Thanks a lot for testing.

The imporant part here is testing on top of 
livepatching.git#for-4.7/arch-independent-klp-relocations as well.

I am pretty sure there will be adjustments needed for the merge, as we'll 
have to figure out which parts of ELF can't be thrown away and need to be 
preserved in order for the relocation entry to be successfully 
constructed.

Michael, I think this is an additional reason why the whole final pile 
will have to go through livepatching.git, as the merge with what we have 
in for-4.7/arch-independent-klp-relocations might not be completely 
trivial.
