Updated version with Petr's feedback. It looks a bit different and
better now (I would say). Not that it should be considered before we
decide what to do with late module patching, but I finished it before
the discussion started and someone could be interested.

v1: http://lore.kernel.org/r/20190719122840.15353-1-mbenes@suse.cz

Tested on x86_64, ppc64le and s390x. Cross-compiled on arm64 to verify
that nothing is broken.
