Ok, note that the 2-patch series assumed that it would replace this one,
so it doesn't contain a revert of discarding .eh_frame explicitly for
the compressed kernel.

The first patch of that series at least should be safe enough, it will
stop generating .eh_frame sections in most cases, and shouldn't make any
edge cases worse than before. The second one might be a regression if we
do have some case that still creates them though.
