[RFC PATCH v2 0/4] mm, memory_hotplug: allocate memmap from hotadded memory

Hi, this is the v2 of the first RFC I sent back then in October [1]. In this new version I tried to reduce the complexity as much as possible, plus some clean ups. [Testing] I have tested it on "x86_64" (small/big memblocks) and on "powerpc". On both architectures hot-add/hot-remove online/offli

[RFC PATCH v2 3/4] mm, memory_hotplug: allocate memmap from the added memory range for sparse-vmemmap

Physical memory hotadd has to allocate a memmap (struct page array) for the newly added memory section. Currently, alloc_pages_node() is used for those allocations. This has some disadvantages: a) an existing memory is consumed for that purpose (~2MB per 128MB memory section on x86_64) b) if
