
that we can find out what part of the patch is responsible?
