[PATCH RFC 0/2] s390/mm: don't set ARCH_KEEP_MEMBLOCK

[David Hildenbrand]

Looking into why we still create memblocks for hotplugged memory (via
add_memory()), I discovered that we might not need ARCH_KEEP_MEMBLOCK on
s390x after all.

After [1] we will no longer create memblocks for hotplugged memory in
case of !CONFIG_ARCH_KEEP_MEMBLOCK. With this series, the same will apply
to standby memory on s390x, added via add_memory().
