From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>
Subject: mm/page_alloc.c: mark bad_range() and meminit_pfn_in_nid() as __maybe_unused
The functions are not used in some configurations. Adding the attribute
fixes the following warnings when building with clang:
mm/page_alloc.c:409:19: error: function 'bad_range' is not needed and
will not be emitted [-Werror,-Wunneeded-internal-declaration]
mm/page_alloc.c:1106:30: error: unused function 'meminit_pfn_in_nid'
[-Werror,-Wunused-function]
