Well... the problem for the current breakage was identified a while ago:

https://lkml.org/lkml/2016/2/10/686

I'm surprised that Al didn't fold my patch into his.  Now that this has 
hit mainline, CONFIG_TRIM_UNUSED_KSYMS is now broken on ARM.

And I don't see how the asm-prototypes.h is going to fix it either (if 
anything, at the moment it looks like it might be another source of 
breakage).

So I think the folowing patch should go into mainline:
