  "message": "mm/sparsemem: Allocate mem_section at runtime for CONFIG_SPARSEMEM_EXTREME\u003dy\n\nSize of the mem_section[] array depends on the size of the physical address space.\n\nIn preparation for boot-time switching between paging modes on x86-64\nwe need to make the allocation of mem_section[] dynamic, because otherwise\nwe waste a lot of RAM: with CONFIG_NODE_SHIFT\u003d10, mem_section[] size is 32kB\nfor 4-level paging and 2MB for 5-level paging mode.\n\nThe patch allocates the array on the first call to sparse_memory_present_with_active_regions().\n\nSigned-off-by: Kirill A.
