Subject: [PATCH 43/58] mm: Mark fallback version of __early_pfn_to_nid static

mm/page_alloc.c defines a fallback version of __early_pfn_to_nid for
architectures without CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID.  Nothing
outside of mm/page_alloc.c calls that function, so mark it static.  This
eliminates warnings from GCC (-Wmissing-prototypes) and Sparse (-Wdecl).

mm/page_alloc.c:4075:118: warning: no previous prototype for ‘__early_pfn_to_nid’ [-Wmissing-prototypes]
