    mm/sparse: introduce alloc_usemap_and_memmap · 18732093
    Wanpeng Li authored
    After commit 9bdac914 ("sparsemem: Put mem map for one node
    together."), vmemmap for one node will be allocated together, its logic
    is similar as memory allocation for pageblock flags.  This patch
    introduces alloc_usemap_and_memmap to extract the same logic of memory
    alloction for pageblock flags and vmemmap.
