mm: fix section mismatch warning

The register_page_bootmem_info_node() function needs to be marked __init in order to avoid a new warning introduced by commit f65e91d ("mm: use early_pfn_to_nid in register_page_bootmem_info_node"). Otherwise you'll get a warning about how a non-init function calls early_pfn_to_nid (which is __meminit) Cc: Yang Shi <[email protected]> Cc: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
