While working on some other cleanups I stumbled over the creation/removal of memblocks in hotplug code and wondered why we still need that. Turns out, we only need that handling with CONFIG_ARCH_KEEP_MEMBLOCK - unless I am missing something important (-> RFC).
I'll be sending out patches to remove CONFIG_ARCH_KEEP_MEMBLOCK on s390x soonish, after finding a way to test them.
Gave it a quick test on x86-64.
