[PATCH v1 0/2] mm/memory_hotplug: handle memblocks only with CONFIG_ARCH_KEEP_MEMBLOCK

[David Hildenbrand <david@redhat.com>]

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.

Gave it a quick test on x86-64.

RFC -> v1:
- Added ACKs
- Rephrased subject/description of patch #1
- Use IS_ENABLED() instead of ifdefs in patch #2

  mm/memory_hotplug: set node_start_pfn of hotadded pgdat to 0
  mm/memory_hotplug: handle memblocks only with
    CONFIG_ARCH_KEEP_MEMBLOCK
