BTW it seems with my latest set of patches, modules still have .debug_*.
Can you double check if your tree still has the interim patch which added a linker
script for modules to strip out .debug_*

I'm not planning to carry it and would prefer addressing the the root cause by
removing the -gdwarf-2 toggle. I've added that and pushed rebased series. Care to
take it for a respin please.
