Hence, compiler reports the following warning: mm/page_alloc.c:4300:15: warning: no previous prototype for `__early_pfn_to_nid' [-Wmissing-prototypes] - defined(CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID) The architecture defines the function, and linux/mm.h has a prototype. Thus, join the conditions of Case 2 and 3 ie eliminate the ifdef condition of CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID to eliminate the missing prototype warning from file mm/page_alloc.c.
