    include/linux/mm.h: remove ifdef condition · c558784f
    Rashika Kheria authored
    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.
