include/linux/mm.h: remove ifdef condition
The ifdef conditions in include/linux/mm.h presents three cases: - !defined(CONFIG_HAVE_MEMBLOCK_NODE_MAP) && !defined(CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID) There is no actual definition of function but include/linux/mm.h has a static inline stub defined. - defined(CONFIG_HAVE_MEMBLOCK_NODE_MAP) && !defined(CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID) linux/mm.h does not define a prototype, but mm/page_alloc.c defines the function. 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.
